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 your system clock slowing down and
giving you the incorrect time. If so, 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:
1 Restart the computer and start the BIOS Setup utility by pressing F1 when
you are prompted to do so.
2 Write down the CMOS values from the Main, Advanced, Security, Server
and
Boot menus so you can reenter them after you replace the battery.
For more information about the BIOS Setup utility program, see “Using
the BIOS Setup Utility” on page 67.
3 Turn off the computer, disconnect the power cord, modem cord (if
installed), and all external peripheral devices.
Warning There is a danger of explosion if the battery is incorrectly
replaced. Replace the battery only with the same or
equivalent type recommended by the manufacturer.
Dispose of used batteries according to the manufacturer’s
