48 Maintaining and Troubleshooting the Gateway ALR 8300 Server
It may be necessary to reconfigure your system after installing some
expansion cards. You may also need to install software that came with the
card. Check the card documentation for additional information.
Replacing the lithium battery
The lithium battery provides power for the system real-time clock and
CMOS RAM, which holds the system configuration information.
1.
Restart the computer and start the BIOS Setup program by pressing
F
1
when you are prompted to do so.
2.
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 “Using the BIOS Setup Utility” on
page 54.)
3.
Turn off the system and disconnect the power cord.
4.
Open the case, observing the ESD precautions in “Static electricity
precautions” on page 2.
5.
Locate the battery on the system board. The battery is circular and has
the positive pole mark (+) on the top, see Figure 7 on page 12.
6.
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 touch the base of the socket.
7.
Close the case, as described in “Closing the system” on page 7.
8.
Reconnect the power cord and turn on the system.
9.
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 and local laws.
Important!
If the CMOS has become
corrupted, the system may
turn on when power is first
applied. Because removing
the battery removes the
power source that supports
the CMOS memory, the
system will turn on when
power is applied after the
new battery is installed.
