4 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 6.0 Gb/s cable as it is fully backwards compatible with the SATA 1.5 Gb/s drives. Current HP desktop products ship with SATA 6.0 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.
5 Removal and replacement procedures: Microtower 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.

Memory Description Spare part number 8-GB, PC3-12800 689375-001 4-GB, PC3-12800 671613-001 2-GB, PC3-12800 671612-001 The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to two industry-standard DIMMs (model 400) or four industry-standard DIMMs (model 490) . These memory sockets are populated with at least one preinstalled DIMM.
Populating DIMM sockets (Model 400) There are two DIMM sockets on the system board, with one socket per channel. The sockets are labeled DIMM1 and DIMM3. Socket DIMM1 operates in memory channel B. Socket DIMM3 operates in memory channel A. The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed. NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior graphics performance.
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.
3. Open both latches of the memory module socket (1), and insert the memory module into the socket (2). NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. Populate the black DIMM sockets before the white DIMM sockets. For maximum performance, populate the sockets so that the memory capacity is spread as equally as possible between Channel A and Channel B. 4.
