I have a strange problem with my Lenovo T520. Since last week, every wake from hibernate has failed right after the Windows 8 logo shows up. The computer simply dies (like I removed the battery, or as if it overheats). When I turn it on again it boots fine, with seemingly no problems or errors. During normal operation I have noticed no issues.

I have had some problems with my discrete GPU, and thought this might be an issue but I've disabled the GPU in bios and it hasn't helped.

To be honest, I don't even know where to begin in terms of troubleshooting: the Windows logs don't register anything abnormal.

Any ideas?

After some more googling I found solution on the answers.microsoft.com website:

  1. Run cmd.exe as an administrator.
  2. Execute command: bcdedit -enum all. Look for Resume from Hibernate in the output and note the identifier part (i.e. {3d8d3081-33ac-11dc-9a41-806e6f6e6963}) or copy it to clipboard.
  3. Execute command: bcdedit /deletevalue {identifier} inherit (bcdedit /deletevalue {3d8d3081-33ac-11dc-9a41-806e6f6e6963} inherit in this example).
  4. Test hibernation again.

I tried it and it now works. However, I don't know why. My guess is that the hibernation file was corrupted for some reason. Is this the case? Should I be concerned that my hard drive is dying?
