I see that this was already discussed in the past; but for me hibernation on Windows 8.1 still does not always work properly.

Link to previous question: http://social.technet.microsoft.com/Forums/windows/en-US/238ec268-a2dc-49ab-8a75-c185710e086a/windows-81-sleephibernate-issues?forum=w8itprohardware

I have Windows 8.1 64 bit Pro installed; I also have all updates installed. I can always hibernate my PC, but the problem is that on startup it sometimes wakes up properly with all launched applications "still running" (of course I understand that they were not running while the power was off); but sometimes it fails to start up and go back to previous state and performs a clean boot instead. When it fails it seems completely random. I see no error messages. It is like after hibernation there is a 30% probability that Windows will forget that it was hibernated and perform a clean boot instead.

I remember that Windows 7 as well as Windows 8 systems didn't have this issue; hibernation worked properly always.... I like Windows 8.1, but this issue with hibernation is... well.... spoils the impression a bit.

I have a desktop PC with a "usual" hard drive and a SSD drive; Windows is installed on SSD drive. No UEFI support.

   Plz help. Anyone knows how to solve this? I would really appreciate it.

P.S: I am not talking about sleep mode; I only discussing hibernation here. I hibernate PC because it is good for my workflow. I often have many applications opened and I like when they stay opened because starting them again and opening projects and documents takes time.

Hi,

This issue can be caused if the Hiberfil.sys was corrupted or it was larger than the capacity of C drive, then System cannot boot properly from Hibernation.

Hiberfil.sys file is a system file that is used by Windows to support Hibernation. If you have enabled Hibernation in Windows 8.1, you will see this file.

I suggest we try to re-built this file to check the results:

powercfg.exe /hibernate off

powercfg.exe /hibernate on

Then, if possible, please make sure that there is enough space in your C drive for Hibernation.

Meanwhile, please upload the event log here for further research.

Collect event log:

Please upload them to a file sharing service like Skydrive or "Rapidshare" and put a link to them in your reply.

Look forward to your response.

Thanks for your hints;

I uploaded my event log to my SkyDrive account; here is the link: http://sdrv.ms/1b8mCBp. I believe I made the file available; sorry if I got this wrong. I exported all log events from Windows Logs\System group.

While looking at the list of events I noticed that there are some events with "Critical" level; source: "Kernel-Power". Description panel says: "The system had to reboot due to errors". Since I definitely did not experience sudden system reboots while working, I believe that these error messages indicate exactly those cases when system could not restore from hibernating. I also noticed that this particular error occurred on the following days: January, 17th: two times, 16th: once, 15th: once, 17th: once, 13th: twice, then on 6th once and 5th once. I almost sure that these are the moments when I my PC failed to restore from hibernated state. Looks like these are log events representing start-up failures after hibernation: Critical, src: Kernel-Power.

I checked free disk space; I still have 86 Gigabytes available on my C: drive; I have even more free disk space on my second drive.

I executed the commands you suggested. I will see if it worked in a while. Can't tell for sure right now because I haven't tried hibernating my PC yet; and I will have to test it for several days to be sure because, like I said, sometimes it works, sometimes it does not; well, you got it.
