Abstract:
1. A portable electronic apparatus with a power saving function, comprising: a data storage for storing a work mode table that defines a plurality of operation commands and work mode of the operation commands; an input device provided for inputting an operation command; a CPU (central processing unit); a power control unit for controlling power supply of power consuming components excepting the CPU, the input device, the power control unit, and the data storage; and a power unit for supplying power directly to the CPU, the input device, the power control unit, and the data storage; wherein, the CPU comprises: an operation command receiving module for receiving the operation command transmitted from the input device; a work mode detection module for obtaining a new work mode which corresponds to the operation command from the work mode table; a work state detection module for determining component work state changes of the power consuming components from a current work mode to the new work mode; and a work state updating module for signaling the power control unit to change the component work states of the power consuming components according to the determination of the work state detection module.
