USB port or device not working

Work out what's faulty

1. Try another port on the computer.
2. Try another device in the same port, such as a USB stick or mouse.
3. Try another cable, especially for phones and USB-C devices.
4. Plug straight into the computer, not a hub or dock.

If other devices work in the port, the problem is the device or cable. If nothing works in one port, the port may be faulty.

Fixes

• Restart the computer, not just shut down.
• Reset the USB drivers: in Device Manager, expand Universal Serial Bus controllers, right-click each USB Root Hub and select Uninstall device, then restart.
• Stop power saving: search for Edit power plan > Change advanced power settings. Under USB settings, set USB selective suspend setting to Disabled.
• Check for dust or debris in the port with a torch, and clear it with compressed air.
• External hard drives may need more power than one port supplies. Use a powered hub or the drive's own power adapter.

USB-C ports aren't all the same. Some only transfer data, while others also charge or connect a monitor. Look for the lightning bolt (charging), DisplayPort or Thunderbolt symbols next to the port.

Port loose, or only works at an angle? This is a hardware fault. Contact us
