Sorry folks, I have tried googling this but I failed.
Computer crashes right at the end of hibernation (or at least, somewhere during it). So it saves the memory to disk, but then it seems to die, and when I come to restart it I get the ‘windows didn’t shut down successfully’ thing. Windows isn’t actually running at this point so no crash dump logs.
Any clues as to where to start looking? I was wondering if it was related to the fact that the bluetooth device randomly starts and stops sometimes. I thought perhaps it wasn’t able to enter the right power state – but wouldn’t that happen before saving memory to disk rather than after? I think that’s a dodgy connection anyway since there are no driver crashes in the logs for that.
