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.
