Replacing the Battery

To replace the battery, you must first remove the side cover.
When your computer is turned off, a lithium battery maintains the current time-of-day clock and
the values in CMOS RAM current. Figure 12 shows the location of the battery.
The battery should last about seven years. When the battery begins to die, it loses voltage; when
the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS RAM
(for example, the date and time) might not be accurate. Replace the battery with an equivalent
one.
WARNING
Danger of explosion if the battery is incorrectly replaced. Replace only with the same or
equivalent type recommended by the equipment manufacturer. Discard used batteries according
to manufacturer's instructions.
To replace the battery, follow these steps:
1. Ensure that the safety precautions stated for removing the side cover has been observed.
2. Locate the battery on the motherboard.
3. With a medium flat-bladed screwdriver, gently pry the battery free from its connector. Note
the orientation of the "+" and "-" on the battery.
4. Install the new battery in the connector, orienting the "+" and "-" correctly.
5. Reinstall and reconnect any parts you removed or disconnected to reach the battery.
6. Use the Configuration/Setup Utility program to set the date and time and any passwords.
