Claims23
An apparatus comprising:
- a processor;
- a plurality of backlight lamps, wherein the backlight lamps illuminate a display screen;
- a medium storing instructions adapted to be executed by the processor to perform a method, the instructions comprising:
- instructions to determine that a first predetermined amount of power is remaining in a battery;
- instructions to reduce a full sized backlit area of the display screen by a first percentage, wherein the first percentage is less than 100% and greater than 0%, and wherein reducing is by turning off a portion of the plurality of backlight lamps in response to the determination that the first predetermined amount of power remains;
- and
- instructions to resize an image to fit in the reduced backlit area on the display screen in response to the determination that the first predetermined amount of power remains.

A system comprising:
- a battery;
- a processor;
- a plurality of backlight lamps, wherein the backlight lamps illuminate a display screen;
- a lamp controller to reduce a portion of a backlit area of the display screen;
- and
- a medium storing instructions adapted to be executed by the processor to perform a method, the method comprising:
- determining that a first predetermined amount of power is remaining in the battery;
- reducing a fall sized backlit area of the display screen by a first percentage wherein the first percentage is less than 100% and greater than 0%, and wherein reducing is by turning off a portion of the plurality of backlight lamps in response to the determination that the first predetermined amount of power remains;
- and
- resizing an image to fit in the reduced backlit area on the display screen in response to the determination that the first predetermined amount of power remains.
