To view on the battery

Separate the battery and press the PUSH button inside the battery. The remaining battery charge (%) will be displayed.

Battery Warning

If the battery residual amount is 3~5%, the computer automatically shuts down after saving the data. The battery residual amount may vary depending on the computer model.

Battery Usage Time Information

A battery is an expendable supply, so when using it over a long time, the capacity/battery life is shortened. If the battery life is reduced to under half of its initial time, we recommend purchasing a new battery.

For long periods of not using the battery, keep the battery after discharging it. This extends the battery life time.

Extending the Battery Usage Time

Decreasing the LCD Brightness

Press the Fn + keys on the keyboard to decrease the LCD brightness to extend the battery usage time.

You can only use this function after installing Windows XP/ Windows Vista/Windows 7 Vista and installing the Easy Display Manager program with the system software media disk.

(Only for Windows XP/Windows Vista/Windows 7)
