I see we have a new BETA driver for the Quadro K5200 released March 11th.
Yes guys, heroic effort here. I'll be back at it soon.
And yes, the USB driver update needs to be installed from the normal desktop OS (not safe mode), or using C prompt, if necessary.
Looking at this a bit more:
What is Intel Collaborative Processor Performance Control? (from Intel)
A new technology based on the ACPI 5.0 specification that dynamically modulates performance vs. active application power. It reduces active power to deliver better battery life and allows deeper lower power states to be reached (compared to prior generations of Intel Core processor products).
Intel Driver Update Utility
IntelĀ® Driver Update Utility
Curious if @essenbe and @axe0 think this might help at all? Guess we should wait until we have the boot log though...
Ok, I'm in. I have the logon screen and I'll perform the tasks above and report back as soon as I'm done.
Running the Driver Update Utility wouldn't hurt, if we know what it wants to update. Assuming the Utility can read his chipset. It can't read mine.
