Screws
The screws used in the computer are not interchangeable. They could have standard or metric threads and
might be of dierent 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 and then returned to their proper locations.
IMPORTANT: As you remove each subassembly from the computer, place it away from the work area to
prevent damage.
Cables and connectors
Apply only the tension required to seat or unseat the cables during insertion or removal from the connector.
Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and
make sure that the cables are routed so that they cannot be caught or snagged by parts being removed or
replaced.
IMPORTANT: When servicing this computer, be sure to place cables in their proper location during the
reassembly process. Improper cable placement can damage the computer.
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 computer.
● Avoid dropping drives from any height onto any surface.
● If you are inserting or removing a hard drive, turn o the computer. Do not remove a hard drive while the
computer is on or in standby mode.
● Before handling a drive, make sure 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 elds
such as monitors or speakers.
