That file is part of the Intel graphics driver.  If you aren't using the most recent one which Lenovo released I would try installing it.  You may also have to experiment with different releases to find one which works well.  These drivers seem to be a little bit of a mixed bag with no one working perfectly on every system.  The driver is also more likely to fail when the system has unmatched memory installed (like mine with 3gb).  My option was actually just to set the system to run on the ATI drivers all the time and use the latest drivers from ATI.

I have ThinkPad W520 w/ NVIDIA Quadro 2000M Optimus, and Intel HD Graphics Family. Last week, I went to "www.lenovo.com" website and download the latest drivers under "support --> ThinkPad Products --> New Released Drivers". I downloaded:

ThinkPad Power Mangement Driver (8jku02ww) ver. 1.64
Power Manager (8mu414ww) ver. 3.64

for my Win7-64 Pro. Before installing, I created "system restore point", and I first installed the ThinkPad Power Management Driver, reboot the W520, everything seems working fine.

I then create another system restore point, and I installed the "POWER MANAGER", reboot the W520 and I got error "igfxext module stop responding....".

I went back to the system restore and restore my W520 back before installing the "POWER MANGER", and the W520 works fine......

Lenovo has a lot of problems with the drivers....!!!!!! However, Lenovo is good laptop. Hope the info. help!

Hi there,


I am getting this same exact error.  What could be causing it?  I have all the latest drivers from "Software Update".  Also, you mentioned that you "actually just to set the system to run on the ATI drivers all the time and use the latest drivers from ATI."


How do you run on only the ATI drivers?  I must admit, I cannot for the life of me figure out WHY there are both ATI and Intel drivers here.  I thought the ATI drivers would be the only one used, but sure enough, when I uninstalled the Intel drivers, the video failed completely...  I don't understand at all...

I have a W520.  I had the same errors whenever I reboot or change status like unplugging and plugging back in.  It was the DisplayLink drivers that had been updated.  I use a ThinkVision LT1421 Travel Monitor and I had to revert to version 6.2 from April.  All is working well now.  Lenovo uses the same technology for the port replicators as well.  Hope this helps somebody.

I get the same popup message whenevermy T410s decides to show it.

It shows especially when I start to playback the video.

It is very ennoying indeed.
