CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
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 chassis.
A coin-cell battery maintains computer configuration, date, and time information. The battery can last several years.

Time-of-day not set - please run SETUP program
or
Invalid configuration information -
please run SETUP program
or

F2 to run the setup utility
To determine whether you need to replace the battery, reenter 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. 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 and reset the configuration options.
