I put my system to sleep every day but lately, when I resume/open my laptop lid. It starts the windows again and it is a boot all over again.Upon search logs on @Dave way, I found out a critical Kernal-Power which says

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

I did google but the scenario provided here don't fit me, as I had put my system to sleep.

I looked in yesterday event, when I put my system to sleep and error says

The previous system shutdown at xx:xx:xx on ‎22/‎06/‎2017 was unexpected.

This is the time, I put my system to sleep.

How can I find which app/service is crashing so I can rectify the problem

Edit: It is worth noting here when it starts the next time, it is really sluggish for good 15-30 minute e.g. I cannot do anything until then.

    We don't either as we can't look at your log. Interesting is errors and startup/restart/shutdown events and anything happening around the restart time. – DavidPostill Jun 23 '17 at 8:32
  • @DavidPostill If you tell me any kind of event/name I should look for then I will be able to tell you – Nofel Jun 23 '17 at 8:33
  • you can always screenshot your recent event logs and post it here – Vylix Jun 23 '17 at 9:12

    If you put your pc to sleep, wait 10 minutes, then fire it up, does it happen then also? And if you wait 1 minute? does it happen then? It is possible your laptop is running out of battery and sleep still requires battery. Consider hibernating instead. – LPChip Jun 23 '17 at 10:22

I had this problem with my ASUS ROG GL552VW laptop and it was fixed by re-flashing the BIOS.

To do this, download the latest bios from the manufacturer's website (in my case, ASUS) and a BIOS flashing utility (WinFlash for me)

Run the flashing utility with the BIOS you downloaded.

I also had to run the utility with the /nodate command line as the BIOS version was the same (and so the utility would not allow a reflash). To do this, run > cmd > cd C:\Program Files (x86)\ASUS\WinFlash (or similar) > Winflash /nodate and the utility starts as normal.
