Recent problem: the connection is loose to the magsafe power port, it’s difficult to get it to charge unless I push and wiggle it till it seems seated, it stays for a few secs, but then releases itself and the connection is not good enough for recharge. I’ve managed to get it to stay after several attempts, but the problem will only get worse so want to get it sorted before it won’t charge at all. Incidentally the magnetic plug is very hot too. Can I replace the magsafe power port easily?
