Windows 7 guest crashes when hibernating

[VBoxer11]

Hi,

I'm using Snow Leopard and my VM is a Windows 7 Home Premium guest. Every time the Mac OS X host hibernates (due to energy saving settings, see below), the Windows VM powers off the hard way (I mean without properly shutting down). The next time I start the windows VM, it starts with the black failure screen "Windows wasn't properly shut down". I never had this problem with Linux hosts, so the reason seems to be the Mac host. I still want to use energy saving and quickly pause the VM by saving the current state. How can I avoid powering off the VM?

My energy saving settings are:
- hibernate computer after 15 minutes
- hibernate monitor after 10 minutes
- if possible, activate hibernation for hard drives
- wake up on network access
- enable activating hibernation on on/off-switch
(the translation might not be accurately, because I'm not using the English language settings).

Thanks in advance!

Hi again,

finally I found a solution for my problem and I want to share it with you for those who have the same issue.
As stated, the problem was concerned with the energy saving settings. After I changed the power plan and set "Put the computer to sleep: Never", everything works fine now.
Hope this will help you.
