Unable to adjust brightness in my windows 8.1 (G50-70 laptop)

2015-06-20, 9:55 AM

I've noticed that I can not change the brightness of the screen. I can not change or buttons or brightness settings in the Power Options. I move the brightness bar and nothing happens.

Please help me. Thanks

Solved! See the solution

Hello,

 

It worked installing the first driver (Lenovo Energy Management Driver for 64-bit Windows)

 

Thank you very much.

 

Should I install the other drivers?

 

Thank you very much for your attention

 

regards

I have the same problem.

Unfortunatly installing the drivers didn't help at all. 

Is there anything else that can be done?
