Why do some computer USB interfaces have no power? What can I do?

Causes and solutions for why the motherboard USB does not provide power:

1. Check whether the USB data cable and USB interface are normal.

2. Whether the system is damaged and whether the driver exists. If there is no USB driver, it is recommended to reinstall the driver.

3. Plug in the USB device, turn on my computer, refresh it several times and see.

4. Check the main board settings. Check to see if the USB port is open. You can modify it by pressing del on boot. Start the computer, enter the motherboard BIOS settings (press the del key on a desktop, press the F2 key on a laptop), check whether the USB related options in the BIOS are turned on:

1. PNP/PCI CONFIGURATION (Plug and Play device and PCI configuration settings) is used to set interrupts and other differences for ISA and other Plug and Play devices

2. BOnChip USB is set to Enabled;

3. USB Controller is set to Enabled;

4. PNP OS Installed is set to Yes;

Secondly:

The reason for this problem: It is because the USB interface has After making a battery protection circuit, if the current of your device exceeds the maximum USB current, the computer will automatically shut down your device.

Suggestion: Power the USB device separately, or buy a PCI to USB card and connect several of them to the USB adapter card to solve the problem.

Solution to the insufficient USB power supply of the additional motherboard:

There are many reasons for the insufficient USB power supply of the motherboard. Many low-priced mid-to-low-end motherboards have made trade-offs in the motherboard materials, resulting in USB power supply can only drive some devices with relatively low power consumption. There is no good solution for this kind of situation. For example, a 2.5-inch mobile hard disk can use an independent external power supply, or a dual USB interface can use two Use a data cable powered by a USB interface to solve this problem. A problem similar to yours may be that the extension cable is too long, which causes a lot of power consumption on the cable. The solution is to replace it with a better material and a higher impedance. Low cables, or don’t use extension cables that are too long. The cables designed by USB legends are not that long. If they are too long, they will cause transmission interference, data transmission errors or be very slow.

The usb interface is out of power?

USB is out of power, the reasons are as follows:

1. The front USB cable is connected incorrectly. This type of fault will occur when the USB cable on the motherboard is connected to the front USB port on the chassis and the positive and negative connections are reversed. This is also very dangerous, because the reverse connection may cause the USB device to burn. ​

2. The voltage of the USB interface is insufficient. ​

3. Compatibility issues between motherboard and system.　

4. System or BIOS problem. USB device not recognized in the system happens when USB is disabled in BIOS or operating system. The solution is to enable options related to USB devices. Just turn on the computer and press the F2 or DEL key to enter the BIOS and select enable usb device.

The computer has no power when the data cable is plugged in?

1. The USB plug of the data cable is not in good contact with the USB on the computer. The reason is that the fit is not good or the USB interface on the computer is loose. You can try another one;

2. Possibly The problem is that the USB socket on the computer has insufficient power supply capacity. For some thinner and lighter laptops, the output current of the USB socket is too small, which may cause the problem of being unable to charge (but this is rare). It is recommended to try another USB interface;

3. Sometimes, when the data is connected to the computer, for some reason, the USB socket is momentarily short-circuited, and the USB port is protected from power overload. Just restart the computer;

4. The USB socket on the computer is disabled. After entering CMOS, change the option to make it valid;

5. The USB socket on the computer is broken or the USB control circuit is damaged, causing the USB interface There is no current output, so you can use a USB socket.

The Weilang usb connector is out of power?

If the USB port is not powered on, there may be a problem with the USB cable or the charging module. Try connecting the USB cable to the computer. If it is normal, the charging module is damaged. If there is no response, find another USB cable. If it still doesn't work, it's a machine or battery problem. The USB interfaces in the car are set up for audio data transmission. Their main function is to plug in U disks and play music. Therefore, the interface current of most vehicles is only 0.5A. The rated current for mobile phone charging is 1A. Long-term charging will cause If adverse reactions occur, it is recommended that car owners reduce charging usage to play a certain protective role.

Why is there no power in the USB and HDMI interfaces of the host computer?

1. Check whether the USB data cable and USB interface are normal.

　2. Whether the system is damaged and whether the driver exists. If there is no USB driver, it is recommended to reinstall the driver.

　3. Plug in the USB device, turn on the computer, refresh it several times and see.

　4. Check the main board settings to see if the USB port is open. I suggest you check it on the website, consult a professional, or read a book.
