Abstract
A power supply for a computer system manager, wherein the power supply has its own secondary power source operable when primary input power to the system manager no longer meets preset threshold values. The power supply monitors the primary input power as well as the secondary power source. Further, the power supply includes a regulating circuit which maintains the power emitted by the secondary power source to within a very narrowly defined voltage range. The power supply regulates the secondary power source while the secondary power source is being used by the computer system manager and while the primary input power is being used by the computer system manager. The power supply switches among power modes to conserve secondary power while the secondary power source provides power. The power supply includes a charger for the secondary power source.
