ABSTRACT:
A power supply (1) is for an electrical load in the form of a Notebook computer (2). Power supply (1) includes first terminals (3, 4) which extend from computer (2) for releasably electrically connecting with a first energy storage device in the form of battery (5) during a first interval. A second energy storage device, in the form a second battery (not shown), releaseably electrically connects with terminals (3, 4) during a second interval spaced apart from the first interval. This allows power to be supplied to the load during those intervals. A capacitive energy storage device, designated generally by reference numeral (6), supplies power to the load during a third interval that spans the spacing between the first and the second intervals.
