摘要

A method for implementing a power saving function of the portable electronic apparatus is provided. The method includes the step of: receiving an operation command transmitted from an input device; obtaining a new work mode which corresponds to the operation command from a work mode table that defines a plurality of work modes of the portable electronic apparatus and a plurality of operation commands corresponding to the work modes, if a current work mode of the portable electronic apparatus does not correspond to the operation command; determining component work state changes of components of the portable electronic apparatus from the current work mode to the new work mode; signaling a power control unit to change component work states of the components according to the determined component work state changes.
