Replacing the Battery
Your computer comes with a 3.6 volt lithium battery that
provides power for the real-time clock and the CMOS RAM.
The real-time clock keeps track of the time for your
computer, and the CMOS RAM stores the information about
your system configuration that was saved by the SETUP
program.
This battery lasts approximately three to five years. If it loses
power, you will see an error message when you turn on or
reset your computer. Contact your dealer to obtain a
replacement battery pack. Your dealer can also install the
battery for you. If you want to replace the battery yourself,
you can follow the instructions in this section.
Note
When the battery runs out, your computer loses the
information stored in the CMOS RAM and the time stored
in the real-time clock. After you replace the battery, you
must run the SETUP program to reconfigure your system
and set the real-time clock.
