Replacing the battery
The battery provides power for the system real-time clock and CMOS memory,
which holds the system configuration information.
If your battery is failing you may notice the server clock slowing down and
giving you the incorrect time.
Open the BIOS Setup utility and write down all the values in the various
menus before replacing the battery. Replacing the battery resets the BIOS Setup
utility to its default values.

To replace the battery:

1Restart the computer and start the BIOS Setup utility.
2Write down the CMOS values from each tab in the BIOS Setup utility so
you can reenter them after you replace the battery. For more information
