circuit board. If the surface of the pad becomes corroded, the rubber can no longer conduct electricity from one side to the other. If you can get the computer apart without destroying it (look for screws on the underside), and get it back together, then scoring the copper pad with a ...
Circuit board fixes: On equipment without external shields; the next option is to work with the circuit boards. Handheld radios and sniffers, H-field, E-field, and high-impedance scope probes all help localize the issue to identify it better. Depending on the exact problem, you'll need to...
Multi-Circuits: While debugging, there will be two different colored sets corresponding to signal sources and endpoints. When all signal sources have been connected to the endpoints of the corresponding color, then this circuit debugging will be judged successful.Unsolved MotherboardSolution...
