A 3.0-V CR2032 coin-cell battery mounted in a system board socket (see Figure 2-4)

maintains system configuration, date, and time information. The battery can last sev-

eral years.

If the battery expires, the system loses the system configuration information when-

ever it is disconnected from power. If you have to repeatedly reset this information

after turning on the system, replace the battery.

To replace the system battery with another CR2032 coin-cell battery, follow these

steps.

restore the correct settings later. Refer to Appendix B, “System Setu p P rogram ,”
