W520 - screen brightness problems

2011-09-26, 12:04 PM

Hi :)

 

This is my first post here. I hope it goes to the right place.

 

I sometimes have a problem with my W520 FHD: I can not control the brightness until i reboot.

 

Can you tell me what the problem is?

 

Thanks.

Are you running the Lenovo factory image or did you re-install Windows 7?

Hi Ctrick:

 

Chances are that there is something wrong with the installation of the hotkey utility on your computer.

 

My suggestion is that you go to the W520 Device Driver File Matrix and download and re-install the package called "Hotkey Features Integration".  That is listed under the section "System Utilities".

 

My guess is that will get the problem fixed for you.  If it does not fix the problem, no harm will be done.

Hi, thanks for the replies.

 

I use the default Lenovo Image, no self-installed Win7.

The Error occurs sometimes after standby-mode.

 

I will try to reinstall the drivers, thanks :)
