IdeaPad Y450 Hardware Maintenance Manual
General safety
Follow these rules below to ensure general safety:
•• Observe a good housekeeping in the area where the machines are put
during and after the maintenance.
•• When lifting any heavy object:
1. Make sure that you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt
to lift it.
4. Lift it by standing or pushing up with your leg muscles; this action could
avoid the strain from the muscles in your back. Do not attempt to lift any
object that weighs more than 16 kg (35 lb) or that you think is too heavy
for you.
•• Do not perform any action that causes hazards to the customer, or that
makes the machine unsafe.
•• Before you start the machine, make sure that other service representatives
and the customer are not in a hazardous position.
•• Place removed covers and other parts in a safe place, keeping them away
from all personnel, while you are servicing the machine.
•• Keep your toolcase away from walk areas so that other people will not trip it
over.
•• Do not wear loose clothing that can be trapped in the moving parts of the
machine. Make sure that your sleeves are fastened or rolled up above your
elbows. If your hair is long, fasten it.
•• Insert the ends of your necktie or scarf inside clothing or fasten it with the
nonconductive clip, about 8 centimeters (3 inches) from the end.
•• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for
your clothing.
Attention: Metal objects are good electrical conductors.
•• Wear safety glasses when you are hammering, drilling, soldering, cutting
wire, attaching springs, using solvents, or working in any other conditions
that may be hazardous to your eyes.
•• After service, reinstall all safety shields, guards, labels, and ground wires.
Replace any safety device that is worn or defective.
•• Reinstall all covers correctly before returning the machine to the customer.
•• Fan louvers on the machine help to prevent the overheating of internal
components. Do not obstruct fan louvers or cover them with labels or
stickers.

Safety information
Electrical safety
Observe the following rules when working on electrical equipments.
Important:
Use only approved tools and test equipments. Some hand tools have handles
covered with a soft material that does not insulate you when working with live
electrical currents.
Many customers have rubber floor mats near their machines that contain small
conductive fibers to decrease electrostatic discharges. Do not use such kind of mat
to protect yourself from electrical shock.
•• Find the room emergency power-off (EPO) switch, disconnecting the switch
or electrical outlet. If an electrical accident occurs, you can then operate the
switch or unplug the power cord quickly.
•• Do not work alone under hazardous conditions or near the equipment that
has hazardous voltages.
•• Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
•• Before you start to work on the machine, unplug the power cord. If you
cannot unplug it, ask the customer to power-off the wall box that supplies
power to the machine, and to lock the wall box in the off position.
•• If you need to work on a machine that has exposed electrical circuits,
observe the following precautions:
– Ensure that another person, familiar with the power-off controls, is near
you.
Attention: Another person must be there to switch off the power, if
necessary.
– Use only one hand when working with powered-on electrical equipment;
keep the other hand in your pocket or behind your back.
Attention: An electrical shock can occur only when there is a complete
circuit. By observing the above rule, you may prevent a current from
passing through your body.
– When using testers, set the controls correctly and use the approved
probe leads and accessories for that tester.
– Stand on suitable rubber mats (obtained locally, if necessary) to insulate
you from grounds such as metal floor strips and machine frames.
Observe the special safety precautions when you work with very high voltages;
instructions for these precautions are in the safety sections of maintenance
information. Be extremely careful when you measure the high voltages.
•• Regularly inspect and maintain your electrical hand tools for safe operational
condition.
•• Do not use worn or broken tools and testers.
•• Never assume that power has been disconnected from a circuit. First, check
it to make sure that it has been powered off.
3
IdeaPad Y450 Hardware Maintenance Manual
•• Always look carefully for possible hazards in your work area. Examples of
these hazards are moist floors, nongrounded power extension cables, power
surges, and missing safety grounds.
•• Do not touch live electrical circuits with the reflective surface of a plastic
dental mirror. The surface is conductive; such touching can cause personal
injury and machine damage.
•• Do not service the following parts with the power on when they are removed
from their normal operating places in a machine:
– Power supply units
– Pumps
– Blowers and fans
– Motor generators
and similar units. (This practice ensures correct grounding of the units.)
•• If an electrical accident occurs:
– Caution: do not become a victim yourself.
– Switch off the power.
– Send the victim to get medical aid.

