Abstract
An uninterruptible power supply system and method for an information handling system provides an internal power storage device for supplying power to an information handling system and a detector for detecting the condition of an external power supply and/or the power level of the internal power storage device, wherein the power management system prevents the information handling system from resuming operation until the detector detects that an external power supply has been stable for a predetermined period of time and/or that the power level of the power storage device is sufficient to permit the information handling system to perform a data saving function.
