ÎAPM Mode

APM is briefed from Advanced Power Management. The energy-saving standby mode is initiated in the following ways:

•Time-out period specified in the BIOS Setup Utility

•Commands from the operating system, such as the Suspend menu item in your operating system

•In standby mode, the SBC reduces power consumption by using the SMM capabilities. Reducing power to or turning off Video Electronics Standards Association (VESA) Display Power Management Signaling (DPMS)-compliant monitors and spinning down hard disks.

One noticeable point is that the operating system must support an APM driver for the power-management features to work.
