T420s - Latest Optimus Drivers - IE9 Instability

[DangerMouse]

Hey there,

Has anyone who has an Optimus T420s started to suffer random crashes in IE9 when hardware rendering is brought into play ?

I have.

Here is the event log from one of the crashes :

Faulting application name: iexplore.exe, version: 9.0.8112.16421, time stamp: 0x4d76255d

Faulting module name: nvumdshim.dll, version: 8.17.12.7658, time stamp: 0x4f53bfb5

Exception code: 0xc0000005

Fault offset: 0x000034dd

Faulting process id: 0x1bc8

Faulting application start time: 0x01cd4053c1ccabf7

Faulting application path: C:\Program Files (x86)\Internet Explorer\iexplore.exe

Faulting module path: C:\Windows\system32\nvumdshim.dll

Report Id: 00ed2a91-ac47-11e1-8167-028037ec0200

As you can see : nvumdshim.dll is the offending file - never really had stability problems before now wondering if anyone else is getting them or if I'm the only one.

I had the same think on my rebuilt 520 with a fresh images. Both that and a green band across video playback such as YouTube wihich uses Flash.

They've not updated or optimized the drivers for these systems chipsets. It works fine in Chrome but crashed regulariy in IE 9, but 32 & 64 bit versions.

Do you think Lenovo will get some new Nvidia drivers out for the T420s that don't exhibit this problem ?

For the meantime I'm gonna try and hunt down the driver package before this one to stop this problem.

I'm currently using this one :

http://support.lenovo.com/en_GB/downloads/detail.page?DocID=DS014142

So 8.17.12.7658 - the previous version did not exhibit this problem.

Any ideas from anyone ?

See your PM

Cheers for that bro - Gonna try those now.

If anyone from Lenovo is reading - update your Optimus drivers for the T420s ! The ones you have up now are faulty.

Just use these ... http://www.nvidia.com/object/quadro-notebook-win7-winvista-64bit-296.70-whql-driver.html

I have always the retail Nviia drivers to be a) newer and b) faster and more stable.

I use 3.01 drivers.

[DangerMouse]

These are BETA drivers from NVidia for NVS4200 (3.01 Verde)

http://www.nvidia.com/object/notebook-win7-winvista-64bit-301.24-beta-driver.html

Those are Win 7 64bit
