Changing The Battery - IBM 6826 Hardware Maintenance Manual

See the following illustration for cable lock installation.

Changing the battery

Type 6826, 8317, 8318, 8319 computers have 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 the
computer is turned off.
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 information" on page 109 for information about replacing and
disposing of the battery.
To change the battery:
1. Refer to "Identifying parts on the system board" on page 23 and locate the
battery.
2. Remove the PCI riser and any cables that impede access to the battery.
3. Remove the old battery.
