Clean out your computer ports with this common household item.
I use my computer a lot in my workshop. Once, the magnetic charging port collected a bunch of metal filings. I tried blowing them out with compressed air, but that didn’t work, as the filings were small and the magnet wouldn’t let go of them. What finally did the trick was sticking a bit of poster putty in the port. The putty doesn’t clog the port and successfully removes anything that might interfere with the connection. — Travis Larson
