Apple's Patent Background

Many computing devices are equipped with power saving features/modes intended to reduce power consumption when a user is not using the devices. Often, these power saving features are implemented though timers that count down a set amount of time from when the user last provides an input to the device. For example, a particular device may be configured to enter a sleep mode, or other mode that consumes less power than a fully operational mode, when a user has not provided input for five minutes.
