The purpose of this article is to share with you what to do if the laptop usb interface does not respond. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. Caused by improper human operation

The failure to respond to the notebook usb interface may be caused by improper human operation. The reason may be that the system was using USB when shutting down and unplugging the USB cable, that is, the system has already disconnected the USB without realizing it, or it may be that the laptop is shut down too quickly and forcibly shut down the WINDOWS without waiting for some programs or services to shut down. This may cause the situation that the USB will not be recognized the next time you boot (more than one port, all may not work), and the reinstalled driver may not be recognized either, but the Windows7 system has the automatic repair feature in general, and the problem will be solved by rebooting once.

The 2.BIOS setting disables the USB feature

One of the BIOS settings on the computer motherboard is to set the USB switch, and the default value of this option is on, but if you are not careful or if the BIOS setting is wrong, it may also cause the USB interface to be disabled. You can check whether the BIOS setting disables USB. You can restart the computer, hold down the DEL keyboard on the keyboard, then enter the BIOS settings, find the USB settings item in the interface, and check to see if it is disabled. As the BIOS settings are all in English, you can look it up directly on the Internet if you don't need it.

3.USB connector damage or motherboard failure

The USB interface is mainly on the motherboard of the computer. If there is a problem with the USB interface on the motherboard or there is a failure on the motherboard, then the USB interface cannot be used. If the problem is really the motherboard, then the problem that the USB interface cannot be used can only be solved by repairing or replacing the motherboard.

4. USB service is disabled by the system

This will not happen if this service is not set up, but there is also a special case, that is, many people have some optimized antivirus software installed on their computers, so when using these software, you can disable the USB service. At this time, you only need to unban the USB service. Open the antivirus software installed on the computer and check whether the "system plug and play service" is disabled. If it is disabled, it may cause the USB interface on the computer to be disabled. At this time, we can turn on the "enable optimization service" in the antivirus software, and then unblock the "system plug and play service".
