Recently both my laptops and my cell phone started to have loose connections where you plug in the charger. I’ve been pretty careful with the laptops and they haven’t been dropped or hard hard use. The big laptop never leaves the house and rarely leaves my desk. The phone? It has been dropped a few times but probably not any more than anyone else’s phone. One electronic with a connection problem is annoying; two may be a coincidence; but three at the same time?
