help !How do i find the "hibernate" button on my desktop? it disappeared!?

Why can't I find the sleep or hibernate options on my computer?

Click the Start button , and then click the arrow next to the Shut down button.

Sleep and Hibernate located on the menu

If sleep or hibernate aren't available, it might be for one or more of the following reasons:

Your video card might not support sleep. Update the driver for your video card, or check the information that came with your computer about your video card and supported drivers. For more information, see Update drivers: recommended links.

Some settings are managed by your system administrator. For more information, see Why won't Windows allow me to change a system setting?

Sleep and other power-saving states are turned off in your computer's basic input/output system (BIOS). To turn on sleep, restart your computer, and then enter the BIOS setup. As your computer starts, instructions typically appear on the screen that indicate which key or keyboard shortcut you must press to enter the BIOS setup process. Because not all computer manufacturers use the same BIOS, different keys are assigned for this purpose. To learn more, check the information that came with your computer or go to the manufacturer’s website.

If the hibernate option is missing, you might have hybrid sleep turned on.

You go to the FN letter/key on the bottom of the key board close to the space bar and ctrl and alt on your left then click and hold and then you will see the hibernate thing or sorry but you can also simply click on F4.

Always be suspicious of free cleanups, especially online. When taking it to a store, ask in detail what they will do.

Try pressing shift or control, might make "Standby" switch over. What OS are you running? XP Vista or 7?
