Changing the battery
Your computer has a special type of memory that maintains the date, time, and
settings for built-in features, such as parallel-port assignments (configuration). A
battery keeps this information active when you turn off the computer.
The battery normally requires no charging or maintenance throughout its life;
however, no battery lasts forever. If the battery fails, the date, time, and
configuration information (including passwords) are lost. An error message is
displayed when you turn on the computer.
Refer to “Lithium battery notice” on page x for information about replacing and
disposing of the battery.
To change the battery:
1. Open the computer cover. See “Opening the cover” on page 21.
2. While holding the left rear of the computer chassis down, pull upward on the
handle provided to remove the PCI riser and any adapters that are currently
installed.
3. Locate the battery. See “Identifying parts on the system board” on page 23.
4. Remove the old battery.