Safety information
Safety inspection guide
The purpose of this inspection guide is to assist you in identifying potential
unsafe conditions. As each machine was designed and built, required safety
items were installed to protect users and service personnel from injury. This
guide addresses only those items. You should use good judgment to identify
potential safety hazards according to the attachment of non-Lenovo IdeaPad
features or options not covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the
apparent hazard could be and whether you can continue without first correcting
the problem.
Consider these conditions and the safety hazards they present:
•• Electrical hazards, especially primary power (primary voltage on the frame
can cause serious or fatal electrical shock)
•• Explosive hazards, such as a damaged CRT face or a bulging capacitor
•• Mechanical hazards, such as loose or missing hardware
To determine whether there are any potential unsafe conditions, use the
following checklist at the beginning of every service task. Begin the checks with
the power off, and the power cord disconnected.
Checklist:
1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Turn off the computer. Disconnect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition. Use a meter to measure
third-wire ground continuity for 0.1 ohm or less between the external
ground pin and the frame ground.
b. The power cord should be the type specified in the parts list.
c. Insulation must not be frayed or worn.
4. Check for cracked or bulging batteries.
5. Remove the cover.
6. Check for any obvious non-Lenovo IdeaPad alterations. Use good judgment
as to the safety of any non-Lenovo IdeaPad alterations.
7. Check inside the unit for any obvious unsafe conditions, such as metal
filings, contamination, water or other liquids, or signs of fire or smoke
damage.
8. Check for worn, frayed, or pinched cables.
9. Check that the power-supply cover fasteners (screws or rivets) have not
been removed or tampered with.

IdeaPad Y450 Hardware Maintenance Manual
Handling devices that are sensitive to electrostatic discharge
Any computer part containing transistors or integrated circuits (ICs) should be
considered sensitive to electrostatic discharge (ESD). ESD damage can occur
when there is a difference in charge between objects. Protect against ESD
damage by equalizing the charge so that the machine, the part, the work mat,
and the person handling the part are all at the same charge.
Notes:
1. Use product-specific ESD procedures when they exceed the requirements
noted here.
2. Make sure that the ESD protective devices you use have been certified (ISO
9000) as fully effective.
When handling ESD-sensitive parts:
•• Keep the parts in protective packages until they are inserted into the product.
•• Avoid contact with other people.
•• Wear a grounded wrist strap against your skin to eliminate static on your
body.
•• Prevent the part from touching your clothing. Most clothing is insulative and
retains a charge even when you are wearing a wrist strap.
•• Use the black side of a grounded work mat to provide a static-free work
surface. The mat is especially useful when handling ESD-sensitive devices.
•• Select a grounding system, such as those listed below, to provide protection
that meets the specific service requirement.
Note:
The use of a grounding system to guard against ESD damage is desirable but not
necessary.
– Attach the ESD ground clip to any frame ground, ground braid, or greenwire ground.
– When working on a double-insulated or battery-operated system, use an
ESD common ground or reference point. You can use coax or connectoroutside shells on these systems.
– Use the round ground prong of the ac plug on ac-operated computers.
Grounding requirements
Electrical grounding of the computer is required for operator safety and correct
system function. Proper grounding of the electrical outlet can be verified by a
certified electrician.

