The present invention manages power for state machines. The system and
methods selectively apply, remove and/or reduce power to portions of the
state machine, based on power management schemes, intelligence, a user,
an application, etc. Such novel systems and methods provide for
sustaining a CPU and/or a network radio in an "on" state, while lowering
and/or removing power to other portions of the state machine to reduce
power consumption. The foregoing enables a wireless mobile terminal to
maintain network connectivity and be able to wake to service events such
as a link status change, a network keep alive, a proxy-ARP packets, a
re-authentication packets, etc. Such power management can execute in the
background and return the wireless mobile terminal to a "run" state via
invocation from a wake source such as a power control, a key, a trigger,
a touch screen, a wake up timer, a wake-on-LAN, etc.
