System Introduction 1-23

The following processes are the basic methods used to implement the LCD brightness AutoDim.

1. If the original brightness is over 75% and the AC power is on-line, the BIOS will change the

brightness to 75% after the AC power is off-line.

2. If the original brightness is below 75%, the brightness maintains the same level even if the AC

power is off-line.

3. If the brightness is already changed by the hotkey under DC power, it will not be changed after

the AC power is plugged in.

4. If the brightness is not changed by the hotkey under DC power, the brightness will be changed

back to the old setting — the previous brightness parameter under AC power.

5. If the previous brightness parameter does not exist, the brightness will not be changed in

process 4.
