Hello;
I ve got a macbook pro model A1502 with board number 820-3536-A with a the problem that the battery does not charge till 100%. After 40% it stops charging.
The laptop stays on my shop for a while waiting for the battery from china that after waiting 5 weeks it seems that the supplier didn t send it. Then I ve ordered the second one. After waiting alomost 3 months on the battery shows up, I ve placed it, but on my surprise the laptop did not want to start. After the first check I ve noticed that Q7010 got PPDCIN_G3H at the source but no voltage is passed to the Drain. The reason was because the Gate has a high voltage. After looking well I ve seen that the DIODE D7010 was absent. Maybe a nail s work.
Next problems shows up, because I didnot had such diode. I ve used a resistor there instead of a diode just to be able to troubleshoot verder. I ve loweradge the voltage at the gate to let the Q7010 pass the voltage the drain.
Now first problem was solved, but the problem is still the same. Mac does not want to boot.
I ve checked some coils to ground, like L7130 and L7520 and they give short to ground. The next check shows up that the U7700 does not looks well like if it was explodes. I ve lifted it but the short still on both coils.
Any hind is welcome.
