Re: Problem: video driver restarts; system: Latitude E6510, i7-720, FHD (1920x1080 display), 3100M, Win7Pro x64,
The system event log reports that nvlddmkm stopped, with an event id of 4101.
A series of web searches finally let me to a thread on notebookreview.com which seemed to indicate the problem might be related to the graphics chipset going into "powermizer" mode (although I see the problem when the system is using AC power -- powermizer supposedly is disabled then). At any rate, I've entered the registry settings which supposedly disable powermizer mode entirely. Now to see if that actually helps....
