T420s Crashes with Discrete and Optimus Bios Display Setting

2012-10-26, 21:32 PM

I am running windows 7 64bit and when I boot my laptop crashes and reboots over and over when I have the BIOS Display setting set to Discrete or Optimus. If I use the integrated graphics setting it boots up just fine, but I am not able to use my dock w/ external monitor properly.

 

The event viewer renders no useful information about the issue. I have installed the latest Intel display driver for my HD 3000 videocard. Has anyone has a similar issue?

Hi codeblue2k

Uninstall the current NVIDIA driver in Integrated mode, switch back to Optimus in BIOS, and install NVIDIA driver again through ThinkVantage System Update.

Have a nice day! :smileytongue::smileyhappy::smileyvery-happy:
