The standby power supply control device is switched to supply power. If the standby power supply is still problematic after further detection, the user is reminded that there is a problem with the power supply of the computer, and maintenance should be performed as soon as possible.

By calculating the impeller efficiency of the cooling fan and comparing it with the efficiency under normal test mode, it can be determined whether the cooling system is working normally, reducing the risk of performance degradation and hardware damage caused by poor cooling. According to the temperature of the GPU and CPU, the power supply value of the cooling fan is dynamically adjusted. In low load conditions, the power supply value of the cooling fan can be reduced to a minimum, thereby reducing energy consumption. Not only prolongs the use time of the notebook, but also reduces power consumption, thereby reducing operating costs and playing a positive role in environmental protection. Intelligent adjustment can maintain the best energy efficiency balance under real-time environmental conditions, allowing users to enjoy the dual advantages of performance and energy saving.
