Staged power distribution control
First Claim
1. An apparatus comprising:
- logic, at least a portion of which is implemented in hardware, the logic to;
send a first control signal to a component of a computing device based on a detection that a voltage level has fallen below a first voltage threshold, the first control signal to include an indication to take a first action to reduce electric power;
send a second control signal to the component based on a detection that the voltage level has risen above the first voltage threshold and a debounce period has expired, the second control signal to include an indication to undo the first action; and
send a third control signal to the component based on a detection that the voltage level has fallen below a second voltage threshold lower than the first voltage threshold, the third control signal to include an indication to take a second action to reduce electric power;
the first action to reduce an amount of electric power consumed by the component while enabling the component to provide first feature and the second action to reduce an amount of electric power consumed by the component while disabling the component to provide the first feature.

Abstract
Various embodiments are directed to restrictions in portable computing device electric power to accommodate reductions in the voltage level of a power source. An apparatus comprises a controller caused to receive configuration data from a main processor circuit specifying a voltage level threshold and selected action to take to reduce electric power to a first component in response to the voltage level falling below the first voltage level threshold, recurringly monitor the voltage level; based on the voltage level falling below the first voltage level threshold, take the first selected action and transmit a signal to the main processor circuit indicating that the voltage level has fallen below the first voltage level threshold and that the first selected action has been taken; transmit the voltage level to the main processor circuit; receive a signal from the main processor circuit to undo the first selected action; and so undo.
