Abstract: An information handling system includes a processor, an embedded controller (EC) and a battery system. The EC sends a request to the processor based upon a temperature of the battery system. The request includes power limit recommendation that is received by the processor. The processor adjusts a workload based upon the received power limit recommendation from the EC. The adjustment in the workload may correspond to a decrease in discharging rates of the battery system.

Abstract: An information handling system operating a chassis temperature control system may comprise an integrated circuit operatively connected to a proximity sensing strip and a processor, a temperature sensor measuring an exterior temperature of a portion of a chassis of the information handling system adjacent to the proximity sensing strip, and an orientation sensor measuring an orientation of one portion of the chassis to another portion of the chassis to indicate a laptop physical configuration of the information handling system. The integrated circuit may measure a capacitance across the proximity sensing strip such that a high capacitance measurement results in a low skin temperature limit setting, and the processor may execute code instructions of the chassis temperature control system to incrementally decrease a processor power draw limit level based on the exterior temperature measurement exceeding the low skin temperature limit setting.

Abstract: An information handling system (IHS) includes an ion emitter/collector blower cooling system including an ion emitter and an ion collector, the ion emitter/collector blower system being placed at a location within a chassis of the IHS vertically lower than the hardware processor in the chassis. The IHS includes an ionic driving circuit operatively coupled to the ion emitter via a high voltage to ionize gases within the ion emitter/collector blower housing and create charged ions that generate an airflow along a voltage field to and through an ion collector. The IHS includes an air inlet vent located below the ion emitter/collector and formed in a back surface of the chassis of the IHS and an air exhaust vent located at an upper exhaust vent location above the ion collector within the chassis of the IHS so that the airflow is brought into the chassis of the IHS via the ion emitter/collector cooling system and out of the air exhaust vent where a location of the air inlet vent relative to the upper exhaust vent location of the air exhaust vent in the chassis of the IHS in a vertical orientation provides convection-enhanced airflow.
