SYSTEM AND METHOD FOR LIMITING BATTERY CHARGING DURING STORAGE AND SHIPPING STATES
First Claim
1. An information handling system operating a BMU controller comprising:
- a rechargeable battery;
a BMU controller to determine battery charge percentage value;
a memory device for storage of a first internal data record indicating a first power-on event; and
the controller operatively coupled to the memory device and the rechargeable battery;
the controller executing machine-readable executable code instructions to determine the memory device contains no first internal data record indicating the first power-on event, and to limit voltage received by the rechargeable battery such that the percentage value charge of the rechargeable battery does not exceed a first set percentage value charge limit; and
the controller receiving machine-readable executable code instructions operable to record the first internal data record in the memory device indicating the first power-on event when a processor and a main memory of the information handling system are next powered on from an off state.

Abstract
An information handling system operating a BMU controller may include a rechargeable battery, a BMU controller to determine battery charge percentage value, a memory device for storage of an internal data record indicating a first power-on setting, and the controller operatively coupled to the memory memory device and the rechargeable battery. The controller executing machine-readable executable code instructions to determine that the main memory contains no internal data record indicating a first power-on event and to limit the voltage received by the rechargeable battery such that percentage value of the charge of the rechargeable battery does not exceed a set percentage value charge limit during storage and shipment of the information handling system. The controller also receiving machine-readable executable code instructions operable to record an internal data record in the memory device indicating a first power-on event when the processor and main memory of the information handling system are next powered on from an off state and upon storing the internal data record indicating a first power-on setting to remove the set percentage value charge limit and allow the rechargeable battery to charge to full capacity.

8. A method for limiting battery charging of an information handling system comprising:
-
determining a memory device operatively coupled to a BMU controller contains no first internal data record indicating a first power-on event; limiting voltage received by a rechargeable battery, via the BMU controller, such that the percentage value of the charge of the rechargeable battery does not exceed a first set percentage value charge limit; and receiving code instructions operable to record a first internal data record in the memory device indicating the first power-on event when a processor and main memory of the information handling system are next powered on from an off state and upon storing the first internal data record indicating the first power-on event to remove the first set percentage value charge limit and allow the rechargeable battery to charge to full capacity. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An information handling system operating a battery management unit controller comprising:
-
a rechargeable battery; a BMU controller to determine battery charge percentage; the BMU controller operable to record a first power-on event due to a next occurrence of a processor and main memory of the information handling system being powered on from an off state after shipping after a first power-on setting is set to detect the next occurrence of the processor and main memory being power on from an off state; a memory device operatively coupled to the BMU controller; the BMU controller executing machine-readable executable code instructions such that upon determining that the memory device contains no first internal data record indicating the first power-on event, to limit voltage received by the rechargeable battery such that the percentage value charge of the rechargeable battery does not exceed a first set percentage value charge limit; and the controller executing machine-readable executable code instructions such that upon determining that the memory device has recorded the first internal data record indicating the first power-on event, removing the first set percentage value charge limit allowing the rechargeable battery to charge to full capacity. - View Dependent Claims (16, 17, 18, 19, 20)
