You can use Hibernate on W/7 if you so wished.
It took me about 3 months to find a way to install SP1 on my W/7 computer.All I can remember was I had to install it from a different source but cannot remember what.
You should get free advice from Microsoft as it is one of their updates.
Hibernate.Go to control panel.Power Options.Click on choose what the power button does.Then click on the dropdown box and choose Hibernate.
Not sure if you had problems with your computer whether that setting could interfere with any recovery work or not.XP used to give you the oppertunity of choosing which way you wanted to shut down and I am not sure if W/7 will be the same or not as I have not tried it.
