Replacing the system battery
If the computer clock does not keep time or the settings in
the BIOS Setup utility are not saved when you turn off your
computer, replace the system battery. Use a battery of the
same size and voltage as the original battery that was in your
computer.
To replace the battery:
1 Restart your computer.
2 During the restart, press and hold the F1 key. The main
menu of the BIOS Setup utility opens.
3 Write down all values in the menus and submenus, then
exit from the utility.
4 Shut down your computer.
5 Remove the side panel by following the instructions in
“Opening and closing the case” on page 39.
6 Remove the drives from the optical and 3.5-inch drive
cage by following the instructions in “Replacing the
diskette drive” on page 41 or “Replacing the memory
card reader” on page 44.
Warning
Danger of explosion if battery is incorrectly replaced. Replace only with
the same or equivalent type recommended by the manufacturer. Dispose of
used batteries following the manufacturer’s instructions.
Caution
Any custom BIOS settings you have made will be lost when you remove
the system battery. All settings will return to their factory defaults.
