About the Battery
A coin-cell battery maintains computer configuration, date, and time information. The battery can last several years.
The battery may need replacing if you have repeatedly reset the time and date information after turning on the computer 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
or
Strike the F1 key to continue,
F2 to run the setup utility
To determine whether you need to replace the battery, re-enter the time and date in system setup and exit the program to save the information. Turn off your
computer and disconnect it from the electrical outlet for a few hours; then reconnect the computer, turn it on, and enter system setup (see Entering System
Setup). If the date and time are not correct in system setup, replace the battery.
You can operate your computer without a battery; however, without a battery, the configuration information is erased if the computer is turned off or
unplugged from the electrical outlet. In this case, you must enter system setup (see Entering System Setup) and reset the configuration options.
Removing the Battery
1. If you have not already done so, make a copy of your configuration information found in system setup (see System Setup).
1. Follow the procedures in Before You Begin.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your
computer's electronic components. You can do so by touching an unpainted metal surface on the computer.
