Dell 1520 Vista sleep state bluescreen

When I close my lid for my laptop and stick it in my bookbag, shortly there after I sometimes here the vista startup sound. I then find that windows restarted and has recovered from an unexpected shutdown. In my event log I see that it is a bluescreen, bugcheck

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000009f (0x00000003, 0x83e5c5a8, 0x85f8a030, 0x8459ee28). A dump was saved in: C:\Windows\MEMORY.DMP.

I formated the laptop as soon as I got it and am using Nvidia 163.14 drivers. Anyone know how to prevent this. I've installed all the microsoft hotfixes that pertain to 0x0000009f, at least I think I have. Any help is greatly appreciated.

 

I have also been experiencing this problem but on my Sager 2090, although it does not happen every time. When I check the event logs, it says my notebook has failed to transition into the sleep state so the notebook had to restart itself.

 

Hm, mine doesn't do it all the time either, must be a common Vista bug or a driver bug.

 

Check out these fixes from microsoft. I have a similar problem, although it's not quite the same. My laptop crashes upon waking up and also occasionally during startup. I'm not sure what I have is what these fixes are for, but I'm giving them a try anyway.
