R400/T400/T500/W500: Switchable graphics issues with Win 7 - FIXED AT LAST? [ Edited ]

Run the driver setup so it extracts it's contents to C:\DRIVERS\...

1. Open Device Manager, right-click the Intel graphics card, Update Driver Software.
2. Choose "Browse my computer ...".
3. Choose "Let me pick ...".
4. Click "Have Disk".
5. Point it to:
32-bit: "C:\DRIVERS\WIN\VIDEO\Packages\Drivers\Display\W7_INF"
64-bit: "C:\DRIVERS\WIN\VIDEO\Packages\Drivers\Display\W76A_INF"
6. Select the sole entry in the list and hit Next.

7. Continue from there.

Might work, might not.

Tried it, programs still crash. Thanks for the suggestion.

I experience problem on Firefox 4 Beta 7, IE 9, and Live Messenger 2012 when Intel driver is being used on Win 7 64bit. No problem on ATI. Fortunately, my outlook 2010, chrome 9 and firefox 3.6 works fine. Wait and see whether anyone experience the same problem and whether there is workaround.

I experience the same problems as you do on the same programs, seems something is wrong with the Intel driver on Windows 7 64-bit. It seems as if people with the 32-bit version have no problems at all.

The CLI Error that occurs when CCC is started with the new driver occurs even when you do a fresh Windows 7 64bit install. So it is clearly a driver issue not an upgrade issue. Im back to the 2009 driver for now...

[ColonelONeill]

Yeah it looks like a 64-bit only issue; I'm running the new version fine on 32-bit.

[Edbert]

Hope Lenovo notices the issue and does something about it!

This driver works well on my T400 Win7 x64.  I pulled the old 10.8's out that I force installed earlier in the month.  I didn't encounter any issues during the installation and I can run 3D applications using the Intel chipset just fine.  I did however get a decrease in my Windows experience index.  My graphical index decreased from 4.8 to 4.7.
