Deleted, after some more research, some of my information was premature and incorrect.

Just found out we've got a new thread! The other one was getting messy.

As mention in another topic, this issue has been confirmed by MS (Windows 7 SP1) in this document ( http://support.microsoft.com/kb/2498452 ).They suggest to look for updated Intel drivers from the vendor (Lenovo).

Re: R400/T400/T500/W500: Switchable graphics - NEW issues with 8.752.4 video drivers - crashes on In

I reinstalled my T500 with Windows 7 Professional with SP1 (downloaded from MSDN) - so I did not have to install the SP separately). I installed all Lenovo drivers using System Update. I did not install any beta software. Windows Live Mail 2011 and Windows Live Messenger 2011 crash after starting up - as expected.

 

Hopefully there will be an updated driver soon!

I would have replied sooner, but being ill for a few days, and needing to catch up at work has made me a bit behind.

 

Thank you JameZ, for all the time you have taken in this matter.  Your support, and that of a few core individuals that deal with us here are an asset to your company.  Know from us end-users, it does not go unappreciated.

windows update recommends update only up to 8.641 driver. even microsoft does not deem the latest 8.752 driver to be usable. this matter has gone far too long. from the simple matter of power issues, now we have crashes.... sigh

Hello, Same problem for me with a T400 with the latest Switchable Graphics driver (7vd616ww). SP1 does not appear in Windows Update, and running dxdiag gives me the following output:

 

Driver Name: igdumd64.dll,igd10umd64.dll,igdumdx32,igd10umd32

 

Driver File Version: 8.15.0010.2141 (English)

 

Driver Version: 8.752.4.0

 

Lenovo, please update your drivers - this is a very embarrassing situation for a business-class notebook.
