date information after turning on the system, or the following messages appear, replace the battery. See "
Replacing the Battery " in "Installing System
Options."

You can operate your system without a battery; however, without a battery, the configuration information is erased if the system is turned off or unplugged
from the electrical outlet. In this case, you must enter the System Setup program and reset the configuration options.
Action
1. Re-enter the time and date through the System Setup program. See "Using the System Setup Program" in your User's Guide.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system.
Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the
computer and protecting against electrostatic discharge.
NOTE: If the system is turned off for long periods of time (for weeks or months), the NVRAM may lose its system configuration information. This situation
is caused by a defective battery.
