Laptop Screen Too Dim in Windows 10 and Windows 8

Since installing Windows 10 or Windows 8, have you noticed that your laptop screen is very dark? Even though you've set the brightness level, it may still be dark. A new feature in Windows 8, adaptive brightness, will control the brightness level of your screen. You can disable this in the power options advanced settings.

1. Go to Control Panel > Hardware and Sound > Power Options, then click on "Change plan settings" next to your active power plan.
2. Click on "Change advanced power settings."
3. Scroll down to Display, then under Enable adaptive brightness, switch it off for both the battery and plugged in modes.
