Problems solved by technology

[0002] As we all know, the CPU heat dissipation of all-in-one machines and notebooks needs to be dissipated by fans, but after the fans run for a period of time, dust will accumulate on the sides of the PCB board and air inlets and other air ducts, resulting in problems with CPU heat dissipation

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 and figure 2 , when the notebook is running and shutting down in the S2 state, the EC will detect whether the dust removal button is pressed, if not, the system enters the S5 state. Enter the S2 state and press the clear key, then in the S3 state, the EC will notify to open K2, and turn on the reverse power switch of the notebook fan. In S4 state, when the fan enters the reverse state, the EC will enter the countdown. If the interrupt button is pressed at this time, the fan will stop immediately and enter the S5 state. Otherwise, the EC will turn off K2 and the system will automatically enter the S5 state until the timer is over. .

[0016] Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modificat...

Abstract

The invention discloses a notebook computer and all-in-one machine dust removal method. Two fan bodies are arranged on a heat radiating fan of a CPU, in other words, a forward rotation switch K1 and abackward rotation switch K2 are included, and the forward rotation switch K1 and the backward rotation switch K2 are connected with a fan power source according to the selected state. The notebook computer and all-in-one machine dust removal method has the following advantages that in the prior art, under the condition of shutdown, a hot key is pressed down to notify an EC to start the fan powersource, the fan inversely rotates, air is pumped to an air inlet from an air outlet end, inversed flowing of the air direction enables dust originally attached to the surface is brought out of a hostmachine through air, and the effect of dust removal is achieved.

Description

technical field [0001] The invention relates to a method for processing dust on PCB board edges and air inlets, in particular to a method for removing dust from notebooks and all-in-one machines. Background technique [0002] As we all know, the CPU cooling of all-in-one machines and notebooks needs to be cooled by fans, but after the fan runs for a period of time, dust will accumulate on the sides of the PCB board and air inlets, which will cause problems in CPU cooling. The current notebooks basically rely on artificial cleaning of radiators and air ducts. [0003] In the prior art, the application number is CN201720322545.3, and the name is a computer CPU heat sink dust removal device, which discloses a scheme, specifically: a computer CPU heat sink dust removal device, which is installed in a computer case and used for a computer host CPU The cooling fins of the radiator are used for dust removal. The CPU radiator is installed on the CPU of the motherboard on the comput...
