Using the Display

Adjusting Brightness

When a Dell™ computer is running on battery power, you can conserve power

by setting the 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 portable

computer, not monitors or projectors that you attach to your portable computer or

docking device. If your computer 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).

Using the Ambient Light Sensor

The ambient light sensor is located on the bottom of the computer display

panel. The ambient light sensor detects available environmental light and

automatically increases or decreases the display backlighting to compensate for

low-light and high-light environments.
You can enable or disable the ambient light sensor by pressing the <Fn> and

left-arrow key combination.

NOTE:

Do not cover the ambient light sensor with any adhesive labels. If covered

up, the ambient light sensor automatically sets the display brightness to the

minimum level.
