Replacing the Battery
The system battery is a 3.0-V, coin-cell battery that maintains system configuration, date, and
time information in a special section of memory when you turn off the system. The operating
life of the battery ranges from 2 to 5 years, depending on how you use the system (for example,
if you keep the system on most of the time, the battery gets little use and thus lasts longer). You
may need to replace the battery if an incorrect time or date is displayed during the boot routine.
You can operate the system without a battery; however, the system configuration information
maintained by the battery in NVRAM is erased each time you remove power from the system.
Therefore, you must reenter the system configuration information and reset the options each
time the system boots until you replace the battery.
To replace the battery, perform the following steps.
1.
Turn off the system, including any attached peripherals, and disconnect the system from the
electrical outlet.
2.
Open the system doors.
3.
Remove the system battery. The battery is located on the system board next to the fan
connectors. You can pry the system battery out of its socket with your fingers or with a
blunt, nonconducting object such as a plastic screwdriver.
4.
Install the new system battery with the side labeled “+” facing up (see Figure 4-9 ).
CAUTION :
Before you perform this procedure, you must turn off the system and
disconnect it from its power source.
DANGER : A new battery may explode if it is installed incorrectly. Replace the battery only
with the same or equivalent type recommended by the manufacturer. Discard used batteries
according to the manufacturer's instructions.
