Waking up from sleep (Stand By) mode

To revive a snoozing laptop, simply press a key on the keyboard or tap on the mouse pad. That wakes the sucker up, bringing it back to active duty.

  • If you closed the lid to put the laptop into Stand By mode, then opening the lid usually wakes it up. See the section, “What happens when you just close the lid?” later in this chapter.

  • I generally push the Ctrl key on the keyboard to wake up my sleeping laptop.

  • The key you press to wake up the laptop is not passed along to whatever program is running. So if the screen says “Destroy all your data files? Y/N” and you press the Y key to wake up the laptop, nothing dastardly will happen.

  • Sometimes it’s necessary to press the power button to wake up a snoozing laptop.

  • If the laptop doesn’t perk up, then the battery is probably dead. Check the laptop’s power-on lights. If they’re off, then the battery is dead.

  • If the laptop still won’t wake up, then you may have a problem with the system’s power management software. Try pressing (and holding) the power button until the unit either turns off or on again. Then try starting up the laptop as you normally would. Refer to your dealer or laptop manufacturer for updated power management software.

“What the heck is hibernation?”

Hibernation is a great feature that’s often sadly ignored despite its great benefits. It’s like Stand By mode, but instead of merely entering a low-power state, the computer is actually turned off. Everything in memory is saved, however, so that when the computer is turned on again, it’s like you never left.

It just goes to sleep by itself!

Laptops are designed to go into Stand By mode when they’re under battery power. They do this after a set period of inactivity (no typing or mouse movements). Again, the design here is to save power; if the computer thinks you’re bored or off for a walk (or dead), it’s going to slip off to sleep to conserve power.

The delay time after which the laptop automatically enters Stand By mode is set in the Power Options Properties dialog box, obtained through the Control Panel. Refer to Chapter 8 for the details.

Here’s how to hibernate your laptop:

1. Save your work.

Do this as a precaution; you should always save your stuff. Even so, there is no need to quit any applications now.

2. Click the Start button.

3. Click the Turn Off Computer button.

The Turn Off Computer box thing appears. (Refer to Figure 4-6).

4. Press the Shift key.

You’ll notice that the caption beneath the Stand By button changes to read Hibernate. Keep that Shift key down!

If the caption does not change, then your laptop lacks the Hibernation feature (or it hasn’t been enabled).

5. Click the Hibernate button.

The laptop hums for a few moments, then it hibernates and turns itself off.

That humming is the laptop saving everything in memory to disk. When the laptop turns itself off, it’s really off. You can touch the keyboard or jiggle the mouse, and that won’t wake it up again.

To rouse the laptop from its hibernated state, turn it on. Refer to section, “Power on!” earlier in this chapter. (Though that section merely says to press the power button on your laptop.) You may have to log back into Windows, but eventually you’ll see the desktop and any open applications just as you left them before hibernating.

  • Waking up from sleep (Stand By) modeThe best way to tell the difference between a laptop in Hibernation mode or Stand By is that Stand By mode usually has that moon icon lit. In Hibernation mode, the laptop appears to be turned off. (Which it is.)

  • I prefer to put my laptop into hibernation if I know I’m not going to be using it for longer than an hour or so.

  • Waking up from sleep (Stand By) modeA big advantage of hibernation is that it’s quicker to start the computer than a regular start up. I know hibernation fans who always hibernate their computers and never really turn them off.

  • Unlike Stand By mode, you can leave your laptop in a hibernated state for as long as you wish. Even if the batteries eventually drain, the system will return to where you left it once the computer is plugged in and started again.

  • On some laptops, I believe that Hibernation and Stand By modes are both the same thing, though I cannot prove it.

Turning on Hibernation mode

If your laptop seems to be unable to enter Hibernation mode, follow these steps:

1. From the Start menu, choose the Control Panel.

2. Open the Power Options icon in the Control Panel.

Refer to Chapter 6 for more information if this Control Panel stuff has you perplexed.

3. In the Power Options Properties dialog box, look for and click on the Hibernation tab.

If there is no Hibernation tab, then there’s your answer: The laptop is not capable of hibernating. Oh well. (You might want to also check the laptop’s Setup program to see if hibernation can be activated there. Refer to the sidebar, “The laptop’s Setup program,” earlier in this chapter.)

4. Select the Enable Hibernation option by clicking the check box to place a check mark in it.

5. Review other options, if available.

6. Click OK to confirm the changes and close the Power Options Properties dialog box.

7. Optionally, close the Control Panel window as well.

Some laptops may require you to restart Windows for this change to take effect. If so, refer to the section, “I need to restart Windows,” earlier in this chapter.

Waking up from sleep (Stand By) modeNote that Hibernation mode requires hard drive space. When hard drive space runs low, it’s possible that Hibernation mode won’t work. Be aware of that.

Shutting down when the laptop doesn’t want to

Unlike a desktop computer, you just can’t yank that power cord from the wall on a laptop. The reason that doesn’t work is that with the AC power gone, the laptop immediately starts using its battery. This can be very disconcerting when the system is locked up and you really, badly want to turn the sucker off.

If the computer just utterly seems to be ignoring you, press and hold the power button. Keep on holding it down, usually for five to ten seconds. Eventually the laptop will turn itself off.

Refer to Part V of this book for laptop troubleshooting information.
