CAUTION:
Before you begin any of the procedures in this section, follow the
safety instructions in the Product Information Guide.
NOTICE:
To prevent static damage to components inside your computer, discharge
static electricity from your body before you touch any of your computer’s electronic
components. You can do so by touching an unpainted metal surface on the
computer chassis.
A coin-cell battery maintains computer configuration, date, and time
information. The battery can last several years. If you have to repeatedly reset
time and date information after turning on the computer, replace the battery.

A new battery can explode if it is incorrectly installed. Replace the
battery only with the same or equivalent type recommended by the manufacturer.
Discard used batteries according to the manufacturer’s instructions.
