Installing Components 57

Replacing the battery

The battery provides power for the system real-time clock and CMOS

RAM, which holds the system configuration information.

Restart the computer and start the BIOS Setup program by pressing

when you are prompted to do so.

Write down the CMOS values from the Main Setup screen so you can

re-enter them after you replace the battery. (For more information

about the setup program, see “About the BIOS setup utility” on

page 62.)

Turn off the system and disconnect the power cord.

Open the case (“Opening the system” on page 3), observing the static

electricity precautions in “Static electricity precautions” on page 2.

Locate the battery on the system board (see Figure 7 on page 14). The

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

Gently pull the battery from its socket, and press the new battery in the

socket with the positive pole (+) up. Be sure you have pressed the

battery down far enough for it to contact the base of the socket.

Close the case, as described in “Closing the system” on page 8.

Reconnect the power cord and turn on the system.

Enter the BIOS Setup program and verify that the system

configuration is correct using the data you recorded in Step 2.

If the CMOS data is not correct, change the information in the setup

screens as necessary.

To replace the battery

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.
