Abstract: A thermal protection method for a computer system including at least a processor includes monitoring the temperature and loading of the processor via a system firmware in the computer system, obtaining the current performance state level and at least an operable performance state levels of the processor when the system firmware determines that the temperature and loading of the processor exceeds a predetermined value respectively, wherein the performance state level is associated to the frequency of the processor, and setting the processor to one of the operable performance state levels, wherein the frequency of the performance state level is lower than the frequency of the current performance state level, according to the current performance state level and the operable performance state levels.

Abstract: Power consumption control method for an electronic system determines whether an external device is plugged in one of the connection ports of the electronic system by detecting the variation of average power consumption of the electronic system. The one connection port with plugged external device is then turned on and provided with power, making the external device workable. The external device may further be charged after confirmation of connection to the connection port. Completion of charging and status of unplugging of the external device may further be acquired in the electronic system by also detecting the variation of average power consumption, which will subsequently turn off the charger circuit and the connection port for substantially saving power consumption and prolonging the battery time.
