HDMI interface short circuit risk analysis HDMI interface short circuit is a common fault in electronic equipment. If not handled in time, it may cause damage to the interface and even affect the normal use of the equipment. PHP editor Youzi brings you a detailed analysis of HDMI interface short circuit to help you understand its causes, effects and solutions.
Of course it will burn out, but under normal circumstances, the voltage and current of the HDMI interface are not large, so the possibility of burning out is small
Hello: ——★1. If it has been confirmed that "the USB interface is all broken", then it should be a motherboard problem: the plug-and-play controller on the motherboard is damaged.
——★2. It is confirmed that "the USB interface is completely broken". If the motherboard is repaired, it needs to be returned to the factory, which is quite troublesome, takes a long time, and is not economically cost-effective. ——★3. You can buy a PCI to USB adapter card and plug it into the PCI socket. The front USB board is invalid because the plug and play controller is damaged.What cable should I change? Could it be that the USB port on the front of the chassis is short-circuited? Then you can just open the case and unplug the USB cable leading to the front of the case. If the USB interface on the back of the motherboard is short-circuited, it needs to be repaired.
I think this possibility is very small. Open the case and see that there are two sets of red, white, green and black connecting cables leading to the front of the case. Unplug it and try to turn it on. If it can turn on, don't use the front USB interface. Use the one at the back. If it’s inconvenient, just buy a 1-to-4 USB expansion portLaptops are temporarily unavailable;
Desktop computers: You can purchase a PCI USB expansion card and insert it into the PCI slot of the computer. But it needs to be reminded that even if you use a USB3.0 transmission protocol port, it does not mean that you can reach the official 3.0 port transmission speed, because the transmission speed is also affected by many conditions such as computer memory, CPU, and motherboard cache. .
Everyone who uses a computer may You will encounter such a problem: the USB interface of the computer host is faulty. The USB interface is an important interface for us to connect various external devices. Once problems occur, it will bring a lot of inconvenience to our work and life. This article will introduce you to the possible reasons why the USB interface of the computer host is broken and the corresponding solutions. I hope it will be helpful to you.
1. Poor interface contact: After long-term use of the USB interface, the contact points may be damaged or oxidized, resulting in poor contact. In this case, the connector may need to be cleaned or replaced.

2. Update driver: You can try to update the USB interface driver. You can find the relevant driver in the device manager and update it.
3. Replace the interface: If the inspection confirms that the interface is faulty, the damaged USB interface may need to be replaced. You can contact the manufacturer or professional maintenance personnel for replacement.
4. Restart the computer: Sometimes simply restarting the computer can also solve the problem of the USB interface not being recognized. Try restarting the computer and check again whether the interface is working properly.
5. Check the system settings: Find the USB interface related settings in the system settings, make sure the interface is enabled, and check whether the related configuration is correct.
Computer host USB interface failure is a relatively common problem, but it can usually be solved through some simple methods. First carefully check the physical status of the interface, then try updating the driver or cleaning the interface. If the above methods do not solve the problem, you may need to replace the damaged interface or adjust the system settings. I hope this article can help you better solve the problem of computer host USB interface failure and keep our computer equipment in good operating condition.
When we buy a desktop computer host, we are often confused by various specifications and performance parameters Confused, especially the USB interface. The USB interface plays an extremely important role in today's desktop computers, affecting the convenience of using external devices and the speed of data transmission. Therefore, it is crucial to correctly select the desktop computer host USB interface. The following will introduce how to correctly select the desktop computer host USB interface.
Before choosing a desktop computer host USB interface, first we need to understand the types of USB interfaces. The current mainstream USB interfaces are divided into USB 2.0, USB 3.0 and USB 3.1. There are obvious differences between them in terms of transmission speed and power consumption. USB 2.0 is an older standard with relatively slow transmission speed and is suitable for connecting keyboards, mice and other devices that do not require high-speed transmission; USB 3.0 and USB 3.1 are new generation standards with fast transmission speed and good compatibility, and are suitable for Suitable for connecting high-speed transmission devices such as mobile hard drives and cameras.
It is very important to choose the desktop computer host USB interface type according to your own needs. If you just do simple work and browse the web, then the USB 2.0 interface can fully meet the needs. After all, these applications do not have high requirements for transmission speed; but if you need to frequently transfer large amounts of data or connect high-speed devices, then choose USB 3.0 or USB A 3.1 interface would be more appropriate.
In addition to the type of USB interface, the number and location of USB interfaces are also important factors to consider when choosing a desktop computer host. A desktop computer host has enough USB interfaces to facilitate us to connect various external devices and avoid the trouble of frequently changing interfaces; at the same time, the location of the USB interface should also consider the convenience of use. For example, the front USB interface can facilitate us Connect mobile devices, and the rear USB interface can connect fixed devices.
When choosing a desktop computer host USB interface, you also need to pay attention to the USB interface version compatibility. Generally speaking, the higher the USB interface version, the better the compatibility. It can be backward compatible with older version devices and also support new version devices. Therefore, when purchasing, it is best to choose a USB interface version with better compatibility so that there will be no incompatibility when connecting various devices.
The correct choice of desktop computer host USB interface has a great impact on our daily use and work efficiency. I hope that the above introduction can help everyone better understand the importance and importance of choosing a USB interface. method. Ultimately, choosing the appropriate USB interface type, quantity, and version compatibility can make our desktop computers more convenient and efficient to use.
Computer USB interface failure is a common problem. Possible reasons include:
Driver Problem Hardware failure USB interface dust clogged system setting errorFirst, you can check the driver and system settings through the following methods:
In Device Management Check whether the USB driver is working properly in the device. Check the USB settings in the system to ensure that the USB interface is not disabledIf there are no problems with the driver and system settings, then it may be It is a hardware failure that causes the USB interface to malfunction. You can try the following methods to check for hardware failures:

USB 포트는 여전히 타기 쉽지만 걱정하지 마십시오. 다른 하드웨어에는 문제가 없으며 마더보드에도 문제가 없습니다. 일반적으로 마더보드에는 여러 개의 USB 포트가 있으므로 걱정하지 마십시오. 10,000개 이상의 기계가 있으므로 조심해서 사용하세요.
어떤 줄을 바꿔야 할까요?
케이스 전면 USB 인터페이스가 단락되었나요?
그런 다음 케이스를 열고 케이스 전면으로 이어지는 USB 케이블을 뽑으면 됩니다. 마더보드 뒷면의 USB 인터페이스가 단락된 경우 수리해야 합니다. 나는 이런 가능성이 매우 적다고 생각한다.
케이스를 열고 케이스 전면으로 이어지는 빨간색, 흰색, 녹색, 검정색 연결 케이블 2세트를 확인하고 전원을 켜보세요. 전면 USB 인터페이스를 사용하지 마십시오.
뒤에 있는거 이용하세요. 불편하시면 USB 확장포트 1~4개 사서 사용하세요
