Fellow Users (and Lenovo Specialists) -
Since delivery at the end of August, I have been unable to remedy problems with the Display Driver. It routinely throws 4 back-to-back error messages before the laptop will finish loading into Windows 7 Professional (64 bit). I have run all of the Windows Updates as well as all of the Lenovo Thinkvantage System Updates.
The Application Name is igfxext.exe and the Problem Event Name is BEX64.
The version of the driver currently in use is 22.214.171.12478.
The Display Type is HD (1366x768)
The Machine Type is 2359.
Does anybody know a solution to this problem outside of requesting Warranty repair?

It is an Intel GPU only.
I agree the version on the Website appears to be different (126.96.36.19988 - released 09/06/2012 per the README file); however the self-extracting executable (g1d624ww.exe) contains files from Intel which install version 188.8.131.5278 dated 06/06/2012. I made this comment using one of those "Was this page helpful to you?" boxes on the Website several weeks ago in hopes that a more recent version would be uploaded to the Website, but nothing has been updated. If you can find me a more updated driver, I would love to load it in hopes of resolving this problem.

I did not have a case number. It was one of those anonymous feedback boxes asking if the solution was helpful (yes/no) along with a text box to leave comments.
Within the past few days, I accepted an Update via Windows Update for the Lenovo USB to DVI adaptor that changed the behavior of the error. This change has led me to discover the problem seems to be the interaction of the Video Driver and the USB to DVI video driver. The problem had been that the crash would occur on the laptop only when it was undocked from the Mini Dock Series 3. After the update, the crash would only occur when it was docked and connected to the USB to DVI adapter.
The updates seem to be through DisplayLink, so I did some testing. I removed the DisplayLink software, reinstalled it from the Lenovo Website, and applied the updates from the DisplayLink website. At each version, the crash would only occur when it was docked and connected to the USB to DVI adapter.
I removed the DisplayLink software and reinstalled it from the Lenovo Website a second time. Again, the crash would only occur when it was docked and connected to the USB to DVI adapter. This time, I updated through the "Check for updates..." option from the Lenovo USB to DVI Adapter in the System Tray. After the update, the crash only occurs when the laptop is undocked.
It would appear that following the update path through the Lenovo USB to DVI Adapter in the System Tray successfully eliminates the crash when the laptop is docked in favor of causing the crash when the laptop is undocked. Of course, I would prefer it not to crash in either configuration.
Where do you think we go from here?

Actually, it was only occuring lately when undocked. It had moved from a docked to an undocked problem. It seemed especially odd, since the Lenovo USB to DVI adaptor is not connected when undocked.
I had updated the BIOS along with any other update indicated by ThinkVantage System Updates previously. I used the Website approach you mentioned and found several more updates to apply. There were quite a few updates available on the Website.
I'm happy to report that after applying all of the available updates that the problem has been resolved. I no longer have issues either docked or undocked. I can only assume one of the newer updates not yet available through the ThinkVantage Syatem Updates Website resolved the issue.
Thanks for your help.
