Z580 Problem with led brightness on windows 8?

I changed my laptop power plan's options to make the led brightness 100% when plugged-in ..........

When I restart ...... It appeared that it is now 100% but it is actually not 100% ......... When I try to increase the brightness by keyboard the meter appears and tells that it is 100% ..... But actually I can increase more to reach until 100% without any changes with meter ...........
So every time I restart I have to increase the brightness from keyboard because windows 8 adjust it as 100% but actually it is not !!!!!!!! ( calibrating problem I think) ..   Windows 8

Hi Again!!
Please install the windows 7 version of lenovo energy management and then also update the Intel HD Graphics Driver from the lenovo site itself.
Hope this solves your problem!

He needs to use the Lenovo Intel graphic driver, if he uses the one from the intel website he will have problems with the brightness control as lenovo have modded the intel graphic driver.

Where can I find the update for the Intel HD 4000 Graphics on the lenovo site?  I can't find it in the driver matrix?

I wish somebody could figuer out how to mod the drivers from the itel website so the brighness still works, in a few years these lenovo drivers are going to be really old.
