Abstract
An information handling system (IHS) may include a battery management unit (BMU) that remains operational when the IHS in general is in a powered off state. A processor is operational when the IHS in general is in a powered on state but not when the IHS in general is in a powered off state. The BMU is configured to obtain charge and discharge pattern information while the IHS in general is in the powered off state, to transmit the charge and discharge pattern information to the processor when the IHS in general is in the powered on state, to receive user control information from the processor, and to control charge and discharge of a battery according to the user control information when the IHS in general is in the powered off state.
Claims20
A method comprising:
- obtaining charge and discharge pattern information at a battery management unit (BMU) while an information handling system (IHS) is in a powered off state;
- transmitting the charge and discharge pattern information from the BMU to the IHS when the IHS is in a powered on state;
- receiving user control information from the IHS when the IHS is in the powered on state;
- and
- controlling, by the BMU, charge and discharge of the battery of the IHS according to the user control information when the IHS is in the powered off state.
An information handling system (IHS) comprising:
- a battery;
- a battery management unit (BMU) connected to the battery, the BMU remaining operational when the IHS in general is in a powered off state;
- and
- a processor operational when the IHS in general is in a powered on state but not when the IHS in general is in a powered off state, wherein the BMU is configured to obtain charge and discharge pattern information while the IHS in general is in the powered off state, to transmit the charge and discharge pattern information to the processor when the IHS in general is in the powered on state, to receive user control information from the processor, and to control charge and discharge of the battery according to the user control information when the IHS in general is in the powered off state.
A method comprising:
- sending, at an information handling system (IHS), a charge and discharge pattern to a battery management unit (BMU);
- storing, at the BMU, the charge and discharge pattern;
- setting the IHS to a powered off state;
- detecting, at the BMU and when the IHS is in the powered off state, connection of a charger to the IHS;
- determining, at the BMU and when the IHS is in the powered off state, based on the charge and discharge pattern, whether a battery of the IHS needs charging;
- when the battery needs charging, charging the battery;
- and
- when the battery does not need charging, disabling a charging circuit.
