The other option is where everything is saved on the HD and then Windows is shutting down. Is that Hibernating? Or how is it called?
From the article you gave me it sounds like Only one of the two is possible. How can I then select at Windows this or that one? Or is it then just deactivating the other one?
So, if I want to use your tool to get into Standby, I just need to deactivate Hibernation first, correct? Thank you, Greetings from South Africa!
