Welcome aboard.

Apparently it is crashed by WDDM KMD Loader - DisplayLink Core Software.

Probably caused by : dlkmd.sys ( dlkmd+19d12 )

Followup: MachineOwner
Try to update it from DisplayLink: Windows Software.

But, the main reason behind it is the display driver.

Update it, either from AMD Graphics Drivers & Software or from the manufacturer's website.

Let us know the results.

Lenovo doesn’t support this notebook with W7 drivers. The ATI Mobility FireGL V5250 driver from Dec 2008 actually is latest driver picked up by W7 Update. I rolled back the driver to this Windows Vista driver by installing over the one from 2008:

Video driver (ATI Mobility Radeon, FireGL PCI Express-2) for Windows Vista (32-bit, 64-bit) - ThinkPad R60, T60, T60p, Z61m, Z61p

I’ll keep you posted if notebook stops crashing.
