Battery: Dell™ OptiPlex™ GX100 System User's Guide
Overview
A 3.0-volt (V) CR2032 coin-cell battery installed on the system board maintains system configuration, date, and time information in a special
section of memory.
The operating life of the battery can extend up to ten years. The battery may need replacing if an incorrect time or date is displayed during the boot
routine along with a message such as:
Time-of-day not set - please run SETUP program
or
Invalid configuration information -
please run SETUP program
or
Strike the F1 key to continue,
F2 to run the setup utility
To determine whether you need to replace the battery, reenter the time and date through
System Setup
and exit the program properly to save the
information. Turn off your system and disconnect it from the electrical outlet for a few hours; then reconnect and turn on your system. Enter System
Setup. If the date and time are not correct in System Setup, replace your battery.
You can operate your system without a battery; however, without a battery, the system configuration information is erased if the system is turned off
or unplugged from the electrical outlet. In this case, you must enter System Setup and reset the configuration options.

To replace the system battery, perform the following steps:
1. If you have not already done so, make a copy of your system configuration information in

.
If the settings are lost while you are replacing the battery, refer to your written or printed copy of the system configuration information to

NOTICE: If you pry the battery out of its socket with a blunt object, be careful not to touch the system board with the object.
Make certain that the object is inserted between the battery and the socket before you attempt to pry out the battery. Otherwise,
you may damage the system board by prying off the socket or by breaking circuit traces on the system board.
Pry the battery out of its socket with your fingers or with a blunt, nonconductive object, such as a plastic screwdriver.
4. Install the new battery.
