More Information

The ability to recover from sleep mode by pressing a key on the keyboard or by moving the mouse on a computer that supports ACPI is dependent on the computer's motherboard. This ability is disabled in older Intel motherboards, and the only way to wake the computer from sleep mode is to press the Power button.

With most newer motherboards, you can wake the computer by pressing the Power button, by pressing a key on the keyboard, or by moving the mouse.

ACPI support is necessary to take full advantage of the power management and Plug and Play features in Windows. If you are not sure whether your computer is ACPI-compliant, please see the printed documentation for your computer or motherboard, or contact the manufacturer of your computer or motherboard.
