ThinkCentre M83, M93/p Hardware Maintenance Manual
Chapter 2. Safety information
This chapter contains the safety information that you need to be familiar with before servicing a computer.
General safety
Follow these rules to ensure general safety:
• Observe good housekeeping in the area of the machines during and after maintenance.
• When lifting any heavy object:
1. Ensure 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.
4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the
muscles in your back.
Attention:
Do not attempt to lift any objects that weigh more than 16 kg (35 lb) or objects that you think are
too heavy for you.
• Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.
• Before you start the machine, ensure that other service representatives and the customer's personnel are
not in a hazardous position.
• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing
the machine.
• Keep your tool case away from walk areas so that other people will not trip over it.
• Do not wear loose clothing that can be trapped in the moving parts of a machine. Ensure 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 a nonconductive clip, approximately
8 centimeters (3 inches) from the end.
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.
Remember: 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 might 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.
Electrical safety
CAUTION:
Electrical current from power, telephone, and communication cables can be hazardous. To avoid
personal injury or equipment damage, disconnect the attached power cords, telecommunication

systems, networks, and modems before you open the computer covers, unless instructed otherwise
in the installation and configuration procedures.
Observe the following rules when working on electrical equipment.
Important: Use only approved tools and test equipment. Some hand tools have handles covered with a soft
material that does not insulate you when working with live electrical currents. Many customers have, near
their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges.
Do not use this type of mat to protect yourself from electrical shock.
• Find the room emergency power-off (EPO) switch, disconnecting 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 equipment that has hazardous voltages.
• Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing Field Replaceable Units (FRUs)
• 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.
Remember: 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.
Remember: There must be a complete circuit to cause electrical shock. By observing the above rule,
you may prevent a current from passing through your body.
– When using a tester, 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; these instructions are in
the safety sections of maintenance information. Use extreme care when measuring 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 that it has been powered-off.
• 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:

– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.
Safety inspection guide
The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these
products. Each machine, as it was designed and built, had required safety items installed to protect users
and service personnel from injury. This guide addresses only those items. However, good judgment should
be used to identify potential safety hazards due to attachment of 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 bulging capacitor
• Mechanical hazards, such as loose or missing hardware
The guide consists of a series of steps presented in a checklist. 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. Power-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 frame ground.
b. The power cord should be the appropriate type as specified in the parts listings.
c. Insulation must not be frayed or worn.
4. Remove the cover.
5. Check for any obvious alterations. Use good judgment as to the safety of any alterations.
6. 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.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.
Handling electrostatic discharge-sensitive devices
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.
Chapter 2. Safety information
5
When handling ESD-sensitive parts:
• Keep the parts in protective packages until they are inserted into the product.
• Avoid contact with other people while handling the part.
• 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 is desirable but not required to protect against ESD damage.
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.
– Use an ESD common ground or reference point when working on a double-insulated or
battery-operated system. You can use coax or connector-outside 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.

Attention
The drives in the computer you are servicing might have been rearranged or the drive startup sequence
changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or
programs can be overwritten if you select an incorrect drive.
General error messages appear if a problem or conflict is found by an application program, the operating
system, or both. For an explanation of these messages, refer to the information supplied with that software
package.
Before replacing any FRUs, ensure that the latest level of BIOS is installed on the system. A down-level BIOS
might cause false errors and unnecessary replacement of the system board. For more information on how to
determine and obtain the latest level BIOS, see “BIOS levels” on page 289.
Use the following procedure to help determine the cause of the problem:
1. Power-off the computer and all external devices.
2. Check all cables and power cords.
3. Set all display controls to the middle position.
4. Power-on all external devices.
5. Power-on the computer.
• Look for displayed error codes
• Listen for beep codes
• Look for readable instructions or a main menu on the display.
If you did not receive the correct response, proceed to step 6 on page 35.
If you do receive the correct response, proceed to step 7 on page 35.
6. Look at the following conditions and follow the instructions:
• If you hear beep codes during POST, go to “Beep symptoms” on page 63.
• If the computer displays a POST error, go to “POST error codes” on page 64.
• If the computer hangs and no error is displayed, continue at step 7 on page 35.
7. Run the Diagnostic programs. See “Diagnostics” on page 55.
• If you receive an error, replace the part that the diagnostic program calls out.
• If the test stops and you cannot continue, replace the last device tested.
Problem determination tips
Due to the variety of hardware and software combinations that can be encountered, use the following
information to assist you in problem determination. If possible, have this information available when
requesting assistance from Service Support and Engineering functions.
• Machine type and model
• Processor or hard disk drive upgrades
• Failure symptom
– Do diagnostics indicate a failure?
– What, when, where, single, or multiple systems?
– Is the failure repeatable?
© Copyright Lenovo 2013
35
– Has this configuration ever worked?
– If it has been working, what changes were made prior to it failing?
– Is this the original reported failure?
• Diagnostics version
– Type and version level
• Hardware configuration
– Print (print screen) configuration currently in use
– BIOS level
• Operating system software
– Type and version level
Notes: To eliminate confusion, identical systems are considered identical only if they:
1. Are the exact machine type and models
2. Have the same BIOS level
3. Have the same adapters/attachments in the same locations
4. Have the same address jumpers/terminators/cabling
5. Have the same software versions and levels
6. Have the same Diagnostic Diskettes (version)
7. Have the same configuration options set in the system
8. Have the same setup for the operating system control files
Comparing the configuration and software set-up between “working and non-working” systems will often
lead to problem resolution.

