I’ve got a laptop with 2 USB Ports, but one only works at a certain angle. Works fine when pressure is constantly applied, no rotation. Works when tilted down (from upper view). Works when USB is between plugged in & unplugged. Sometimes my mouse lights up, but it doesn’t work.

I have one that is intermittent also. I think it is the contacts inside the socket. They are a spring hump design. If you are careful, you may be able to lift them using a fine tweezer. They won’t need to come up much. Get the tweezer point just under the hump and lift it slightly. Do all 4.
