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.
