Replacing the Battery
CAUTION: Before you begin this procedure, follow the safety instructions

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.
CAUTION: 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.
To replace the battery:
1
Record all the screens in system setup (see page 106) so that you can restore the
correct settings in step 12.
2
Shut down the computer through the Start menu.
3
Ensure that your computer and attached devices are turned off. If your computer and
attached devices did not automatically turn off when you shut down your computer,
turn them off now.
