Replacing the system battery
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 according to
local hazardous materials regulations.
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:

2 During the restart, press and hold the F1 key. The main menu of the
BIOS Setup utility opens.
3 Write down all the values in the menus and submenus, then exit from the
utility.

5 Remove the side panel by following the instructions in “Removing the side
panel” on page 12.

case, place it on a towel or other non-abrasive surface.
