Replacing the Battery
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in
the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body
before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface
on the computer.
A coin-cell battery maintains computer configuration, date, and time information. The battery can last several years.
The battery may need replacing if you have repeatedly reset the time and date information after turning on the computer or if
one of the following messages appear:
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 in system setup and exit the program to
save the information. Turn off your computer and disconnect it from the electrical outlet for a few hours; then reconnect the
computer, turn it on, and enter system setup. If the date and time are not correct in system setup, replace the battery.
You can operate your computer without a battery; however, without a battery, the configuration information is erased if the
computer is turned off or unplugged from the electrical outlet. In this case, you must enter system setup and reset the
configuration options.
CAUTION: A new battery can explode 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.
1. Follow the procedures in " Before You Begin ."
2. Locate the battery socket.
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. Ensure 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.
3. Remove the battery by carefully prying it out of its socket with your fingers or with a blunt, nonconducting object such
as a plastic screwdriver.
4. Insert the new battery into the socket with the side labeled "+" facing up, and snap the battery into place.
