How to Lighten the Screen on a Laptop
Depending on the kind of light you are working in, you may need to adjust the screen on a laptop to make it brighter. This is particularly true if you are in a dark setting or if sunlight is shining on the screen in a way that makes it difficult to see the on-screen text and graphics. You can lighten the screen on a laptop in just a few clicks.
Click the battery icon in the taskbar on the lower right corner of the laptop screen. A list will appear.
Select "More Power Options."
Click "Adjust the display brightness" on the left side of the window that opens.
Drag the bars next to "Adjust display brightness" to the right to add more light to the screen. You may drag either the bar under the "On battery" or "Plugged in" columns. You also may drag both.
Click "Save Changes." You now have lightened the screen on a laptop.
