How to Change Your Laptop’s Power Button Functions in Windows XP
In Windows XP, you can control what your laptop does when you close the lid, or press the power or sleep button. You can access the Power button controls by following these steps:
Click the Start button, and then choose Control Panel from the menu.
The Control Panel window appears.
In the Control Panel window, click the Power Options icon.
The Power Options Properties dialog box appears.
Click the Advanced tab in the Power Options Properties dialog box.
What you see looks something like this:
You can control three items: the laptop's lid-closing action, the power button, and the sleep button.
For each of the power buttons (and lid), choose an appropriate action.
For each item, you have five choices for what to do:
Do nothing: Nothing happens. This option is preset on every Congressman's laptop.
Ask me what to do: Although this option isn’t available to those snooty Windows Vista users, choosing it directs Windows to display the Turn Off Computer message (refer to the below figure). You can choose what to do from that menu. Note that this option is obviously not available for when you close the laptop's lid.
Stand by: The computer goes into Stand By mode.
Hibernate: The computer hibernates.
Shut down: The computer shuts down Windows and then turns itself off.
Note that not all the options listed in this section may be available. It all depends on your laptop's design and whether the manufacturer has enabled certain functions. In other words, don't get all bent out of shape just because an option isn't on your laptop!
Click OK when you’re done.