Strategy for replacing FRUs
Before replacing parts:
Make sure that all software fixes, drivers, and BIOS downloads are installed
before replacing any FRUs listed in this manual.
After a system board is replaced, ensure that the latest BIOS is loaded to the
system board before completing the service action.
To download software fixes, drivers, and BIOS, follow the steps below:
1. Go to http://www.lenovo.com/support.
2. Enter the product number of the computer or press Auto-detect button on
the screen.
3. Select Downloads and drivers.
4. Follow the directions on the screen and install the necessary software.
16
Important service information
Use the following strategy to prevent unnecessary expense for replacing and
servicing FRUs:
•• If you are instructed to replace a FRU, but the replacement does not solve
the problem, reinstall the original FRU before you continue.
•• Some computers have both a processor board and a system board. If you
are instructed to replace either of them, and replacing one of them does not
solve the problem, reinstall that board, and then replace the other one.
•• If an adapter or a device consists of more than one FRU, any of the FRUs
may be the cause of the error. Before replacing the adapter or device,
remove the FRUs one by one to see if the symptoms change. Replace only
the FRU that changed the symptoms.
Attention: The setup configuration on the computer you are servicing may
have been customized. Running Automatic Configuration may alter the
settings. Note the current configuration settings (using the View Configuration
option); then, when service has been completed, verify that those settings
remain in effect.
Strategy for replacing a hard disk drive
Always try to run a low-level format before replacing a hard disk drive. This
will cause all customer data on the hard disk to be lost. Make sure that the
customer has a current backup of the data before performing this action.
Attention: The drive startup sequence in the computer you are servicing may
have been changed. Be extremely careful during write operations such as
copying, saving, or formatting. If you select an incorrect drive, data or programs
can be overwritten.
Important notice for replacing a system board
Some components mounted on a system board are very sensitive. Improper
handling can cause damage to those components, and may cause a system
malfunction.
Attention: When handling a system board:
•• Do not drop the system board or apply any excessive force to it.
•• Avoid rough handling of any kind.
•• Avoid bending the system board and hard pushing to prevent cracking at
each BGA (Ball Grid Array) chipset.
How to use error message
Use the error codes displayed on the screen to diagnose failures. If more
than one error code is displayed, begin the diagnosis with the first error code.
Whatever causes the first error code may also cause false error codes. If
no error code is displayed, see whether the error symptom is listed in the
Symptom-to-FRU Index for the computer you are servicing.

