Activating and Customizing the
Software
NOTE: This chapter provides information for both Windows 7 and Windows 8.
Activating and customizing the software in
Windows 7
If your computer was not shipped with a Windows® operating system, some portions of this
documentation do not apply. Additional information is available in online help after you activate the
operating system.
CAUTION: Do not add optional hardware or third-party devices to the computer until the operating
system is successfully activated. Doing so may cause errors and prevent the operating system from
installing properly.
NOTE: Be sure there is a 10.2 cm (4 inch) clearance at the back of the unit and above the monitor to
permit the required airflow.
Activating the Windows operating system
The first time you turn on the computer, the operating system is set up and activated automatically. This
process takes about 5 to 10 minutes. Carefully read and follow the instructions on the screen to
complete the activation.
We recommend that you register your computer with HP during operating system setup so you can
receive important software updates, facilitate support questions, and sign up for special offers.
CAUTION: After the activation process has begun, DO NOT TURN OFF THE COMPUTER UNTIL THE
PROCESS IS COMPLETE. Turning off the computer during the activation process may damage the
software that runs the computer or prevent its proper installation.
NOTE: If the computer shipped with more than one operating system language on the hard drive, the
activation process could take up to 60 minutes.

the Browse button in the dialog box to locate the i386 folder. This action points the operating system
to the appropriate drivers.

http://www.hp.com/support. Select your country and language, select Download drivers and
software (and firmware), enter the model number of the computer, and press Enter.

Routine care, SATA drive
guidelines, and disassembly
preparation
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to
the system board. You must disconnect the power cord from the power source before opening the
computer to prevent system board or component damage.
Electrostatic discharge information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work
perfectly throughout a normal cycle. The device may function normally for a while, but it has been
degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.

Operating guidelines
To prevent overheating and to help prolong the life of the computer:
20
●
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
●
Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented
sides of the computer and above the monitor to permit the required airflow.
●
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
●
Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign
matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning
the air vents.
●
Never operate the computer with the cover or side panel removed.
●
Do not stack computers on top of each other or place computers so near each other that they are
subject to each other’s re-circulated or preheated air.
●
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must
be provided on the enclosure, and the same operating guidelines listed above will still apply.
●
Keep liquids away from the computer and keyboard.

SATA data cable
Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA
1.5 Gb/s drives.
Current HP desktop products ship with SATA 3.0 Gb/s hard drives.
SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and never
bend it tighter than a 30 mm (1.18 in) radius.
The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.
SMART ATA drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an
impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure
indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If
the drive determines that a failure is imminent, it generates a fault alert.
Cable management
Always follow good cable management practices when working inside the computer.
●
Keep cables away from major heat sources like the heat sink.
●
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
are not designed to take excessive pressure on them.
●
Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when
the parts are moved.
●
When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the
wires.
●
Some flat ribbon cables come prefolded. Never change the folds on these cables.
●
Do not bend any cable sharply. A sharp bend can break the internal wires.
●
Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
●
Never crease a SATA data cable.
●

Memory module, 2-GB
689372-001
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3LSDRAM) dual inline memory modules (SODIMMs).
DDR3L-SDRAM SODIMMs
The system board offers two memory sockets.
These memory sockets are populated with at least one preinstalled SODIMM. To achieve the maximum
memory support, you can populate the system board with up to 8-GB of memory.
For proper system operation, the DDR3L SODIMMs must be:
●
industry-standard 204-pin
●
unbuffered non-ECC PC3L-12800 DDR3L-1600 MHz-compliant
●
1.35 volt DDR3L-SDRAM SODIMMs
The DDR3L SODIMMs must also:
●
support CAS latency 11 DDR3L 1600 MHz (11-11-11 timing)
●
contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
In addition, the computer supports:
●
2-Gbit and 4-Gbit non-ECC memory technologies
●
single-sided and double-sided SODIMMs
●
SODIMMs constructed with x8 and x16 DDR devices; SODIMMs constructed with x4 SDRAM are
not supported
NOTE: The system will not operate properly if you install unsupported SODIMMs.
Memory
29
Populating DIMM sockets
There are two SODIMM sockets on the system board, with one socket per channel. The sockets are
labeled DIMM1 and DIMM2. The DIMM1 socket operates in memory channel A. The DIMM2 socket
operates in memory channel B.

NOTE:
Insertion Order
A memory module must occupy the XMM1/Channel A socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the SODIMMs are installed.
30
●
The system will operate in single channel mode if the SODIMM sockets are populated in one
channel only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity of
the SODIMM in Channel A is equal to the total memory capacity of the SODIMM in Channel B.
●
The system will operate in flex mode if the memory capacity of the SODIMM in Channel A is not
equal to the memory capacity of the SODIMM in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
Chapter 6 Removal and replacement procedures
and the remainder is assigned to single channel. If one channel will have more memory than the
other, the larger amount should be assigned to channel A.
●
In any mode, the maximum operational speed is determined by the slowest SODIMM in the
system.
Removing memory modules
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power
to drain before adding or removing memory modules. Regardless of the power-on state, voltage is
always supplied to the memory modules as long as the computer is plugged into an active AC outlet.
Adding or removing memory modules while voltage is present may cause irreparable damage to the
memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or
oxidation resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object.

