Battery

The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime
of about three years. Observe the following warning and caution when replacing the battery.
CAUTION: Before removing the battery, back up the CMOS settings in case they are lost when the battery is
removed. To back up the CMOS settings, select the Save to Removable Storage option in Computer Setup
(F10) Utility.
NOTE: Do not dispose of batteries, battery packs, and accumulators with general household waste.

Cable management

Proper routing of the internal cables is critical to the operation of the workstation. Follow good cable
management practices when removing and installing components.
● Handle cables with care to avoid damage.
● Apply only the tension required to seat or unseat cables during insertion or removal from the connector.
● When possible, handle cables by the connector or pull-strap.
● Route cables in such a way that they cannot be caught or snagged by parts being removed or replaced.
● Keep cables away from direct contact with major heat sources, such as the heat sink. (Some air flow
guides have a cable guide that lets you route cables safely around the heat sink.)
● Do not jam cables on top of expansion cards or SODIMMs. Circuit cards and SODIMMs are not designed to
take excessive pressure.
Removal and replacement procedures are now available in videos on the HP website.
