I just installed Windows 7 Enterprise for 90days from Microsoft website. I've installed this system in past and adjusting was worked correct. On this installation i can't adjust brightess, it's always on maximum, it's burning my eyes. Adjusting in Lenovo Power Manager not working. Why adjusting not working, my eyes cry and i have headache after few minutes because maximum brightness.

Re: B570e - can't adjust brightness.

Hi

 

Welcome To Lenovo Community

 

Please share the Display Drivers & Lenovo Power Manager details, like version and driver date etc.

 

Also Try the following , when the system is booting use the FN & Arrow key to decrease the brightness .

Confirm if this is working

 

 

 

Hope This Helps

Cheers!!!
