T400 Intel GM45 driver install issues

2010-12-16, 15:51 PM

My T400 has switchable graphics using the Intel GM45 drivers as one option.  I'm trying to update the integated grpahics driver to 8.15.10.2226.  Unfortunately though, I've never been able to update GM45 display drivers with any Lenovo driver because the install process has always stopped with the error, "This computer does not meet the minimum requirements for installing the software".

 

This morning, I decide to just uninstalled the Intel drivers and after a couple reboots now see the GM45 display drivers being reported as 8.15.10.2141.  This version doesn't appear in the list of Intel drivers provided by Lenovo but actually falls in-between two versions!

 

The other issue that has surfaced now is when switchable graphics are enabled in BIOS, the system crashes with a blue screen during startup.  It will run discrete graphics mode only or Integrated graphics only but not both.  My ATI HD3400 graphics driver is 8.752.4-101022a-107489C, dated 11-15-10.

 

Thanks for any suggestions or advice...
