A method is described that involves operating a computing system within a
normal on state and transitioning from the normal on state to a main
CPU/OS based state. In the main CPU/OS based state one or more components
of the computing system are inactivated so as to cause the computing
system to consume less power in the main CPU/OS based state than in the
normal on state. The computing system is able to execute software
application routines on a main CPU and a main OS of the computing system
while in the main CPU/OS based state.