Chapter 7. Symptom-to-FRU Index
The Symptom-to-FRU index lists error symptoms and possible causes. The most likely cause is listed first.
Always begin with Chapter 4 “General checkout” on page 35. This index can also be used to help you decide
which FRUs to have available when servicing a computer. If you are unable to correct the problem using this
index, go to “Undetermined problems” on page 66.
Notes:
• If you have both an error message and an incorrect audio response, diagnose the error message first.
• If you cannot run the diagnostic tests or you get a diagnostic error code when running a test, but did receive a
POST error message, diagnose the POST error message first.
• If you did not receive any error message, look for a description of your error symptoms in the first part of this index.

operations.
• Checks some basic system-board operations
• Checks the memory operation
• Starts the video operation
• Verifies that the boot drive is working
If the POST detects a problem, an error message appears on the screen. A single problem can cause several
error messages to appear. When you correct the cause of the first error message, the other error messages
probably will not appear on the screen the next time you turn on the system.

Locating internal drives
Internal drives are devices that your computer uses to read and store data. You can add drives to your
computer to increase storage capacity and enable your computer to read other types of media. Internal
drives are installed in bays. In this manual, the bays are referred to as bay 1, bay 2, and so on. Your
computer comes with the following factory-installed drives:
• An optical drive in bay 1
• A 3.5-inch hard disk drive or a 2.5-inch solid state disk in bay 3
When installing or replacing an internal drive, it is important to note the type and size of the drive that you can
install or replace in each bay and correctly connect the cables to the drive installed. Refer to the appropriate
section in Chapter 9 “Replacing FRUs (machine types: 10A0, 10A1, 10A6, 10A7, 10AG, 10AK, 10AL, and
10BE)” on page 93 for instructions on how to install or replace internal drives for your computer.

Locating internal drives
Internal drives are devices that your computer uses to read and store data. You can add drives to your
computer to increase storage capacity and enable your computer to read other types of media. Internal
drives are installed in bays. In this manual, the bays are referred to as bay 1, bay 2, and so on. Your
computer comes with the following factory-installed drives:
• An optical drive in bay 1
• A 3.5-inch hard disk drive or a 2.5-inch solid state disk in bay 3
When installing or replacing an internal drive, it is important to note the type and size of the drive that you can
install or replace in each bay and correctly connect the cables to the drive installed. Refer to the appropriate
section in Chapter 10 “Replacing FRUs (machine types: 10A2, 10A3, 10A8, 10A9, 10AH, 10AJ, 10AM, and
10AN)” on page 159 for instructions on how to install or replace internal drives for your computer.

Recovering from a POST/BIOS update failure
If the power to your computer is interrupted while the POST and BIOS is being updated, your computer
might not restart correctly. If this happens, perform the following procedure to recover from the POST and
BIOS update failure. This procedure is commonly called Boot-block Recovery.
1. Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect
all power cords from electrical outlets and disconnect all cables that are connected to the computer.
2. Open the computer cover. See “Removing the computer cover” on page 94.
3. Remove the hard disk drive. See “Replacing the primary hard disk drive” on page 126
4. Locate the Clear CMOS /Recovery jumper on the system board. See “Locating parts on the system
board” on page 90.
5. Remove any cables that impede access to the Clear CMOS /Recovery jumper.
6. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and
pin 3).
7. Reconnect any cables that were disconnected and reinstall the PCI card if removed.
8. Close the computer cover and reconnect the power cords for the computer and monitor to electrical
outlets. See “Completing the parts replacement” on page 156.
9. Turn on the computer and then insert the POST and BIOS update (flash update) disc into the optical
drive. Wait a few minutes. Then, the recovery session begins. The recovery session will take two to
three minutes. During this time, a warning message will be displayed and no action is needed from you.
10. After the recovery session is completed, there will be no video, and your computer will automatically
turn off.
11. Repeat step 1 through step 5.
12. Move the Clear CMOS /Recovery jumper back to the standard position (pin 1 and pin 2).
13. Reconnect any cables that were disconnected and reinstall the PCI card if removed.
14. Close the computer cover and reconnect any cables that were disconnected.
15. Turn on the computer to restart the operating system.

Power management
Power management reduces the power consumption of certain components of the computer such as the
system power supply, processor, hard disk drives, and some monitors.
Automatic configuration and power interface (ACPI) BIOS
Being an ACPI BIOS system, the operating system is allowed to control the power management features
of the computer and the setting for Advanced Power Management (APM) BIOS mode is ignored. Not
all operating systems support ACPI BIOS mode.
Automatic Power-on features
The Automatic Power-On features within the Power Management menu allow you to enable and disable
features that turn on the computer automatically.
• Wake Up on Alarm: You can specify a date and time at which the computer will be turned on
automatically. This can be either a single event or a daily event.
• Wake on LAN: If the computer has a properly configured token-ring or Ethernet LAN adapter card that is
Wake on LAN-enabled and there is remote network management software, you can use the Wake on LAN
feature. When you set Wake on LAN to Enabled, the computer will turn on when it receives a specific
signal from another computer on the local area network (LAN).
To enable the Wake on LAN function or the Wake Up on Alarm function on the Windows 8 operating system,
do the following:
1. Open Control Panel.
2. Click Hardware and Sound ➙ Power Options.
3. In the left panel, click Choose what the power buttons do.
4. In the Shutdown setting section, clear Turn on fast startup.
Note: If the settings are unavailable, click Change settings that are currently unavailable.
5. Click Save changes.
