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 see an error message when you turn on or reset your computer. Contact your Authorized Epson Servicer or Epson Accessories to get a replacement battery or to install the new battery for you. If you want to replace the battery yourself, follow the instructions in this section.

N o t e

When the battery loses power, your computer loses the information stored in the CMOS RAM and the time stored in the real-time clock. After you replace the battery, run the SETUP program as described in Chapter 2 to reconfigure your system and set the time and date.
