Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. A method comprising:
determining an initial PSU power level at a startup of the device;
limiting an output power of a charger using a charger current limit input to the charger and determined based at least in part on the initial PSU power level at the startup of the device;
receiving internal temperatures of a power supply unit (PSU) over a duration of time;
determining an exponential weighted moving averages (EWMA) of the internal temperature of the PSU for the duration of time;
comparing the EWMA with a temperature threshold associated with the duration of time; and
based at least in part on determining that EWMA exceeds the temperature threshold associated with the duration of time, limiting the output power of a charger using the charger current limit input to the charger.
