Hibernation and sleep instructions

1. Open the Power Options Control Panel. (Click Start, Control Panel, then double-click Power Options.)
2. Click on the Hibernate tab, check the "Enable hibernate support" box, and click Apply. (If this tab is unavailable, your computer can't do it.)
3. Click on the APM tab, choose "Enable Advanced Power Management support" and then click Apply. (On some computers Advanced Power Management is automatic, so this tab is unavailable.)
4. Click on the Power Schemes tab, then set how long before your system hibernates. (Vista's default setting is an hour. You can use this as your setting or change it to match your needs.)

To set your monitor to automatically sleep:

1. Right-click the desktop, then click Properties.
2. In the Display Properties dialog box, click the Screen Saver tab. Click the Power button next to the ENERGY STAR symbol.
3. Now you're looking at the Power Options Properties dialog box. You should be in the first tab, Power Schemes. Click the Turn off monitor list, and the time for monitor sleep to 5 minutes. If this is a laptop, set times for both 'Plugged in' and 'Running on batteries.'
4. Double click 'OK'.
5. To wake your monitor, just move your mouse, or press a key.What about Apple?
