Re: IdeaPad P500 screen went dim

Here is a cut and paste from another topic I found through laborious searching.  My P500 is basically a Best Buy packaging of a Z500, so I figured I'd give this a shot, and it worked!  Hope this helps others.

 

Finaly finaly after 5 hours searching, I found the best solution:

 

1- install latest driver of Intel Hd Graphic 4000

2- install latest driver of your graphic card

3- This step will fix the problem:

- go to registery by regedit and change the value to 0xf048

 

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
"FeatureTestControl"=dword:0000f048


 OR


[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001]
"FeatureTestControl"=dword:0000f048

 

this will fix the problem.
