BSOD: Laptop didn't sleep, which driver to blame?
Ok, this started a month ago when I was travelling by car. I closed the lid of my laptop, slipped it into backpack and put it in car trunk for 5 hr. long trip. When I opened the trunk after 5 hours, I found the laptop bag at burning temperature. Apparently the laptop failed to sleep/hibernate and the fan kept running, and since it had no air to breathe in backpack, it just kept getting hot till it ran out of battery. Whew.. a bad experience for laptop and heartache for me. I rebooted the laptop after plugging in and all went fine then on, till today.
I have reformatted and reinstalled Win7 ultimate since the first incident. Same thing happened today. I closed the lid, but the fan kept running. I opened the lid, but the screen wont turn on. Reclosed the lid, and reopned, and I see the same old BSOD with a message:
STOP 0x0000009F DRIVER_POWER_STATE_FAILURE
I rebooted the laptop and its running fine. I understand this has something to do with some driver not letting the sleep/hibernate process run smoothly. But this doesn't happen often. So how do I find out which driver is the culprit?
