Z480: Brightness issue after installing Intel Graphics HD driver from Intel

2013-02-04, 16:41 PM

I have IdeaPad Z480 with Windows 7 installed. I had installed all latest drivers from lenovo site.

 

Then I updated Intel Graphics HD driver to latest version: v15.28.12.64.2932 (9.17.10.2932) from Intel site and then I got problems: the brightness always revert to last brightness level (before updating Intel Graphics driver) when booting. Also, the brightness slider in Control Panel -> Power Options doesn't work anymore.

 

Reinstall Energy Management driver doesn't solve the problem. I suspect there is incompatibility issue in Lenovo Energy Management driver with the new Intel Graphics HD driver.

hi greybox,

please, un-install the drivers (the drivers you've downloaded from intel), restart your computer and install drivers provided by lenovo.

this should fix your issue.

hi yigit,

 

Yes, I know it will fix the problem.


The reason I upgraded the intel graphic driver because lenovo's intel graphic driver has gamma problem with "Warcraft 3" game. The driver made the game's gamma not functioning.

 

Using intel graphic driver from intel site doesn't cause gamma problem with the game, however I lost the energy management functionality.

 

So I got a dilemma here, it's between choosing the game or the energy management. If you guys can fix this problem, it would be great.

Hi yigit,

Z580's driver has same driver with Z480, look at the version number and released time, it's same. I had tried some of other lenovo product's driver too (I forget the series) and even win8 driver too, all of them doesn't work.

I think this problem can only be solved by lenovo's driver engineer. The Energy Management must be updated to fix the compatibility issue with latest intel graphic driver. Could you pass this information to them?