Strategy for replacing FRUs for CTO, CMV, and GAV
Product definition
Dynamic Configure To Order (CTO)
This provides the ability for a customer to configure an IBM® or a Lenovo
solution from an eSite, and have this configuration sent to fulfillment, where
it is built and shipped directly to the customer. The machine label, Product
Entitlement Warehouse (PEW), eSupport, and the HMM will load these
products as the 4-digit MT and 3-digit model, where model = “CTO” (Example:
1829-CTO).
Custom Model Variant (CMV)
This is a unique configuration that has been negotiated between IBM or
Lenovo and the customer. A unique 4-digit MT and 3-digit model is provided
to the customer to place orders (Example: 1829-W15). A CMV is a special bid
offering. Therefore, it is NOT generally announced.
•• The MTM portion of the machine label is the 4-digit MT and 3-digit model,
where model = “CTO” (Example: 1829-CTO). The PRODUCT ID portion of
the machine label is the 4-digit MT and 3-digit CMV model (Example: 1829W15).
•• The PEW record is the 4-digit MT and 3-digit model, where model = “CTO”
(Example: 1829-CTO).
•• eSupport will show both the CTO and CMV machine type models (Example:
1829-CTO and 1829-W15 will be found on the eSupport site).
•• The HMM will have the 4-digit MT and 3-digit CTO model only (Example:
1829-CTO). Again, CMVs are custom models and are not found in the HMM.
General Announce Variant (GAV)
This is a standard model (fixed configuration). GAVs are announced and
offered to all customers. The MTM portion of the machine label is a 4-digit MT
and 3-digit model, where model = a “fixed part number”, not “CTO” (Example:
1829-F1U). Also, PEW, eSupport, and the HMM will list these products under
the same fixed model number.
FRU identification for CTO, CMV, and GAV products
There are three information resources to identify which FRUs are used to
support CTO, CMV, and GAV products. These sources are PEW, eSupport,
and the HMM.
Using PEW
•• PEW is the primary source for identifying FRU part numbers and FRU
descriptions for the key commodities for CTO, CMV and GAV products at
a MT - serial number level. An example of key commodities are hard disk
drives, system boards, microprocessors, Liquid Crystal Displays (LCDs),
and memory.
•• Remember, all CTO and CMV products are loaded in PEW under the 4-digit
MT and 3-digit model, where model = “CTO” (Example: 1829-CTO). GAVs
are loaded in PEW under the 4-digit MT and 3-digit model, where model = a
“fixed part number”, not “CTO” (Example: 1829-F1U).
•• PEW can be accessed at the following Web site:
http://w3-01.ibm.com/pc/entitle/pg2/Service.wss/display/Home.
18
Important service information
Customers can also access PEW via
http://www-307.ibm.com/pc/support/site.wss/product.do?template=/
warranty/warranty.vm&sitestyle=lenovo.
Select Warranty lookup. Input the MT and the Serial number and the list of
key commodities will be returned in the PEW record under COMPONENT
INFORMATION.
•• Business Partners using Eclaim will access PEW when performing
Entitlement Lookup. Business Partners will enter Loc ID, MT and Serial, and
the key commodities will be returned in the Eclaim record under SYSTEM
DETAILS.
•• Authorized IBM Business Partners can access Eclaim at the following Web
site: https://wca.eclaim.com.
Using eSupport
For Key Commodities (Examples - hard disk drive, system board,
microprocessor, LCD, and memory)
•• eSupport can be used to view the list of key commodities built in a particular
machine serial (this is the same record found in PEW).
•• eSupport can be accessed at the following Web site:
http://www.lenovo.com/support.
•• To view the key commodities, click on PARTS INFORMATION, then PARTS
LOOKUP. Enter the model type and serial number. The key commodities will
be returned in the eSupport record under PARTS SHIPPED WITH YOUR
SYSTEM.
For the Remaining FRUs (the complete list of FRUs at the MT Model level)
•• Support can be used to view the complete list of FRUs for a machine type
and model.
•• To view the complete list of FRUs, Enter the machine type and model
(Example: 1829-CTO) under QUICK PATH. Select PARTS INFORMATION
under “View by Document Type”. Select SERVICE PARTS under “Filter by
Category”. Select SYSTEM SERVICE PARTS under “Parts Information by
Date”. The list of service parts by description, with applicable machine type
model and FRU will be displayed.
Using the HMM
For Key Commodities (Examples - hard disk drive, system board,
microprocessor, LCD, and memory)
Use the HMM as a back-up to PEW and eSupport to view the complete list of
FRUs at the MT Model level.

Important information about replacing RoHS compliant FRUs
RoHS, The Restriction of Hazardous Substances in Electrical and
Electronic Equipment Directive (2002/95/EC) is a European Union legal
requirement affecting the global electronics industry. RoHS requirements
must be implemented on Lenovo products placed on the market after
June 2006. Products on the market before June 2006 are not required to
have RoHS compliant parts. If the original FRU parts are non-compliant,
replacement parts can also be non-compliant. In all cases if the original
FRU parts are RoHS compliant, the replacement part must also be RoHS
compliant.
Note: RoHS and non-RoHS FRU part numbers with the same fit and function
are identified with unique FRU part numbers.
Lenovo plans to transit to RoHS compliance well before the implementation
date and expects its suppliers to be ready to support Lenovo’s requirements
and schedule in the EU. Products sold in 2005 and 2006 will contain some
RoHS compliant FRUs. The following statement pertains to these products and
any product Lenovo produces containing RoHS compliant FRUs.
RoHS compliant FRUs have unique FRU part numbers. Before or after the
RoHS implementation date, failed RoHS compliant parts must always be
replaced with RoHS compliant ones, so only the FRUs identified as compliant
in the system HMM or direct substitutions for those FRUs may be used.

