Description

Technical Field

[0001] The present invention relates to the technical field of computer power consumption settings, and more particularly to a method and device for automatically adjusting computer power consumption settings. Background Art

[0002] In traditional computer settings, the BIOS sets the computer's PL1, PL2, and PL4 to meet the maximum power consumption of the adapter (power adapter). Once set, the client cannot change the setting value, and the computer system must be used with a PSU (power supply unit) with a fixed power consumption. Users need a power adapter with a fixed power consumption and model, which loses the portability of the computer system. At the same time, due to this fixed parameter setting, it will cause more serious problems in some scenarios. For example, if the computer adapter is shared with other devices and the PSU power consumption is insufficient, it will cause the computer system to automatically power off, which cannot meet the needs of flexible application scenarios. To solve this problem, a method and device for automatically adjusting computer power consumption settings are needed. Summary of the Invention
