Adjusting Brightness on the LED Backlit Thin-and-Light LCD

When a Dell Tablet-PC equipped with the LED backlit thin-and-light LCD

display is running on battery power, you can conserve power by setting the

display brightness to the lowest comfortable setting by pressing <Fn> and

the up- or down-arrow key on the keyboard.

NOTE: Brightness key combinations only affect the display on your Tablet-PC, not

monitors or projectors that you attach to your Tablet-PC or docking device. If your

Tablet-PC is connected to an external monitor and you try to change the brightness

level, the Brightness Meter may appear, but the brightness level on the external

device does not change.

You can press the following keys to adjust display brightness:

• Press <Fn> and the up-arrow key to increase brightness on the integrated

display only (not on an external monitor).

• Press <Fn> and the down-arrow key to decrease brightness on the

integrated display only (not on an external monitor).

NOTE: If your operating system display default is set to a specific value, you may

have to reset your manual selections after using sleep, standby, or hibernate mode.

Adjusting Brightness on the Dual-bulb (CCFL) LCD

The Dual-bulb LCD includes an integrated ambient light sensor (see "Front

View" on page 27).
