Patent ID: 8138722

Claim:
An information handling system, comprising: a processor; a memory communicatively coupled to the processor; and a power supply system configured to supply power to one or more particular components of the information handling system, the power supply system comprising: a battery; one or more switches maintained in a ship mode state during shipping of the information handling system, wherein the ship mode state of the one or more switches decouple the battery from the one or more particular components; a battery management unit (BMU) configured to control the one or more switches; and a power-on device operatively coupled to the BMU and configured to generate and communicate a power-on signal to the BMU in response to a user activation of a power button; and the BMU further configured to activate the one or more switches from the ship mode state in response to receiving the power-on signal, wherein activating the one or more switches from the ship mode state couples the battery to the one or more particular components; wherein the power-on device generates and communicates the power-on signal to the BMU, and the BMU activates the one or more switches from the ship mode state, while the information handling system is not coupled to any power source other than the battery; wherein the power-on device is operatively coupled to the BMU via a pin of the battery.
