System Components

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 setup utility screens 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 program by pressing

F1 when you are prompted to do so.

2 Write down the CMOS values from the Main BIOS Setup utility screens

so you can reenter them after you replace the battery. For more

information about the BIOS Setup utility program, see page 47.

Turn off the computer, disconnect the power cord, modem cord (if

installed), and all external peripheral devices.

4 Open the case (see “Opening the case” on page 17), observing the “Static

electricity precautions” on page 15.

5 Remove the system board (see “Removing the system board” on page 31)

6 Locate the battery on the system board (see “System board” on page 5.)

The battery is circular and has the positive pole mark (+) on the top.

Caution 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

instructions.
