Abstract:
1. A method of managing the power up of a device that has a power down state, at least two power up states, and a run state, wherein the method comprises: statistically analysing a power up time profile of the device; determining one or more predetermined statistical indicators associated with the power up time profile; calculating an anticipated time for a user power up of the device to the run state based on the one or more predetermined statistical indicators; at a predetermined amount of time before the anticipated time for the user power up of the device, changing a device state from the power down state to a first predetermined power up state of the at least two power up states in response to the predetermined amount of time being less than a first threshold, and changing the device state from the power down state to a second predetermined power up state of the at least two power up states in response to the predetermined amount of time being more than the first threshold and less than a second threshold; and powering up the device from the first predetermined power up state or the second predetermined power up state to the run state during the user power up in response to a user interaction with the device during a predetermined duration, otherwise maintaining the device at the predetermined one of the at least two power up states for the predetermined duration and then returning the device to the power down state if there is no user interaction with the device during the predetermined duration.
