-Brightness(typical): LCD brightness varies as follows, depending on both setting in TSETUP and AC/Battery operation. BIOS recognizes either AC operation or battery operation at power on(in Boot mode and Resume mode). Therefore, if the machine is turned on in AC operation and if it’s changed to battery operation, BIOS can’t recognize that, remaining with LCD brightness in AC operation, which causes to decrease battery life.
