Adjust Screen Brightness on Dell XPS
There are two ways to do this adjustment. For temporarily setting, you hold the Fn key and then press Up arrow key to take brightness up or press the Down arrow key to reduce the brightness. With this method, the brightness level will be restored to default on the next computer startup. So, for permanently setting, do following steps (instruction is for Windows 7):
- Select Control Panel in menu Start
- Choose Display
- Click on Adjust Brightness
- In the Plans shown on the battery meter, click on Change plan settings of Balanced option if this option is selected. Otherwise, choose Change plan setting of Power Saver.
- Adjust to suitable brightness levels for On battery mode and Plugged in mode using Adjust plan brightness sliders.
The second method can also be applied for other computers which is not DELL.
