Method and apparatus for user-activity-based dynamic power management and policy creation for mobile platforms
First Claim
1. A method comprising:
- operating a computing device according to a first power management policy;
monitoring one or more sensor values of the computing device;
predicting a new user state according to the monitored sensor values and an updated user state model; and
switching from the first power management policy to a second power management policy if the new user state differs from a present user state by a predetermined amount.

Abstract
A method and apparatus for user activity-based dynamic power management and policy creation for mobile platforms are described. In one embodiment, the method includes the monitoring of one or more sensor values of a mobile platform device to gather sensor activity data. Once the sensor activity data is gathered, the user state may be predicted according to the gathered user activity and an updated user state model. In one embodiment, the user state model is updated according to the sensor activity data. In one embodiment, a switch occurs from the present power management policy to a new power management policy if the new user state differs from a present user state by a predetermined amount. In one embodiment, at least one time-out parameter of a selected power management policy may be adjusted to comply with a predicted user state. Other embodiments are described and claimed.

16. A system comprising:
-
a clock to trigger a new user state alarm; a direct current (DC) power source, wherein the DC power source couples to the clock; a processor coupled to the DC power source, the processor having at least one power state condition to cause the processor to perform at a selected operating mode; and a chipset coupled to the processor, the chipset including power management logic configured to predict a new user state in response to the triggered user state alarm by monitoring one or more sensor values, to select a new power management policy if the predicted user state differs from a previous user state and to switch from a current power management policy to the new power management policy. - View Dependent Claims (17, 18, 19, 20)
