Ultrasonic the board. 1 gallon distilled water, 103 milliliters branson EC. then off to a small tray of 99% alcohol, then into an air filter or fan to dry for ten minutes, then to an oven for 225f for 30 minutes. NOT TO MELT SOLDER, that is bullshit and never fixes anything, but just 225f to get rid of the alcohol/water residue hiding. Then it will work again. No more contact cleaner, that is not for laptops.
