Replacing the battery (all machine types)
The 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. 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 251 for information
about replacing and disposing of the battery.
To change the battery:
1. Turn off the computer and all attached devices.
2. Remove the cover. See “Removing the cover” on page 30.
3. Locate the battery. See “Identifying parts on the system board (all machine
types)” on page 38.
4. If necessary, remove any adapters that impede access to the battery. See
“Replacing adapters” on page 39 for more information.
5. Remove the old battery.
6. Install the new battery.
7. Replace any adapters that were removed to gain access to the battery. See
“Replacing adapters” on page 39 for instructions for replacing adapters.
8. Replace the cover, and plug in the power cord. See “Replacing the cover and
connecting the cables” on page 63.
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.
