Single work

820-00165, Dead


This board looks dead. When I connect the magsafe it has no green light and no power.
Tried starting the board from the battery and shorting r5116 to ground. Board starts normally. My problem is that it wouldn’t run from the charger.
So my analisis will be focused on pages 49 and 50 of the squematic.
Have 0v on pin3 of J7000, charger connector. Got pulsating voltage on pins 12, ppdc_in.
No shorts on l7095.
D7005 gets 0v on all three pins. However with battery only it gets the 8v pins 1 and 3. No shorts on pin2.
Getting 0v on pins 4 and 5 of q7010.
Ok, found my problem on pin2 (K) of D7011. It was reading open, when It should be around 0.700. After replacing it now board is starting from the charger and working normally.
Board fixed.
