Battery
A 3.0-V CR2032 lithium coin-cell battery installed on the system board
maintains system configuration, date, and time information in a special
section of memory.
The operating life of the battery can extend up to ten years. The battery
may need replacing if an incorrect time or date is displayed during the boot
routine along with a message such as:
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, reenter the time and
date through system setup and exit the program properly 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. If the date and time are not correct in system setup, replace
your battery.
