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

appears:

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 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.

To replace the battery:

1. Locate the battery socket. For the Dell Precision 450 computer, see "System Board Components" or for the Dell Precision 650 computer, see "System

Board Components" or see the system board label inside your computer.

2. Remove the battery by carefully prying it out of its socket with your fingers or with a blunt, nonconducting object such as a plastic screwdriver.

3. Insert the new battery into the socket with the side labeled "+" facing up, and snap the battery into place.

4. Close the computer cover, and plug your computer and devices into electrical outlets.

5. Enter system setup and restore the settings.

6. Properly dispose of the old battery. For more information see your System Information Guide.
