Abstract
A method comprises: determining whether an external wireless power (EWP) source is coupled to an interface configured to transfer power from the EWP source to the power management (PM) system; selecting the EWP to power the computer mouse when the EWP source is electrically couples and provides power to the interface; determining whether a fixed internal power source (PS) is coupled to the PM system; selecting a fixed internal PS to power the computer mouse when the fixed internal PS is coupled to the PM system and the EWP source is coupled to but not providing enough power to the interface; determining whether a removeable internal PS is electrically coupled to a PM system in the computer mouse; and selecting the removeable internal PS to power the computer mouse when the removeable internal PS is electrically coupled to the PM system and the EPS is not coupled to the interface.
