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?
