Conserve Energy - Hibernate your Computer

Hibernate saves an image of your desktop with all open files and documents, and then it powers down your computer. When you turn on power, your files and documents are open on your desktop exactly as you left them.

Windows XP wakes from Hibernate faster than any earlier version of Windows. So you can preserve energy without taking time to close all your files and shut down, and then restart and open all your files when you're ready to work again. If you need to leave your computer, you can just leave it. Windows XP / 2000 can automatically put your computer into Hibernate mode after a specified period of inactivity. Or Windows XP / 2000 can detect when your batteries (if using hibernate on a laptop) are running low, and then automatically put your laptop in Hibernate mode to save your work before the battery fails. To put your computer into hibernation, you must have a computer that is set up by the manufacturer to support this option.

To automatically put your computer into hibernation

You must be logged on to your computer with an owner account in order to complete this procedure.

1. Open Power Options in Control Panel. (Click Start, click Control Panel, and then double-click Power Options.)
2. Click the Hibernate tab, select the Enable hibernate support check box, and then click Apply.
   • If the Hibernate tab is unavailable, your computer does not support this feature.

3. Click the APM tab, click Enable Advanced Power Management support, and then click Apply.The APM tab is unavailable on ACPI-compliant computers. ACPI automatically enables Advanced Power Management, which disables the APM tab.
4. Click the Power Schemes tab, and then select a time period in System hibernates. Your computer hibernates after it has been idle for the specified amount of time.

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.

1. You must be logged on to your computer with an owner account in order to complete this procedure. Open Power Options in Control Panel. (Click Start, click Control Panel, and then double-click Power Options.)
2. Click the Hibernate tab, and then select the Enable hibernate support check box.
3. If the Hibernate tab is not available, your computer does not support this feature.
4. Click OK to close the Power Options dialog box.
5. Click Start, and then click Shut Down. In the What do you want the computer to do drop-down list, click Hibernate.

If you are using Windows XP Home Edition, or Windows XP Professional with Fast User Switching turned on, the Shut Down menu will present the options to Stand By, Turn Off, or Restart your computer. Hold down the Shift key, and the Stand By button will change to Hibernate.

Hibernate with Windows Me?

Windows Me does support Hibernate, which allows you to save the contents of RAM to the hard drive and then recover it all when the system comes out of hibernation: This allows you to leave programs running and then have them return to normal when the system comes back up. But Hibernation in Windows Me is very restrictive and it won't work on all systems. First, you need an ACPI-compliant BIOS, as you do in Windows 2000. But then the complications set it: If any of the drivers on your system are not hibernation compatible, the feature will not work, or even appear in the UI. At this point in time, most installs of Windows Me do not include hibernation.

PC makers will include the necessary drivers for hibernation in their Windows Me systems.

If you had hibernation working and it suddenly disappeared, it's probably because of a new driver installation: Many hardware drivers aren't compatible with hibernation. Check nohiber.txt in c:\windows for details.
