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
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 and the up-arrow key to increase brightness on the integrated
display only (not on an external monitor).
• Press 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 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.
