Replacing the battery
Your computer has a special type of memory that maintains the date, time, and
settings for built-in features, such as serial-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 “Safety notices (multi-lingual translations)” on page 7 for information
about replacing and disposing of the battery.
To change the battery:
1.
Turn off the computer and disconnect the power cord from the electrical outlet
and from the computer.
2. Open the computer cover. See “Opening the cover” on page 94.
3. Access the system board. See “Accessing system board components and drives”
on page 96.
4. Locate the battery. See “System board connectors and components” on page 93.
5. Remove the old battery.
6. Install the new battery.
Note: When the computer is turned on for the first time after battery
replacement, an error message might be displayed. This is normal after
replacing the battery.
7. Go to “Completing the FRU replacement” on page 123.
