A power regeneration system for a portable electronic device employs a mechanical energy converter for converting mechanical energy generated by activating keys in the keyboard and other manual operators employed in the portable computer into electrical energy. The mechanically generated electrical energy is used to power a transmitter or to recharge a rechargeable battery in the portable computer through a charging circuit. Time between charges of the rechargeable battery from external AC sources is extended due to the recapture of the mechanical energy generated through normal operation of the portable computer.
