Adaptive Brightness - Turn On or Off in Windows 8

How to Turn On or Off Adaptive Brightness in Windows 8 and 8.1


information   Information
This will show you how to turn adaptive brightness on or off to have Windows 8 use a light sensor (usually built into the display) to automatically adjust the screen brightness to match the lighting conditions in your PC's surroundings.

To determine if your laptop or computer monitor supports adaptive brightness, look for the Enable adaptive brightness setting in Power Options in the steps below. If the Enable adaptive brightness setting is not available, then it doesn't support adaptive brightness.

This will affect all users on the computer that use the same power plan that you have this set for.

1. Open the Advanced Power Settings for your power plan.​
2. Expand Display and Enable display brightness, then set adaptive brightness to be turned on or off for when your computer is On battery and Plugged in. (see screenshot below)​

I disabled every setting in Control Panel, disabled the Sensor service, disabled everything in the Intel Control Panel... still my display will lower the brightness every 10 seconds!
Now this laptop (Medion Akoya P2211T) is completely unusable in daylight. Always need one hand to constantly crank up the display to be able to read it comfortably.
I wonder if I should just try and load Win 7 on it...
