Abstract
An information handling system includes a battery, a host processing complex, and a management system. The battery includes a battery power level gauge that determines a power level of the battery. The management system includes a wireless transceiver. When the host processing complex is unpowered, the management system is coupled to receive power from the battery and provides a first indication of the power level of the battery via the wireless transceiver.
Claims18
An information handling system, comprising:
- a battery including a battery power level gauge that determines a power level of the battery;
- a processor;
- and
- a management system including a baseboard management controller (BMC) and a wireless transceiver, wherein when the processor is unpowered, the BMC is coupled to receive power from the battery, the BMC provides a first indication of the power level of the battery via the wireless transceiver to a mobile device, and sets a second indication for use by the processor during a pre-boot operation when the processor is subsequently powered on, wherein the BMC provides the first indication when the power level of the battery is below a first threshold;
- wherein the information handling system detects the second indication during the pre-boot operation, and shuts down the pre-boot operation and provides an error indication in response to detecting the second indication.
A method, comprising:
- determining a power level of a battery of an information handling system;
- coupling a baseboard management controller (BMC) to receive power from the battery when a processor of the information handling system is unpowered;
- providing, by a wireless transceiver coupled to the BMC, a first indication of the power level of the battery to a mobile device, wherein the BMC provides the first indication when the power level of the battery is below a first threshold;
- setting, by the BMC, a second indication for use by the processor during a pre-boot operation when the processor is subsequently powered on;
- detecting, by the information handling system, the second indication during the pre-boot operation;
- shutting down, by the information handling system, the pre-boot operation in response to detecting the second indication;
- and
- providing, by the information handling system, an error indication in further response to detecting the second indication.
A non-transitory computer-readable medium including code for performing a method, the method comprising:
- determining a power level of a battery of an information handling system;
- coupling a BMC to receive power from the battery when a processor of the information handling system is unpowered;
- providing, by a wireless transceiver coupled to the BMC, a first indication of the power level of the battery to a mobile device, wherein the BMC provides the first indication when the power level of the battery is below a first threshold;
- setting, by the BMC, a second indication for use by the processor during a pre-boot operation when the processor is subsequently powered on;
- detecting, by the information handling system, the second indication during the pre-boot operation;
- shutting down the pre-boot operation in response to detecting the second indication;
- and
- providing an error indication in further response to detecting the second indication.
