similar to one of the following:
Time-of-day not set - please run SETUP programs
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 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.

unplugged from the electrical outlet. In that case, you must enter system setup and reset the configuration options.
