Battery: Dell™ OptiPlex™ GX115 System User's Guide
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 the system, turn it on, and 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.

CAUTION: There is a danger of the new battery
exploding if it is incorrectly installed. Replace the battery only with the same or
equivalent type recommended by the manufacturer. Discard used batteries according to the
manufacturer's instructions. |
To replace the system battery, perform the following steps:
- If you have not already done so, make a copy of
your system configuration information in System Setup.
If the settings are lost while you are replacing the battery, refer to your
written or printed copy of the system configuration information to restore the correct
settings.
- Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover."
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.
- Remove the battery by prying it out of its socket with your fingers or with a blunt,
nonconductive object, such as a plastic screwdriver.
See Figure 7 in "Inside Your
Computer" for the location of the battery.
- Install the new battery.
- Orient the battery with the side labeled "+" facing up (see
Figure 1).
- Insert the battery into the socket, and snap it into place.
