Publication number: 20220171446Abstract: Techniques for allocating power budget to a central processing unit (CPU) of a computing device are described. According to an example of the present subject matter, an unloaded component is detected. The unloaded component remains undetected upon completion of a boot process of the computing device. Thereafter, a power budget allocated to the unloaded component is determined. The power budget may be based on the thermal design power (TDP) of the computing device. Based on the power budget, a power configuration of the CPU is changed from a default power level to a high-performance power level, wherein the default power level corresponds to the TDP of the computing device and the high-performance power level is a power level above the default power level and upto a maximum power level of the CPU.Type: ApplicationFiled: July 31, 2019Publication date: June 2, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Yen Tang Chang, Chao Wen Cheng, Chien Chen Su, Po Ying Chih

Publication number: 20220147129Abstract: Techniques for reallocating power between a plurality of electronic components and a connection port of a computing system are described. In operation, operational state of an electronic component from amongst multiple electronic components is analysed. Based on the operational state of the electronic component, an unused power available with the electronic components is determined. Based on the availability of the unused power, a default power level associated with the connection port is increased, where the default power level is a predefined power allocated to the connection port for operation.Type: ApplicationFiled: July 31, 2019Publication date: May 12, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Chao Wen Cheng, Po Ying Chih, Yen Tang Chang

Publication number: 20220147127Abstract: Techniques for allocating power budget to a central processing unit (CPU) of a computing device are described. According to an example of the present subject matter, a CPU is operated at default power level corresponding to a thermal design power (TDP) of the computing device. Thereafter, an unused power of the computing device is determined at run-time. The unused power is a difference between an allocated power budget of the component and current power consumption of the component, wherein the allocated power budget is an amount of power allocated to the component based on the TDP of the computing device. Based on the unused power the CPU is operated at a high-performance power level. The high-performance power level is a power level above the default power and up to a maximum power level of the CPU.Type: ApplicationFiled: July 31, 2019Publication date: May 12, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Po Ying Chih, Chao Wen Cheng, Yen Tang Chang, Wei Chieh Liao, Yu Fan Chen, Chien Chen Su
