I've tried everything I can think off to turn off hibernation.

I have disabled it in power management, used powercfg -h off and it almost works. It works when I execute the command but when I reboot the file hiberfil.sys is created again.

How do I do to turn off hibernation and delete the hiberfil.sys file for ever?

You could also try to turn off Hybrid Sleep :

  1. At the command prompt run as administrator, type powercfg.exe /hibernate off
  2. Start menu > type Power options
  3. In the left pane, open the link labeled Change when the computer sleeps and then open the link Change advanced power settings.
  4. Under the Advanced Sleep options, expand the Sleep tree and turn off Hybrid Sleep.
  5. Press OK.
  6. Reboot.

Alreadu tried that, didn't work. –  Tomas Jansson Nov 15 '11 at 11:14
I suggest then to (1) Look in all the Sleep branch and turn off everything possible, (2) Try to boot in Safe mode so if this doesn't happen then it is caused by a startup application. –  harrymc Nov 15 '11 at 12:27
that's a good tip to verify that it is a startup application... but it won't solve the problem. –  Tomas Jansson Nov 15 '11 at 12:52
If it is really a startup application, then one can use Autoruns to turn them off selectively until finding the guilty one. –  harrymc Nov 15 '11 at 13:01

I don't know if it matters but I always turn it off with the following command:

powercfg -h off

as opposed to:

powercfg /h off

Sorry, this was not the issue. It was just a typo. My problem is that I manage to turn it off, but when I reboot it gets activated again. –  Tomas Jansson Nov 14 '11 at 19:53

Something is turning it back on.

Try running Autoruns to see what is running automatically when you boot.
Is there a program or a scheduled task that does this?

If you don't see anything, run Process Monitor and enable boot logging (remove the filters to avoid filtering out the calls), then look for "hiber" and see/post what you find.

I don't want to try boot logging again, the last time I did so the computer get into a "permanent" blue screen. I couldn't even boot into safe mode after I activated boot logging with process monitor, but I will check up Autoruns. –  Tomas Jansson Nov 14 '11 at 20:00
@TomasJansson: Oh that sucks... do you remember what the error code was? (Either the number or the STATUS_SOMETHING_HAPPENED message would be useful.) –  Mehrdad Nov 14 '11 at 20:06
error code of the bsod? –  Tomas Jansson Nov 14 '11 at 20:07
@TomasJansson: Yeah –  Mehrdad Nov 14 '11 at 20:08
I guess you mean "BAD_POOL_CALLER". I'm not 100 % sure that Process Monitor caused it, but I don't want to try it just right now since I don't have the time to set the computer up again if it fails. –  Tomas Jansson Nov 14 '11 at 20:09

Just delete the hiberfil.sys file from C:. As an added advantage you will save a few GB's of disk space too!

I don't think you can delete it if hibernation is activated, and the command powercfg -h off will turn off hibernation and delete the file. The problem is that when I reboot hibernation is re-enabled for some reason. –  Tomas Jansson Nov 15 '11 at 11:15
well, I have a dual boot PC with Win7 and Ubuntu, and deleted hiberfil.sys with ubuntu. from that onwards i don;t have hibernate option on Win7. –  Vineet Menon Nov 15 '11 at 11:20
I can't, for some reason it says that the file is in use and I can't delete it that way. How ever, it works to delete it using the powercfg -h off, but it doesn't solve my problem. –  Tomas Jansson Nov 15 '11 at 11:40
since you have already tried a lot of things, try to delete that file using some other OS (a linux live cd, if you wish). I don't know it will work or not, but give it a try. –  Vineet Menon Nov 15 '11 at 11:44
I will try that when I get home. It is a MacBook with dual boot, so I can just try to delete it from my OSX partition. –  Tomas Jansson Nov 15 '11 at 11:58

The Hiberfil.sys hidden system file is located in the root folder of the drive where the operating system is installed. The Windows Kernel Power Manager reserves this file when you install Windows. The size of this file is approximately equal to how much random access memory (RAM) is installed on the computer.

The computer uses the Hiberfil.sys file to store a copy of the system memory on the hard disk when the hybrid sleep setting is turned on. If this file is not present, the computer cannot hibernate.

Follow complete details on this link as Microsoft support

Use following command to turn of hibernation

 powercfg.exe /hibernate off 

and off hybrid sleep setting from Advanced Power Settings.. See the @harrymc answer to where to do this..

If you are having some issues with windows then use Microsoft Fixit. it is nice utility. I was using this with my Genuine Windows XP operating system.

I asked the question at and got the answer here: Microsoft Answers. So here is how you really find what is turning your hibernation back on again using clean boot.

1. Start msconfig.exe
2. On the general tab select "Selective startup" and uncheck "Load startup items".
3. On the services tab unselect all first. 
4. Runt the command "powercfg -h off" to turn off hibernation.
5. Reboot
6. If hibernation is still deactivated start msconfig.exe again and activate half of the services.
7. Repeat 5 and 6 until you find the service causing hibernation to be turned back on (don't forget to do step 4 if it is activated again).

Autoruns is much easier to use than msconfig. –  harrymc Dec 27 '12 at 20:25
