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).
Switching the Video Image
When you start the computer with an external device (such as an external monitor or projector)
attached and turned on, the image may appear on either the computer display or the external device.
