A method and apparatus for extending peak power capability of a computing device. In one embodiment, the apparatus comprises: voltage monitoring hardware to monitor voltage being supplied by a battery to a system load; and an energy storage coupled to the voltage monitoring hardware and/or charging scheme to supplement supply of power to the system load when the voltage supplied to the system load by the battery, as monitored by the voltage monitoring hardware, drops below a first threshold voltage level, the first threshold voltage level being above a minimum voltage level associated with the computing system.
