General Precautions
LCD
Over a period of time, and depending on the usage of the computer, the
brightness of the LCD screen will deteriorate. This is an intrinsic
characteristic of LCD technology. Maximum brightness is only available
when operating in AC power mode. Screen will dim when the computer is
operated on battery power and you may not be able to increase the
brightness of the screen.