POST Error Messages
This appendix lists the error codes, error messages, and the various indicator light and audible
sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable
source of the problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count and
non-error text messages. If a POST error occurs, the screen will display the error message. To manually
switch to the POST Messages Enabled mode during POST, press any key (except F10, F11, or F12).
The default mode is POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are
determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory
test. Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish
the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.
NOTE: For more information on Computer Setup, see Computer Setup (F10) Utility on page 54.

Password Security and Resetting
CMOS
This computer supports security password features, which can be established through the Computer
Setup Utilities menu.
This computer supports two security password features that are established through the Computer Setup
Utilities menu: setup password and power-on password. When you establish only a setup password,
any user can access all the information on the computer except Computer Setup. When you establish
only a power-on password, the power-on password is required to access Computer Setup and any
other information on the computer. When you establish both passwords, only the setup password will
give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on
password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget the password for the computer, you can clear that password so you can gain access to the
information on the computer by resetting the password jumper.
CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to
back up the computer CMOS settings before resetting them in case they are needed later. Back up is
easily done through Computer Setup. See Computer Setup (F10) Utility on page 54 for information on
backing up the CMOS settings.

1.
Shut down the operating system properly, then turn off the computer and any external devices,
and disconnect the power cord from the power outlet.
2.
With the power cord disconnected, press the power button again to drain the system of any
residual power.
WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be
sure to disconnect the power cord from the wall outlet, and allow the internal system components
to cool before touching.
CAUTION: When the computer is plugged in, the power supply always has voltage applied to
the system board even when the unit is turned off. Failure to disconnect the power cord can result
in damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment.
Before beginning these procedures, ensure that you are discharged of static electricity by briefly
touching a grounded metal object. See the Safety & Regulatory Information guide for more
information.
3.

HP PC Hardware Diagnostics
To help troubleshoot and diagnose failures, use the UEFI-based hardware diagnostic solution that HP
includes on all products. This tool can even be used if the computer will not boot to the operating
system.
Why run HP PC Hardware Diagnostics
The HP PC Hardware Diagnostic tools simplify the process of diagnosing hardware issues and expedite
the support process when issues are found. The tools save time by pinpointing the component that
needs to be replaced.
●
Isolate true hardware failures: The diagnostics run outside of the operating system so they
effectively isolate hardware failures from issues that may be caused by the operating system or
other software components.
●
Failure ID: When a failure is detected that requires hardware replacement, a 24-digit Failure ID
is generated. This ID can then be provided to the call agent, who will either schedule support or
provide replacement parts.
How to access and run HP PC Hardware Diagnostics
You can run the diagnostics from one of three places, depending on your preference and the health of
the computer.
1.
Turn on the computer and press Esc repeatedly until the BIOS Boot Menu appears.
2.
Press F2 or select Diagnostics (F2).
Pressing F2 signals the system to search for the diagnostics in the following locations:
116
a.
A connected USB drive (to download the diagnostics tools to a USB drive, see the instructions
in Downloading HP PC Hardware Diagnostics to a USB device on page 117)
b.
The hard disk drive
c.
A core set of diagnostics in the BIOS (for memory and hard disk drive) that are accessible
only if the USB or hard disk drive versions are not detected

Statement of Volatility
HP confirms that Intel-based HP 200 G1 MT personal computer contains DDR RAM volatile memory
(memory amount depends on the customer configuration). In addition, the motherboard in the condition
originally shipped without subsequent modification or the addition or installation of any applications,
features, or functionality, contain the following non-volatile memory: PCH Real Time Clock (RTC) battery
backed-up configuration memory (256 Bytes), DIMM Serial Presence Detect (SPD) configuration data
(256 Bytes per module, 128 Bytes programmable), and Serial Flash IC for System BIOS (64M Bits).
The volatile memory is cleared by removing power from the system for greater than 30 seconds. The
non-volatile memory on the motherboard is restored by following the steps below:
1.
Download the latest BIOS for this system and operating system off of the HP website.
2.
Follow the instructions on the website to flash the BIOS.
3.
Enter F10 setup.
4.
Select Default Setup > Reset Factory Settings as Default, and then select Apply
Defaults and Exit. Setup and Power-on password can be cleared by the BIOS Password Clear
jumper.
5.
Power down the system and remove the AC power card. The RTC and Super I/O battery backedup memory is cleared by removing the battery found on the motherboard, allowing the board to
sit for greater than 60 seconds, and then replacing the battery.
The DIMM SPD EEPROM is not readily available to the user, however there are tools publicly available
to read and write this part. To eliminate the possibility that it could contain sensitive information,
remove the DIMMs or use one of these tools.
