The other day when I woke my laptop from sleep, the front indicator light turned on, I could hear the processor fan, but the screen was black (there is no dedicated on/off button for the screen). One hard shutdown later, I get the obligatory "Windows shut down unexpectedly" window after logging in, with the details saying it was a BSOD.
The last time this happened was a few months ago when I had old chipset drivers. I've had the updated ones for about 3 months with no issues.
Any idea why this would happen?
Here is my BlueScreenView log:

It hasn't happened since, and I'm hoping it doesn't ever.
