Hibernation (re-visited)

    Question

  • I have been doing further tests with Hibernation. I am testing in a VM using VMWare Workstation 7.1 using Independent persistent disks (changes are immediately and permanently written to the disk).

    I can turn hibernation on via the commandline using 'powercfg -H on '. having done this I can see that there is a hiberfil.sys file on the C Drive. So far so good :-)

    I then issue a 'shutdown -h ' command and Vail then hibernates. I restart the VM and get the message 'Resuming Windows ...'. On completion of the restart, I can log on and the hiberfil.sys file is still present (I would expect it to be).

    I now do a normal shutdown (from the start menu) and the VM successfully ends. I then restart the VM and log on.

    However, the hiberfil.sys file has now disappeared and if I try a 'Shutdown -h ' from the commandline, I get the message: "Hibernation is not enabled on this system. You must enable hibernation in order to use the -h option. " :-|

    So my question is - shouldn't Vail "remember" the powercfg setting across a re-boot or is there another option I have to set. Just wondering if anyone else has tried this and got it to work OK?

  • Are you sure you're using the correct options and syntax for powercfg? See this KB article.

    Pretty sure ;-)

    This below is from typing in 'powercfg /?' from a commandline prompt in Vail:

    -HIBERNATE, -H
                Enables-Disables the hibernate feature.  Hibernate timeout is not
                supported on all systems.

                Usage: POWERCFG -H <ON|OFF>
                       POWERCFG -H -Size <PercentSize>
                -Size  Specifies the desired hiberfile size in percentage of the
                       total memory. The default size cannot be smaller than 50.
                       This switch will also enable the hiberfile automatically.

  • Not that I know off / did not try...

    I supose you did test with a "clean" server install?
    In other words: no other 3th-party programs, tooling, browser addons that could "fix" the power config?

    Did yoy check the event list for any power related warnings/errors?
