System Battery
A coin-cell battery maintains system 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.
The battery may need replacing if you have repeatedly reset the time and date information after turning on the system or if one of the following messages
appear:
Time-of-day not set - please run SETUP program
or
Invalid configuration information -
please run SETUP program
To determine whether you need to replace the battery, see "
Troubleshooting the System Battery
" in "Troubleshooting Your System."
You can operate your system without a battery; however, without a battery, the configuration information is erased if the system is turned off or unplugged
from the electrical outlet. In this case, you must enter the System Setup program and reset the configuration options.
