• 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

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.
