Cables And Connectors; Hard Drives; Lithium Coin Cell Battery - HP dx2308 - Microtower PC Service & Reference Manual

Cables and Connectors

Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to
avoid damage. 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 ensure that the cables are routed in such a way that they cannot be caught or
snagged by parts being removed or replaced.
CAUTION:
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 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 29
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.