•• “Power system checkout” on page 23
Before you go to the checkout, make sure to read the following important notes:
Important notes:
• Only certified trained personnel can service the computer.
• Before replacing any FRU, read the entire page on removing and replacing
FRUs.
• When you replace FRUs, use new nylon-coated screws.
• Be extremely careful during such write operations as copying, saving, or
formatting. Drives in the computer that you are servicing sequence might
have been altered. If you select an incorrect drive, data or programs might be
overwritten.
• Replace a FRU only with another FRU of the correct model. When you
replace a FRU, make sure that the machine model and the FRU part number are
correct by referring to the FRU parts list.
• A FRU should not be replaced just because of a single, unreproducible failure.
Single failures can occur for a variety of reasons that have nothing to do with a
hardware defect, such as cosmic radiation, electrostatic discharge, or software
errors. Consider replacing a FRU only when a problem recurs. If you suspect that
a FRU is defective, clear the error logs and run the test again. If the error does not
recur, do not replace the FRU.
• Be careful not to replace a nondefective FRU.
21
IdeaPad Y450 Hardware Maintenance Manual

•• Missing parts might be a symptom of unauthorized service or modification.
•• If the spindle of a hard disk drive becomes noisy, it may have been subjected
to excessive force, or dropped.
General checkout
Power system checkout
To verify a symptom, follow the steps below:
1. Turn off the computer.
2. Remove the battery pack.
3. Connect the AC adapter.
4. Make sure that power is supplied when you turn on the computer.
5. Turn off the computer.
6. Disconnect the AC adapter and install the charged battery pack.
7. Make sure that the battery pack supplies power when you turn on the
computer.
If you suspect a power problem, see the appropriate one of the following power
supply checkouts:
•• “Checking the AC adapter ” on page 23
•• “Checking operational charging” on page 23
•• “Checking the battery pack ” on page 24
Checking the AC adapter
You are here because the computer fails only when the AC adapter is used.
•• If the power-on indicator does not turn on, check the power cord of the AC
adapter for correct continuity and installation.
•• If the computer does not charge during operation, go to “Checking
operational charging”.
To check the AC adapter, follow the steps below:
1. Unplug the AC adapter cable from the computer.
2. Measure the output voltage at the plug of the AC adapter cable. See the
following figure:

Note: Output voltage for the AC adapter pin No. 2 may different from the one
you are servicing.
3. If the voltage is not correct, replace the AC adapter.
4. If the voltage is acceptable, do the following:
•• Replace the system board.
•• If the problem continues, go to “Lenovo IdeaPad Y450” on page 39.
Note: Noise from the AC adapter does not always indicate a defect.
Checking operational charging
To check whether the battery charges properly during operation, use a
discharged battery pack or a battery pack that has less than 50% of the total
power remaining when installed in the computer.
23
IdeaPad Y450 Hardware Maintenance Manual
Perform operational charging. If the battery status indicator or icon does not
light on, remove the battery pack and let it return to room temperature. Reinstall
the battery pack. If the charge indicator or icon is still off, replace the battery
pack.
If the charge indicator still does not light on, replace the system board. Then
reinstall the battery pack. If it is still not charged, go to the next section.
Checking the battery pack
Battery charging does not start until the Power Meter shows that less than 95%
of the total power remains; under this condition the battery pack can charge to
100% of its capacity. This protects the battery pack from being overcharged or
from having a shortened life.
To check your battery, move your cursor to the Power Meter icon in the icon
tray of the Windows® taskbar and wait for a moment (but do not click it), and the
percentage of battery power remaining is displayed. To get detailed information
about the battery, double-click the Power Meter icon.
Note: If the battery pack becomes hot, it may not be able to be charged.
Remove it from the computer and leave it at room temperature for a while. After
it cools down, reinstall and recharge it.
To check the battery pack, follow the steps below:
1. Turn off the computer.
2. Remove the battery pack and measure the voltage between battery
terminals 1 (+) and 7 (-). See the following figure:
1(+)
2(+)

3. If the voltage is less than +11.0 V DC, the battery pack has been
discharged.
Note: Recharging will be continued for at least 3 hours, even though the
indicator does not light on.
If the voltage is still less than +11.0 V DC after recharging, replace the
battery.
4. If the voltage is more than +11.0 V DC, measure the resistance between
battery terminals 5 and 7. The resistance must be 4 to 30 KΩ.
If the resistance is not correct, replace the battery pack. If the resistance is
correct, replace the system board.

