Dell Laptop Usb Ports Not Working. HDMI port seems to have stopped working on laptop. Check if your USB device is functioning properly.
Updated BIOS and all other updates and they started working again for a day. If this doesnt work physically check the USB ports with a strong light and a magnifying glass to see if all the pins are straight and parallel with each other and that they are all there should be 4 pins per port and that the port is clean and has not got any. This video shows you how to fix USB ports on laptops and PCs.
Run dell diagnostics to check for hardware issues.
If I recall there is a bios setting to allow all Dell thunderbolt docks. Check if the ports are not physically damaged. Plug the power cord or AC adapter. Hi Try uninstalling all the USB universal Host and Enhanced Host if any controllers in Device Manager and restarting the laptop.
