First, the computer right click on the desktop, in the Open menu click "Display Settings" and then open access, the effect is as follows;
Then we open the interface, we click on "Automatically adjust the screen brightness", open it, as shown in the following figure.
Two, another way to set in the Power options,
We can go to the control panel---"Hard disk and sound"---"Battery options" in "Start" and then click "Change plan Settings" as shown in the following figure;
When entering into the edit schedule setting, we click "Change Advanced Power settings" and then we click on it to open the entry;
Then, in the Power Options interface, we find "show"---"Enable adaptive brightness"-"enable".
Note: If you find that there is no effect after the adjustment, this reason is because your hardware is not supported, because the brightness is also the need for hardware support oh, good hardware will definitely effect better.
