Replacing the Battery

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

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, 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. Shut down the computer through the Start menu.

2. Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut

down your computer, turn them off now.

3. Disconnect any telephone or telecommunication lines from the computer.

4. Disconnect your computer and all attached devices from electrical outlets, and then press the power button to ground the system board.

5. If you have installed a padlock through the padlock ring on the back panel, remove the padlock.

6. Open the computer cover.

7. Locate the battery socket labeled BATTERY.

8. 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.

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

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the System Information Guide.

NOTE: If you have not already done so, make a copy of your configuration information, found in system setup.

NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.

10. Close the computer cover and connect your computer and devices to electrical outlets.

11. Enter system setup and restore the settings you recorded before beginning this procedure.

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