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.
● Always be properly grounded when touching a sensitive component or assembly. ● Avoid contact with pins, leads, or circuitry. ● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam. Personal Grounding Methods and Equipment Use the following equipment to prevent static electricity damage to equipment: ● Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground cords.
● Conductive bins and other assembly or soldering aids ● Conductive foam ● Conductive tabletop workstations with ground cord of one-megohm +/- 10% resistance ● Static-dissipative table or floor mats with hard tie to ground ● Field service kits ● Static awareness labels ● Wrist straps and footwear straps providing one-megohm +/- 10% resistance ● Material handling packages ● Conductive plastic bags ● Conductive plastic tubes ● Conductive tote boxes ● Opaque shielding bags ● Transparen
● Never cover the ventilation slots on the monitor with any type of material. ● Install or enable power management functions of the operating system or other software, including sleep states. Routine Care General Cleaning Safety Precautions 1. Never use solvents or flammable solutions to clean the computer. 2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. 3.
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys. ● Visible debris underneath or between the keys may be removed by vacuuming or shaking. ● Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys. ● If you remove a key, use a specially designed key puller to prevent damage to the keys.
Tools and Software Requirements To service the computer, you need the following: ● Torx T-15 screwdriver (HP screwdriver with bits, PN 161946-001) ● Torx T-15 screwdriver with small diameter shank (for certain front bezel removal) ● Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver) ● Phillips #2 screwdriver ● Diagnostics software ● HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamperresistant bits (Smart Cover FailSafe Key, PN 16652
● Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector. For more information about preventing electrostatic damage, refer to Electrostatic Discharge Information on page 24 ● Do not use excessive force when inserting a drive. ● Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields such as monitors or speakers.
5 Removal and Replacement Procedures Convertible Minitower (CMT) Chassis Adherence to the procedures and precautions described in this chapter is essential for proper service.

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.
Cable Connections System board connectors are color-coded to make it easier to find the proper connection.
Installing Additional Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 16-GB of memory configured in a high-performing dual channel mode.
Populating DIMM Sockets There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A. Sockets XMM3 and XMM4 operate in memory channel B.
Channel A. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as dual channel and 1-GB will run as single channel. ● In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
4. Open both latches of the memory module socket (1), and insert the memory module into the socket (2). Figure 5-7 Installing a DIMM NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. A DIMM must occupy the black XMM1 socket. Populate the DIMM sockets in the following order: XMM1, XMM3, XMM2, then XMM4.

Replace the computer cover or access panel. 6. Reconnect the external devices. 7.
F Drive Protection System (DPS) The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in some computers. DPS is designed to help diagnose problems that might result in unwarranted hard drive replacement. When these systems are built, each installed hard drive is tested using DPS, and a permanent record of key information is written onto the drive. Each time DPS is run, test results are written to the hard drive.
Accessing DPS Through Computer Setup When the computer does not power on properly you should use Computer Setup to access the DPS program. To access DPS, perform the following steps: 1. Turn on or restart the computer. 2. When the F10 Setup message appears in the lower-right corner of the screen, press the F10 key. NOTE: If you do not press the F10 key while the message is displayed, you must turn the computer off, then on again, to access the utility.
G Computer Diagnostic Features Hewlett-Packard Vision Diagnostics NOTE: HP Vision Diagnostics is included on CD with some computer models only. The Hewlett-Packard Vision Diagnostics utility allows you to view information about the hardware configuration of the computer and perform hardware diagnostic tests on the subsystems of the computer. The utility simplifies the process of effectively identifying, diagnosing, and isolating hardware issues.
4. Turn on the computer. The system will boot into HP Vision Diagnostics. NOTE: If the system does not boot to the CD in the optical drive or to the USB flash drive, you may need to change the boot order in the Computer Setup (F10) utility. Refer to the Computer Setup (F10) Utility Guide for more information. 5. At the boot menu, select either the HP Vision Diagnostics utility to test the various hardware components in the computer or the HP Memory Test utility to test memory only.
Test Tab The Test tab allows you to choose various parts of the system to test. You can also choose the type of test and testing mode. There are three types of tests to choose from: ● Quick Test—Provides a predetermined script where a sample of each hardware component is exercised. You may further modify which of the Quick tests are executed by selecting or deselecting individual tests in the hardware component check list.
The Status tab also shows: ● The devices being tested ● The test status (running, waiting, passed, or failed) of each device being tested ● The overall test progress of all devices being tested ● The test progress for each device being tested ● The elapsed test times for each device being tested History Tab The History tab contains information on past test executions.
Help Tab The Help tab contains a Vision Help section, and a Test Components section. This tab includes search and index features. You may also review the HP End User License Agreement (EULA), as well as the HP Vision Diagnostic application version information on this tab. The Vision Help section contains information on the major functions of Hewlett-Packard Vision Diagnostics.
8. Click the Hewlett-Packard Vision Diagnostics link. 9. Click the Download button. NOTE: The download includes instructions on how to create the bootable CD or the bootable USB flash drive. Protecting the Software To protect software from loss or damage, you should keep a backup copy of all system software, applications, and related files stored on the hard drive. See the operating system or backup utility documentation for instructions on making backup copies of data files.
H Backup and Recovery Windows 7 – Backup and Recovery To protect your information, use Windows® Backup and Restore to back up individual files and folders, back up your entire hard drive (select models only), create system repair discs (select models only), or create system restore points. In case of system failure, you can use the backup files to restore the contents of your computer.
● Save customized settings that appear in a window, toolbar, or menu bar by taking a screen shot of your settings. The screen shot can be a time-saver if you have to reset your preferences. To create a screen shot: 1. Display the screen you want to save. 2. Copy the screen image: To copy only the active window, press alt+fn+prt sc. To copy the entire screen, press fn+prt sc. 3. Open a word-processing document, and then select Edit > Paste. The screen image is added to the document. 4.
NOTE: If you are unable to boot (start up) your computer and you cannot use the system repair discs you previously created (select models only), you must purchase a Windows 7 operating system DVD to reboot the computer and repair the operating system. For additional information, refer to the “Using a Windows 7 operating system DVD (purchased separately)” section in this guide. Using the Windows recovery tools To recover information you previously backed up, follow these steps: 1.
Using f11 CAUTION: Using f11 completely erases hard drive contents and reformats the hard drive. All files you have created and any software installed on the computer are permanently removed. The f11 recovery tool reinstalls the operating system and HP programs and drivers that were installed at the factory. Software not installed at the factory must be reinstalled. To recover the original hard drive image using f11, follow these steps: 1. If possible, back up all personal files. 2.
Windows Vista – Backup and Recovery To protect your information, use the Backup and Restore Center to back up individual files and folders, back up your entire hard drive (select models only), or create system restore points.
