HP Power adapter problems?

I have a HP Smart AC/Auto/Air Combo Adapter, and today it began to fail. To get it to work I have to shake the adapter itself mulitple times, and then it starts to work, and works without a problem. It has only begun to do this occasionally, but it is getting really annoying. Does anyone know what could be wrong with it? Thanks!

You have possibly:

1. A broken wire into or our of the PSU - try next time it fails carefully bending each wire along it's length bit by bit.

2. A broken PCB inside the case.

3. A bad soldered joint inside the case.
