2informaticos replied to the thread A2485 MacBook Pro / 820-02100-A board / 5v .11a / Logic board failure /.Short to ground. Use voltage injection method to find the culprit. As always, start with just 1V; set amp limit to max first.

2informaticos replied to the thread Macbook A1706 820-00239.Very likely. Just in case, inject voltage there; no more than 1.2V anyway. Remove CPU heatsink first.

2informaticos replied to the thread A2779 (820-02841-05) Keyboard and Trackpad Not Recognized After Replacement.You probably have a problem with TP only. KB can't work alone. So check first all JT400's power rails.
