The laptop is connected to the wall plug, with the battery removed. I just leave the laptop on, go to sleep, and when I wake up, sometimes I'll find it already shut down (as opposed to the screen being turned off)
Sometimes 'whocrashed' will notice it, sometimes it will not.
A report from such a crash (not long after I had gone to sleep -- I must have left my computer sometime after 6 am):
On Fri 14-Aug-15 06:41:06 GMT your computer crashed crash dump file: C:\Windows\Minidump\081415-23571-01.dmp This was probably caused by the following module: nvlddmkm.sys (nvlddmkm+0x36E0B3) Bugcheck code: 0x1000007E (0xFFFFFFFFC0000005, 0xFFFFF88004C570B3, 0xFFFFF880033BDC98, 0xFFFFF880033BD4F0) Error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M file path: C:\Windows\system32\drivers\nvlddmkm.sys product: NVIDIA Windows Kernel Mode Driver, Version 355.60 company: NVIDIA Corporation description: NVIDIA Windows Kernel Mode Driver, Version 355.60 Bug check description: This indicates that a system thread generated an exception which the error handler did not catch. This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 355.60 , NVIDIA Corporation). Google query: NVIDIA Corporation SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M
Previously it was version
I do not think the issue is easily reproducible, so I doubt the service will even take it seriously. I feel they'll just unnecessarily reformat my system and hand it back to me.
