Service Considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and

assembly of the computer.

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

Screws

The screws used in the computer are not interchangeable. They may have standard or metric threads

and may be of different lengths. If an incorrect screw is used during the reassembly process, it can

damage the unit. HP strongly recommends that all screws removed during disassembly be kept with

the part that was removed, then returned to their proper locations.

CAUTION: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard

drives only.

CAUTION: As each subassembly is removed from the computer, it should be placed away from the

work area to prevent damage.

Hard Drives

Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This

applies to failed drives as well as replacement spares.

●

If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective

packaging and label the package “Fragile: Handle With Care.”

●

Do not remove hard drives from the shipping package for storage. Keep hard drives in their

protective packaging until they are actually mounted in the CPU.

● Avoid dropping drives from any height onto any surface.

●

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. For more information about preventing electrostatic

damage, refer to

Electrostatic Discharge Information on page 35

●

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.
