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:
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 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.

handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose in water or fire, or
expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the battery.
NOTE:
Batteries, battery packs, and accumulators should not be disposed of together with general household
waste. In order to forward them for recycling or proper disposal, please use the public collection system or
return them to HP.
SMART ATA drives
The Self Monitoring Analysis and Recording Technology (SMART)ATA drives for HP personal computers have
built-in drive failure prediction that warns the user or network administrator of an impending failure (crash) of
the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as reallocated
sector count, spin retry count, and calibration retry count. If the drive determines that a failure is imminent, it
generates a fault alert.
