Problems solved by technology

However, as far as the prior art is concerned, the operation mechanisms of the fan in the portable device and the fan in the docking station are usually independent of each other.
Therefore, the prior art cannot coordinate the rotation speeds of the two fans according to the operating state of the portable device, thereby affecting the operating performance of the portable device.
In addition, when the two fans operate at the same time, the two fans tend to generate a lot of noise, causing discomfort to the user

Embodiment Construction

[0030] figure 1 and figure 2 Each is a schematic structural diagram of an electronic device according to an embodiment of the present invention. Such as figure 1 As shown, the electronic device 10 includes a portable device 100 and a docking station 200 . Wherein, the portable device 100 is, for example, a tablet computer (Tablet PC) or a portable device with independent computing and display functions, and the type of the portable device 100 is not limited here. In addition, the portable device 100 is suitable for being detachably assembled on the docking station 200 . For example, the docking station 200 includes a groove 201 , and the portable device 100 can be inserted into the groove 201 to be electrically connected with the docking station 200 . Furthermore, if figure 2 As shown, the portable device 100 can also be detached from the docking station 200 to be electrically separated from the docking station 200 .

[0031] In other words, the portable device 100 can...

Abstract

The invention relates to a fan control method suitable for an electronic device comprising a portable device and an expansion pedestal. The portable device comprises a first fan. The expansion pedestal comprises a second fan. The fan control method comprises the following steps of determining whether sensing signals from the expansion pedestal are received or not, so as to switch a portable device to a laptop mode or a tablet mode; and dynamically adjusting the rotation speed of the first fan and the second fan according to a first noise temperature comparison table and an internal temperature value of the portable device under the laptop mode.

Description

technical field [0001] The present invention relates to an electronic device and its fan control method, and in particular to an electronic device with a portable device and an expansion base and its fan control method. Background technique [0002] Portable devices (for example: tablet computers) can expand their functions by combining with the docking station. In addition, when the portable device is combined with the docking station, the portable device can also use the fan in the docking station to dissipate heat in addition to its internal fan. However, as far as the prior art is concerned, the operation mechanisms of the fan in the portable device and the fan in the docking station are usually independent of each other. Therefore, the prior art cannot coordinate the rotation speeds of the two fans according to the operating state of the portable device, thereby affecting the operating performance of the portable device. In addition, when the two fans operate at the s...
