Î APM 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.
