4-12 Maintenance and Troubleshooting

3.

Locate the battery and its socket on the system board (see Figure 4-2).

Figure 4-2 Locating the Battery

4.

Use fingers to carefully pull the battery up until it is clear to slide the battery out
of the socket.

WARNING:

The battery can explode if it is

incorrectly replaced or improperly discarded.
Use only the same battery or an equivalent type
recommended by the manufacturer when
replacing the battery.

Lithium acts as a catalyst when exposed to water
and causes spontaneous combustion on contact.
Discard used batteries according to the
manufacturer’s instructions.

5.

With the positive (+) side facing up, press the new battery into the socket.

6.

Replace the system access cover.

7.

Connect external peripherals and power cables.

8.

Run Setup to reconfigure system parameters (see Section 2).
