Abstract
In some embodiments, a method for activating an information handling system battery without using AC power is provided. One or more switches associated with a battery are maintained in a ship mode state during shipping of the information handling system such that the battery remains disconnected from particular information handling system components during shipping. In response to a user input, a power-on device generates and communicates a power-on signal to a battery management unit (BMU) of the battery. In response to receiving the power-on signal, the BMU activates the one or more switches from the ship mode state, which connects the battery to the particular information handling system components. 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 connected to any AC power source.
