Problems solved by technology

The reason why the no-load power of the traditional power supply 1 is difficult to reduce is because it assumes that the load exists at any time, even if the power supply 1 is not actually connected to the load, as long as the power supply 1 is connected to the AC power, the power supply 1 That is, keep it in working condition at any time, and its operating frequency is fixed at about 100KHz
[0005] In practical applications, since the power supply 1 has been widely used in various portable electronic devices 2, when the user leaves the seat and takes the portable electronic device 2, he often does not remember to switch the AC power of the power supply 1 The plug is pulled out, causing the power supply 1 to continue to consume no-load power
Usually the average standby power of a power supply 1 is about 0.3W, since there may be tens of thousands of power supplies 1 in the standby state at any time all over the world, accumulating over a long period of time will cause a very considerable waste of electric energy

Abstract

The invention discloses a computer system, a power supply and a power supply management method thereof. The computer system comprises the power supply and a portable electronic device, wherein the portable electronic device comprises a first control unit and a variable output unit; the first control unit controls the variable output unit, so that the variable output unit provides different outputs; the power supply comprises a power supply circuit, a detection pin, a detection unit and a second control unit, wherein the power supply circuit is connected with the portable electronic device; the detection pin is connected with the output end of the variable output unit; the detection unit is connected with the detection pin to obtain a detection value; the detection value changes along with the output of the variable output unit and the condition whether the power supply is connected with the portable electronic device; and the second control unit is connected with the power supply circuit and the detection unit and controls the operation of the power supply circuit according to the detection value. By using the computer system, no load power can be effectively reduced and the work efficiency when a light load is connected is improved, so that the effects of saving energy and saving electric power are achieved.

Description

technical field [0001] The invention relates to power management of a computer system, in particular to a computer system, a power supply and a power management method thereof. Background technique [0002] In recent years, with the continuous advancement of computer technology, various computer equipment (such as desktop computers and notebook computers) on the market have also been continuously introduced. Among them, notebook computers have the advantages of small size, light weight and easy portability. It has gradually become the first choice for most consumers in the modern busy industrial and commercial society when purchasing computers. [0003] Generally speaking, when a consumer uses a notebook computer, he usually connects to a mains power supply through a power supply to supply power to the battery of the notebook computer. Please refer to figure 1 , figure 1 Shown is a schematic diagram of a traditional notebook computer system supplying power to a portable e...
