WARNING!
battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose of
in water or fire, or expose it to temperatures higher than 140°F (60°C). Do not attempt to recharge the
battery.
NOTE: Do not dispose of batteries, battery packs, and accumulators with general household waste.
To forward them to recycling centers or proper disposal, use the public collection system or return
them to HP, their authorized partners, or their agents.

SATA hard drives

The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an
impending failure or 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.

Data transfer rate
Always use an HP-approved SATA 6.0 Gbps cable because it is fully backwards compatible with the
SATA 1.5 Gbps drives. Current HP desktop products ship with SATA 6.0 Gbps 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. 1 8 in) radius.
The SATA data cable is a thin, seven-pin cable designed to transmit data for only a single drive.

Cable management

Always follow good cable management practices when working inside the computer.
● Keep cables away from major heat sources like the heat sink.
●
Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the
parts are moved.
● When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases can damage the wires.
