Abstract:
An information handling system including a processor; a battery; a charger module a voltage regulator module connected between the charger module and the processor, the voltage regulator module configured to receive power from the charger module and provide a regulated voltage to the processor; a OVP module configured to determine that the regulated voltage output from the voltage regulator module is above a first threshold, and in response, provide a first signal to the charger module to indicating that the regulated voltage is above the first threshold; a UVP module configured to determine that the charger voltage output from the charger module is below a second threshold, and in response, provide a second signal to the charger module indicating that the charger voltage is below the second threshold, wherein the charger module, in response to receiving both the first signal and the second signal, changes to an off power state.
