AC Adapter Repair
My AC adapter for my laptop had died, but having an electrical engineer for a dad, I wasn't about to blow 50 bucks on a new one with seeing what could be done to repair this one.
The first thing we did was cut it open, and we made a startling discovery.
They just modified a universal AC adapter with thier plug and put some plastic around it to conceal this cheap design. It's also why it broke so easily. Those pins were soldered where the cord took a lot of lateral force and solder isn't made to take direct force and is very weak so it broke.
So we decided to resolder the joints and see how long that lasted. Make sure you know which pin you solder to the tip point because you have to make it tip positive (which the pin-holes are marked pos and neg).
There's our repaired AC plug which we just inserted into the pin holes.
But it broke too. So we went to radio shack and discovered a C-sized AC plug would find the laptop and plug into the existing adapter.