Restoring the factory contents by using OneKey Recovery
Restore of factory default
The IdeaPad Y450 computers come with pre-installed OneKey Rescue System.
In order to save application files and the initial backed up files of the system,
the hard disk in a Lenovo computer includes a hidden partition when it is
shipped. If you need to restore the system to the point of your first boot up, just
enter Lenovo OneKey Rescue System and run Restore to factory default. For
details of OneKey Rescue System, see the User Guide for OneKey Rescue System.
Note: This will delete all the new data on the system partition (C drive), which
is not recoverable. Make sure to back up your critical data before you perform this
action.
Using recovery disks
When you replace a hard disk drive in your computer, you are unable to use
the pre-installed Lenovo OneKey Recovery and OneKey Rescue. However, you
can use the recovery disks that store your backed up data to restore your new
hard drive to a previous backup status.
Note: You can create recovery disks by burning the backup image to a CD/DVD
as recovery disks. For details of Create recovery disks, see the User Guide for
OneKey Rescue System.
25
IdeaPad Y450 Hardware Maintenance Manual
When you use the recovery disks to boot your computer, the system will enter
the user interface for system recovery automatically. Please follow the prompt
to insert the backup disks to complete the whole recovery process.
Note: The recovery process might take up to 2 hours.
Passwords
As many as three passwords may be needed for any Lenovo IdeaPad
computer: the power-on password (POP), the hard-disk password (HDP), and
the supervisor password (SVP).
If any of these passwords has been set, a prompt for it appears on the screen
whenever the computer is turned on. The computer does not start until the
password is entered.
Exception: If only an SVP is installed, the password prompt does not appear
when the operating system is booted.
Power-on password
A power-on password (POP) protects the system from being powered on by
an unauthorized person. The password must be entered before an operating
system can be booted.
Hard-disk password
There are two hard-disk passwords (HDPs):
•• User HDP—for the user
•• Master HDP—for the system administrator, who can use it to get access to
the hard disk even if the user has changed the user HDP
Note: There are two modes for the HDP: User only and Master + User. The
Master + User mode requires two HDPs; the system administrator enters both
in the same operation. The system administrator then provides the user HDP to
the system user.
Attention: If the user HDP has been forgotten, check whether a master HDP
has been set. If it has, it can be used for access to the hard disk drive. If no
master HDP is available, neither Lenovo nor Lenovo authorized servicers
provide any services to reset either the user or the master HDP, or to recover
data from the hard disk drive. The hard disk drive can be replaced for a
scheduled fee.
26
Related service information
Supervisor password
A supervisor password (SVP) protects the system information stored in the
BIOS Setup Utility. The user must enter the SVP in order to get access to the
BIOS Setup Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to
the servicer, there is no service procedure to reset the password. The system
board must be replaced for a scheduled fee.
How to remove the hard-disk password
Attention: If User only mode is selected and the user HDP has been forgotten
and cannot be made available to the servicer, neither Lenovo nor Lenovo
authorized servicers provide any services to reset the user HDPs or to recover
data from the hard disk drive. The hard disk drive can be replaced for a
scheduled fee.
To remove a user HDP that has been forgotten, when the SVP and the master
HDP are known, follow the steps below:
1. Turn on the computer; while the initial screen is displayed, press F2; then
the BIOS Setup Utility screen opens.
2. Select Security, using the cursor directional keys to move down the menu.
3. Select Password.
4. Select Hard-disk x password, where x is the letter of the hard disk drive. A
pop-up window opens.
5. Select Master HDP.
6. Type the current master HDP in the Enter Current Password field. then
leave the Enter New Password field blank, and press Enter twice.
7. Press F10.
8. Select Yes in the Setup Configuration window. Both user HDP and master
HDP will have been removed.

