I had a client once called me and say I know you only do computers, but I have this issue with my cell phone. It would not charge even after multiple cable cables. He said he went to four different cellular stores through all their tech-support peops. I turned it over, looked in the charging hole. It looked, kind of not deep. I got a paper clip, popped out a lump of dust like belly button lint. Charger worked just ducky after that.

In support it’s usually not the complicated solution.
