Update: If you skipped Windows 8 and upgraded directly to Windows 10, you saved yourself a lot of problems, so good on ya! The same power options exist on it as well. Make sure to check out our article on how to enable Hibernate on Windows 10 and our guide on how to shutdown, restart, hibernate, or sleep Windows 10.
I have known about this methord of turning on Hibernation for some time, but I have not been able to find a way to keep the machine turned on for more than 5 seconds ofter trying to hibernate. If you can come up with a way to do that I would be a happy man..
My God, maybe Microsoft should contract you out for their technical support. They could not even tell me how to enable hibernation in windows 7 64. They led me throught the cmd entry, but your site took me further to correct the issue. Thank you sooo much!
Windows 7 provides power saving features in the shutdown options. If you do not want to shut down your computer (you just want to step off your computer temporarily), windows gives you the sleep and hibernation feature to save power while you are away. You can go to the hibernation or sleep mode directly from your start menu, under the power options.
There is a hidden system file named Hiberfil.sys located in the root folder of the drive where the operating system is installed. The Windows Kernel Power Manager reserves this file when you install Windows. The size of this file is approximately equal to how much random access memory (RAM) is installed on the computer. So if you have a 4GB RAM the Hiberfil.sys file will be between 2 and 4GB depending on the data stored in it. The computer uses the Hiberfil.sys file to store a copy of the system memory on the hard disk when the hybrid sleep setting is turned on such that everything that is loaded to the RAM will not be lost. If the Hiberfil.sys file is not present, the computer cannot hibernate.
It is obvious that hibernation uses a substantial amount of your hard disk space, and if you are someone that is bent on saving time, hibernating can cost you a little. So how do you disable hibernation such that your computer will never hibernate? This article describes how to disable and then re-enable hibernation on a computer that is running Windows.
