2. Gently remove the battery from the battery holder and wait for one minute. (Or use a metal object like a screwdriver to touch the positive and negative terminals of the battery holder, making them short for 5 seconds.)

3. Replace the battery.

4. Plug in the power cord and restart your computer.

• Always turn off your computer and unplug the power cord before replacing the battery.

• Replace the battery with an equivalent one. Danger of explosion if the battery is replaced

with an incorrect model.

• Contact the place of purchase or local dealer if you are not able to replace the battery by yourself or uncertain about the battery model.

• When installing the battery, note the orientation of the positive side (+) and the negative side (-) of the battery (the positive side should face up).

• Used batteries must be handled in accordance with local environmental regulations.

Connects to the power status indicator on the chassis front panel . The LED is on when the system is operating. The LED keeps blinking when the system is in S1 sleep state. The LED is off when the system is in S3/S4 sleep state or powered off (S5).

• PW (Power Switch): Connects to the power switch on the chassis front panel. You may configure the way to turn off your system using the power switch (refer to Chapter 2, "BIOS Setup," "Power Management Setup," for more information).

• SPEAK (Speaker): Connects to the speaker on the chassis front panel. The system reports system startup status by issuing a beep code. One single short beep will be heard if no problem is detected at system startup. If a problem is detected, the BIOS may issue beeps in different patterns to indicate the problem. Refer to Chapter 5, "Troubleshooting," for information about beep codes.

• HD (IDE Hard Drive Activity LED) Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive is reading or writing data.

• RES (Reset Switch): Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer if the computer freezes and fails to perform a normal restart.

• NC: No connection
