Hibernate is different from sleep. To enable hibernate, go to control pannel/power options/hibernate, and enable it. Now, go to start, turn off computer. You should see the stand by option, turn off option, and restart option. Press shift. The stand by option should be changed to hibernate. Now hibernate the computer.
When windows hibernates, it saves everything to the hard drives, and then shuts down. You can unplug the power, and the computer will still memorize everything. When you turn the power on, windows will directly go to your last setting, which was saved on your hard drive.
