If you’re trying to charge through a port designated for data transfer only, switching to a dedicated charging port should resolve the problem.

3.    Switch USB cables

Before taking more extreme measures, swap in a brand new USB cable if you have an extra one. Cables can wear out or get damaged over time. If a new cable fixes your connectivity problem, then you know the old cable was faulty and needed to be replaced. Always good to rule out easy fixes first!

4.    Clean Out Debris

Take a close look at your USB ports. Food crumbs or dirt can get stuck in there and stop your device from connecting properly. If your cable doesn’t plug all the way in, something is probably blocked. Use a flashlight to peek into the port and see if you spot any gunk. If you do, turn off your computer first. Then, carefully use a toothpick to loosen the debris so it comes out. Canned air can work too to blow out any dust bunnies. Just don’t stick the nozzle down into the port, or you might cause water damage. If your device connects only when you wiggle the cable, the port itself is likely bent. You’ll need to open up the computer case and see if you can fix it or take it somewhere to get professional help.

5.    Restart and Update

Sometimes a USB port stops working properly because of a small computer error. Restarting your computer can fix these kinds of issues. On a Windows computer, click the Start menu, select the Power button, then click Restart. On a Mac, click the Apple menu and select Restart.

Updating your computer’s software can also help get a USB port working again. Software updates include improved drivers – the programs that let all your devices connect.
