Function Description of ACPI Keys
PowerKey is an ACPI (Advanced Configuration and Power Interface) driver to improve the ACPI functionality performed by Windows operating system, since Windows 95, Windows 98, and Windows NT 4.0 operating systems do not fully support ACPI functions.
You have to enter the BIOS menu to enable ACPI function and to set [Wake up] key to be the power-on key. Due to different models of motherboards, the option names in the BIOS menu are different also. Here we take the one of the motherboards as an example. The following are the steps for setting BIOS. You may take them for your reference.
There may be three ACPI keys on the keyboard:
Power off
When [Power off] key is pressed, a confirmation dialog box is displayed on the screen. After you click 'Y', the Windows operating system will be closed and the three LED indicators on your keyboard will be off.
Pressing [Wake up] key can power on the system.
Sleep
When [Sleep] key is pressed, the system will suspend and enter into power-saving mode. The Windows operating system is not closed. You may press any key to return to your previous running status.
Windows NT4.0 doesn't support the Suspend feature, so this key doesn't work when running under Windows NT 4.0.
Wake up
When [Wake up] key is pressed, the system will wake up. Make sure you have set up the motherboard BIOS. Please refer to the Installation section.
