Abstract: An information handling system includes a battery and a charger. The battery provides a battery voltage to a main power rail of the information handling system and is couplable to the main power rail through a switch. The charger has an output coupled to the main power rail and an input coupled to an external power adapter. The power adapter provides a selectable voltage level to the input. The information handling system selects a particular voltage level that is lower than the battery voltage and directs the switch to decouple the battery from the main power rail when the information handling system is in a soft power-off state.

Abstract: In one or more embodiments, one or more systems, methods, and/or processes may determine that a timeout value has been reached; for each battery cell of multiple of battery cells: may determine if a temperature value associated with the battery cell meets or exceeds a threshold temperature value; if the temperature value associated with the battery cell does not meet or exceed the threshold temperature value, may permit the battery cell to be charged and discharged; if the temperature value associated with the battery cell meets or exceeds the threshold temperature value: may increment a temporary fail count associated with the battery cell; and may prevent at least one of charging and discharging the battery cell; may determine if temporary fail count exceeds a temporary fail count threshold; and if the temporary fail count does not exceed the temporary fail count threshold, may permit charging and discharging the battery cell.

Abstract: An information handling system real time clock (RTC)/CMOS circuit is powered from a battery that powers the information handling system. The battery power is supplied through a power management circuit that manages power constraints to the real time clock and that protects the battery from exceeding current and voltage thresholds. A protection integrated circuit selectively cuts off power supply from a power module to the RTC/CMOS circuit if predetermined conditions are detected. The protection circuit may also cutoff all power from battery with a permanent failure option or may itself directly supply power to the real time clock/CMOS circuit.

Abstract: In one or more embodiments, one or more systems, one or more methods, and/or one or more processes may determine multiple voltage values associated with a rechargeable battery over a period of time; store the multiple voltage values with respect to multiple clock values over the period of time; determine a voltage drop rate from the multiple voltage values and the multiple clock values; determine a threshold voltage value associated with a predicted energy capacity of the rechargeable battery for a mobile information handling system (IHS) to perform a power state transition; determine a voltage value associated with the rechargeable battery; determine that the voltage value has reached the threshold voltage value; provide a notification to an operating system executed by the mobile IHS; store data from a volatile memory medium to a non-volatile memory medium; and transition the mobile IHS from an operational state to a power conservation state.

Abstract: Managing a battery of an information handling system, including determining a degradation factor of the battery based on one or more parameters of the battery; determining a first thermal stress time of the battery over a first time period, including: identifying a voltage of the battery over the first time period; identifying a temperature of the battery over the first time period; calculating the first thermal stress time of the battery over the first time period based on the voltage and the temperature of the battery over the first time period; comparing the first thermal stress time of the battery of the first time period to a time threshold, the time threshold based on the degradation factor of the battery; determining, based on the comparison, that the first thermal stress time of the battery is greater than the time threshold, and in response, adjusting a charge voltage of the battery.
