Abstract
Methods, systems, and computer programs encoded on computer storage medium, for polling a battery management unit (BMU) that is coupled to a battery power source, the polling including identifying parameters associated with the battery power source and are stored by registers; determining that an AC power source is not actively providing power to the IHS; determining that the battery power source does not support dynamic battery power technology (DBPT); determining that the RSoC of the battery power source is greater than a first threshold percentage and less than a second threshold percentage; determining an updated processor peak power (PPP) value based on i) the RSOC, ii) a minimum PPP of the processor at the first threshold percentage, and iii) a maximum PPP of the processor at the second threshold percentage; and updating the registers based on the updated PPP.
