Activating an information handling system battery from a ship mode

A power supply system for an 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;
• 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, the power-on signal generated in response to a user activation of a power button, 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.

A method for activating a battery of an information handling system without using AC power, the method comprising:

• maintaining one or more switches associated with a battery 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 one or more particular information handling system components;
• in response to a user activation of a power button, a power-on device generating and communicating a power-on signal to a battery management unit (BMU) of the battery;
• and
• the BMU activating 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 information handling system 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.
