Problems solved by technology

However, I323838 still emphasizes the overheating protection of the central processing unit. For the above-mentioned plastic parts such as the central processing unit socket, the PCB of the motherboard, and the case of the notebook that are directly affected by the system temperature, there is still a lack of an equivalent overheating protection mechanism.

Embodiment Construction

[0026] see figure 1 As shown, it is an electronic device 100 disclosed in the first embodiment of the present invention, and the internal temperature is defined as the system temperature Ts. The electronic device 100 can be a notebook computer, a personal digital assistant, a portable navigation device (PND), a tablet computer or a multimedia player, but does not exclude the electronic device 100 such as a desktop computer or a server.

[0027] The casing, PCB, etc. of the aforementioned devices are usually made of plastic, and their ability to withstand high temperatures is relatively low. When the electronic device 100 is in operation, the system temperature Ts changes with the operating state of the electronic device 100 . Although the system temperature Ts will not affect the high-temperature-resistant electronic components 110 , it may cause damage to the casing and PCB. The electronic device 100 of the present invention monitors the system temperature Ts during operatio...

Abstract

The invention discloses an electronic device and a control method protecting the electronic device. The control method is executed in the electronic device, is used for judging whether the system temperature of the electronic device is overhigh, and enables the electronic device to be switched into low-power operation when the system temperature is overhigh. According to the control method, an electronic element of the electronic device is monitored, current temperature and current power of the electronic element are obtained, and whether the system temperature is overhigh is judged according to the current temperature and the current power. When the system temperature is overhigh, a high-temperature signal is generated, and the electronic device is triggered to enter into a lower-power operation state. Therefore, a temperature monitoring mechanism in the electronic device is simplified, and no sensor used for measuring the system temperature and environmental temperature is needed to be installed additionally.

Description

【Technical field】 [0001] The invention relates to an overheating protection mechanism of an electronic device, in particular to an electronic device and a control method for protecting the electronic device. 【Background technique】 [0002] The system temperature change inside the electronic device is not only affected by its own heating power, but also the ambient temperature will also affect the heat dissipation rate of the electronic device, thereby affecting the system temperature. [0003] In general desktop computers and notebook computers, the motherboard can monitor the operating power and temperature of the CPU. The monitoring of the operating power is used to control the power consumption, and the monitoring of the temperature is used to forcefully shut down and restart the computer in a timely manner, or increase the speed of the cooling fan to prevent the CPU from burning out. For example, the invention of Taiwan Patent No. I327261 is to continuously monitor the ...
