WWAN Radio Power Management (MC9062/MC9063 Only)

The radio's power state is not dependent on the mobile computer's power state. In addition to its own

power state, the radio has automatic internal power management to preserve battery life when the

radio is on and not in use.

In its default state, the radio can remain on during a suspend and resume of the mobile computer. To

change the default radio state, use registry keys to configure on/off power during a suspend and

resume of the mobile computer.