Related service information
Hibernation mode
In hibernation mode, the following occurs:
•• The system status, RAM, VRAM, and setup data are stored on the hard disk.
•• The system is powered off.
To cause the computer to enter hibernation mode, follow the steps below:
•• If you are using the ACPI operating system and have defined one of the
following actions as the event that causes the system to go into hibernation
mode, perform that action:
– Closing the lid.
– Pressing the power button.
Also, the computer goes into hibernation mode automatically in either of the
following conditions:
•• If a “hibernation time” has been set on the timer, and if the user does not do
any operation with the keyboard, the hard disk drive, the parallel connector,
or the diskette drive within that time.
•• If the timer conditions are satisfied in suspend mode.
When the power is turned on, the computer returns from hibernation mode and
resumes operation. The hibernation file in the boot record on the hard disk drive
is read, and system status is restored from the hard disk drive.

LCD-related symptoms
Important:
The TFT LCD for the notebook computer contains many thin-film transistors
(TFTs). The presence of a small number of dots that are missing, discolored,
or always lighted is characteristic of TFT LCD technology, but excessive pixel
problems can cause viewing concerns. The LCD should be replaced if the number
of missing, discolored, or lighted dots in any background is as follows:

Intermittent problems
Intermittent system hang problems can be due to a variety of causes that have
nothing to do with a hardware defect, such as cosmic radiation, electrostatic
discharge, or software errors. FRU replacement should be considered only
when a problem recurs.
When analyzing an intermittent problem, follow the steps below:
1. Run the diagnostic test for the system board in loop mode at least 10 times.
2. If no error is detected, do not replace any FRUs.
3. If any error is detected, replace the FRU shown by the FRU code. Rerun the
test to verify that no more errors exist.
Undetermined problems
If the diagnostic tests did not identify the adapter or device that has failed, if
wrong devices are installed, or if the system simply is not operating, follow
these procedures to isolate the failing FRU (do not isolate FRUs that have no
defects).
Verify that all attached devices are supported by the computer.
Verify that the power supply being used at the time of the failure is operating
correctly. (See “Power system checkout” on page 23.)
1. Turn off the computer.
2. Visually check each FRU for damage. Replace any damaged FRU.
3. Remove or disconnect all of the following devices:
a. Non-Lenovo IdeaPad devices
b. Devices attached to the docking station or the port replicator
c. Printer, mouse, and other external devices
d. Battery pack
e. Hard disk drive
f. External diskette drive or optical drive
g. DIMM
h. Optical disk or diskette in the internal drive
i. PC Cards
4. Turn on the computer.
5. Determine whether the problem has been solved.
6. If the problem does not recur, reconnect the removed devices one at a time
until you find the failing FRU.
7. If the problem remains, replace the following FRUs one at a time (do not
replace a nondefective FRU):

FRU replacement notices
This section presents notices related to removing and replacing parts. Read
this section carefully before replacing any FRU.
Screw notices
Loose screws can cause a reliability problem. In the Lenovo IdeaPad computer,
this problem is addressed with special nylon-coated screws that have the
following characteristics:
•• They maintain tight connections.
•• They do not easily come loose, even with shock or vibration.
•• They are harder to tighten.
•• Each one should be used only once.
Do the following when you service this machine:
•• Keep the screw kit (for the P/N, see “Miscellaneous parts” on page 98) in
your tool bag.
•• Always use new screws.
•• Use a torque screwdriver if you have one.
Tighten screws as follows:
•• Plastic to plastic
Turn an additional 90° after the screw head touches the surface of the
plastic part:
more than 90°
(Cross-section)
•• Logic card to plastic
Turn an additional 180° after the screw head touches the surface of the
logic card:
more than 180°
(Cross-section)
•• Torque driver
If you have a torque screwdriver , refer to the “Torque” column for each step.
•• Make sure that you use the correct screws. If you have a torque screwdriver,
tighten all screws firmly to the torque shown in the table. Never use a
screw that you removed. Use a new one. Make sure that all screws are
tightened firmly.
•• Ensure torque screwdrivers are calibrated correctly following country
specifications.

