Stop your laptop cable from falling out

The charging connection for our old laptop has become very slack over time, and constantly falls out of the back of the laptop. Using Sugru, I created a squared-off platform at the top of the connection, just before the part that goes in to the socket, to which I attached a piece of Velcro with a hole punched in it. The other side of the Velcro was attached around the charging socket of the laptop.
