Reasons Behind Your Laptop USB Port Is Not Working
There are several reasons that your Laptop’s USB Port not working as it used to be. Some of the reasons are:
1. Previously Connected Device
Some of the reasons for the USB port not working properly is to have to do with the device that was previously attached to the port. According to Microsoft, USB ports may stop working when you attach a malfunctioning item to the computer, even after you unplug it. Close the computer and restart it to fix the problem. Another issue is that often connecting and disconnecting an item can cause the USB port to malfunction. Reconnecting the device and checking for hardware changes, rebooting the system, or resetting the USB controller may resolve this issue and restore functionality to the ports.
2. Software Configuration
Invalid software and operating system settings are also common causes of USB port not working. If you have added a new port or device, installed a new operating system, or made other significant modifications to the computer, the problem could be caused by these settings. Changes to the Control Panel, Device Manager, or the main setup application may be required. It’s also possible that the USB port, device, or controller still needs drivers. Additionally, the computer could be infected with a virus that prevents particular accessories or ports from working properly.
3. Hardware Problems
Although software and accessory difficulties are more likely to cause computer issues than genuine hardware failure, they cannot be ruled out. If the computer has a USB card in one of the expansion slots, the card may have become loose or the slot may have failed. A wire connecting the USB port to the motherboard could be broken. Damage to the ports or a failed USB controller is two more possible hardware culprits. It’s also conceivable that the ports are just dirty.
4. Other Problems
If you use the wrong type of USB extension cable, the ports may stop working. According to Microsoft, this occurs when a high-speed item is used with a low-speed USB cable. Because certain older operating systems do not support USB, the ports will only provide power to an accessory. Refer to the computer, accessory, and any add-on USB hardware instruction manuals for more possible causes.