Lenovo IdeaPad Y450
Retaining serial numbers
This section presents the following descriptions:
•• “Restoring the serial number of the system unit” on page 47
•• “Retaining the UUID” on page 48
•• “Reading or writing the ECA information ” on page 49
Restoring the serial number of the system unit
When the computer was manufactured, the EEPROM on the system board was
loaded with the serial numbers of the system and all major components. These
numbers need to remain the same throughout the life of the computer.
If you replace the system board, you must restore the serial number of the
system unit to its original value.
Before replacing the system board, save the original serial number by doing the
following:
1. Install the CE Utility Diskette for Lenovo IdeaPad notebooks, and restart the
computer.
2. From the main menu, select 1. Set System Identification.
3. Select 2. Read S/N data from EEPROM.
The serial number of each device in your computer is displayed; the serial
number of the system unit is listed as follows:
•• 20: Serial number
Write down that number.
Note: The serial number of the system unit is also written on the label attached
to the bottom of the computer.
After you have replaced the system board, restore the serial number by doing
the following:
1. Install the CE Utility Diskette for Lenovo IdeaPad notebooks and restart the
computer.
2. From the main menu, select 1. Set System Identification.
3. Select 1. Add S/N data from EEPROM.
Follow the instructions on the screen.
If the MTM and Product ID numbers differ from each other on the rear label,
apply what is shown for the Product ID field. See the following example:
MTM on rear label:
TTTT-CTO S/N SSSSSSS
Product ID on rear label:
TTTT-MMM (apply this number when setting Serial Number)
In the example, the Serial Number to be applied is ‘1STTTTMMMSSSSSSS’.
47
IdeaPad Y450 Hardware Maintenance Manual
Retaining the UUID
The Universally Unique Identifier (UUID) is a 128-bit number uniquely assigned
to your computer at its production and stored in the EEPROM of your system
board. The algorithm that generates the number is designed to provide unique
IDs until the year A.D. 3400. No two computers in the world have the same
number.
When you replace the system board, you must set the UUID on the new
system board as follows:
1. Install the CE Utility Diskette for Lenovo IdeaPad notebooks, and restart the
computer.
2. From the main menu, select 4. Assign UUID.
A new UUID is created and written. If a valid UUID already exists, it is not
overwritten.
48
Lenovo IdeaPad Y450
Reading or writing the ECA information
Information on Engineering Change Announcements (ECA) are stored in
the EEPROM of the system board. The electronic storage of this information
simplifies the procedure to check if the ECA has been previously applied to a
machine. The machine does not need to be disassembled to check for the ECA
application.
To check what ECAs have been previously applied to the machine, enable
the ECA Information Read/Write function on the CE Utility Diskette for Lenovo
IdeaPad notebooks.
1. Insert the CE Utility Diskette for Lenovo IdeaPad notebooks, and restart the
computer.
2. From the main menu, select 6. Set ECA Information.
3. To read ECA information, select 2. Read ECA/rework number from
EEPROM and follow the instructions.
4. To read box build date, select 5. Read box build date from EEPROM, and
follow the instructions on the screen.
After an ECA has been applied to the machine, the EEPROM must be updated
to reflect the ECA’s application. Apply the CE Utility Diskette for Lenovo
IdeaPad notebooks to update the EEPROM.
Note: Only the ECA number is stored in the EEPROM. The machine type of
the ECA is assumed as the same as that of the machine which had the ECA
applied to it.
1. Insert the CE Utility Diskette for Lenovo IdeaPad notebooks, and restart the
computer.
2. From the main menu, select 6. Set ECA Information.
3. To write ECA information, select 1. Write ECA/rework number from
EEPROM, and follow the instructions.
4. To write box build date, select 4. Write box build date from EEPROM, and
follow the instructions on the screen.
If the system board is being replaced, try to read the ECA information from the
old system board and transfer the information to the new system. If the system
board is inoperable, this will not be possible.

These CRUs are isolated parts within the computer that are concealed
by an access panel that is typically secured by more than two screws.
Once the access panel is removed, the specific CRU is visible.
• A RoHS compliant FRU is identified by an R. An N in the RoHS ID column
means the part is not a RoHS compliant FRU.
• FRUs marked with OP are available as options.
