To manually put your computer into hibernation
You must be logged on as an administrator or a member of either the Administrators or Power Users group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.

Open Power Options in Control Panel.
Click the Hibernate tab, and then select the Enable hibernate support check box.
If the Hibernate tab is not available, your computer does not support this feature.

Click OK to close the Power Options dialog box.
Click Start, and then click Turn Off Computer. In the Turn Off Computer dialog box, click Hibernate.
Notes

To open Power Options, click Start, click Control Panel, click Performance and Maintenance, and then click Power Options.
When you put your computer into hibernation, everything in computer memory is saved on your hard disk. When you turn the computer back on, all programs and documents that were open when you turned the computer off are restored on the desktop.

To put your computer into hibernation, you must have a computer whose components and BIOS support this option.
Using Power Options in Control Panel, you can adjust any power management option that your computer's unique hardware configuration supports. Because these options may vary widely from computer to computer, the options described may differ from what you see. Power Options automatically detects what is available on your computer and shows you only the options that you can control.
