6 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.
Generating static The following table shows that: ● Different activities generate different amounts of static electricity. ● Static electricity increases as humidity decreases.
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. To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be connected and fit snugly into the banana plug connector on the grounding mat or workstation.
● 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 ● Transparent metallized shielding bags ● Transparent shielding tub
● 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 ● 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 ● Tamper-resistant T-15 wrench Screws The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of different lengths.
● If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard drive while the computer is on or in standby mode. ● Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector. ● 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.
SATA hard drive cables 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.
7 Removal and replacement procedures Adherence to the procedures and precautions described in this chapter is essential for proper service. After completing all necessary removal and replacement procedures, run the Diagnostics utility to verify that all components operate properly. NOTE: Not all features listed in this guide are available on all computers. Serviceability features The computers include features that make them easy to upgrade and service.
Access panel Description Spare part number Access panel 674373-001 1. Prepare the computer for disassembly (Preparation for disassembly on page 32). 2. Loosen the captive Torx screw (1) on the back panel that secures the panel to the computer. 3. Slide the side panel toward the back (2), and then pull it away from the computer. NOTE: Lay the computer on its side to install internal parts. To replace the access panel, reverse the removal steps.
Front bezel Description Spare part number Front bezel 751588-001 1. Prepare the computer for disassembly (Preparation for disassembly on page 32). 2. Remove the access panel (Access panel on page 33). 3. Press outward on the three latches (1) on the right side of the bezel. 4. Rotate the right side of the bezel off the chassis, and then remove the bezel from the chassis (2). To reinstall the front bezel, reverse the removal procedure.
Memory Description Spare part number Memory module, 4-GB 671613-001 Memory module, 2-GB 671612-001 The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs). DDR3/DDR3L-SDRAM UDIMMs The system board offers two memory sockets. 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 8-GB of memory.
Populating DIMM sockets Populate the DIMM sockets in the following order: XMM2, XMM1 or Channel A, Channel B. Description Socket Color XMM1 socket, Channel A Blue 2 XMM2 socket, Channel A (populate first) Blue 1 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 DIMMs are installed.
be balanced so that the largest amount of memory is spread between the two channels. If one channel will have more memory than the other, the larger amount should be assigned to Channel A. For example, if you are populating the sockets with one 4-GB DIMM, and one 2-GB DIMM, Channel A should be populated with the 4-GB DIMM, and Channel B should be populated with the 2-GB DIMM. With this configuration, 4 GB will run as dual channel and 2 GB will run as single channel.
4. Open both latches (1) of the memory module socket , and remove the memory module from the socket (2). To install a memory module, reverse the removal procedures. 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 XMM1 socket. To create a dual-channel memory configuration, the memory capacity of Channel A must equal the memory capacity of Channel B.
2. Grasp the cable end of the connector and pull it straight up (2). CAUTION: Always pull the connector - NEVER pull on the cable. Pulling on the cable could damage the cable and result in a failed power supply. Cable connections System board connectors are color-coded to make it easier to find the proper connection.

D Troubleshooting without diagnostics This chapter provides information on how to identify and correct minor problems, such as USB devices, hard drive, optical drive, graphics, audio, memory, and software problems. If you encounter problems with the computer, refer to the tables in this chapter for probable causes and recommended solutions.
● If you recently installed new software, uninstall the software and see if the computer functions properly. ● Boot the computer to the Safe Mode to see if it will boot without all of the drivers loaded. When booting the operating system, use “Last Known Configuration.” ● Refer to the comprehensive online technical support at http://www.hp.com/support. ● Refer to Helpful hints on page 76 in this guide.
● Check the Power LED on the front of the computer to see if it is flashing red. The flashing lights are error codes that will help you diagnose the problem. Refer to Appendix A, POST Error Messages on page 62 for more information. ● Turn up the brightness and contrast controls of the monitor if the monitor is dim. ● Press and hold any key. If the system beeps, then the keyboard should be operating correctly. ● Check all cable connections for loose connections or incorrect connections.
Solving general problems You may be able to easily resolve the general problems described in this section. If a problem persists and you are unable to resolve it yourself or if you feel uncomfortable about performing the operation, contact an authorized dealer or reseller. WARNING!
