is a power management feature. When you hibernate a laptop, you're essentially
turning it off. So, unlike Stand By (Sleep) mode, a hibernated laptop
isn't using any battery power at all - that laptop is off!
secret behind hibernation is that before you turn off the laptop,
everything you're doing with the computer is saved. (The contents of
memory are saved to the hard disk.) When the computer is turned on
again, it recovers from hibernating by reloading all the saved
information and restoring your laptop to exactly the same condition it
was in before it was hibernated.
Briefly, hibernation works like this:
1. You activate the hibernation feature.
Hibernation is activated differently depending on how it's set up.
2. The laptop hums as everything in memory is saved to disk.
3. The laptop turns itself off.
really and truly off: The battery isn't being used, and it's safe to
store the laptop or put it away until you need to use it again.
recover from Hibernation mode, just turn the laptop on. In some cases,
the laptop may recover from hibernation when you press a key or touch
the mouse pad. hibernated state for as long as you want.
mode requires hard drive space. So you should be aware that when hard
drive space runs low, it's possible that Hibernation mode won't work.
In Windows XP, you have to activate Hibernation mode before you can use it. Follow these steps to activate Hibernation:
1. Click the Start button.
2. From the Start menu, choose Control Panel.
3. Open the Power Options icon in the Control Panel.
4. In the Power Options Properties dialog box, look for and click on the Hibernation tab.
If you don't see a Hibernation tab, there's your answer: The laptop isn't capable of hibernating. Oh, well.
You might want to check the laptop's Setup program to see whether you can activate Hibernation there.
5. Select the Enable Hibernation option by clicking the check box to place a check mark in the box.
6. Review other options, if they're available.
7. Click OK to confirm the changes and close the Power Options Properties dialog box.
Optionally, close the Control Panel window, as well.
Some laptops may require you to restart Windows for this change to take effect.
