This is something I think everyone has done, when your TV, AC any remote stops working and once you hit it few times against any hard surface that remote miraculously comes to life for atleast few chances. How does that happen?
In: Technology
What’s going on is that, while the batteries in the device are discharging, a thin film of corrosion builds up on the terminals and impairs the connection to the device. Banging the remote against the wall slightly shifts the batteries, breaking the film and restoring connectivity.
