Dell NX046 manual Replacing the Battery, 177

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 the system setup program (see "System Setup" on page 89). 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 the system setup program (see "System Setup" on page 89) and reset the configuration options.

1If you have not already done so, write down the configuration information found in system setup (see "System Setup" on page 89).
