Hello all. I would like to start this new thread to see if we can make it easier to keep track. Dadioh had started a thread that has been going on for a long time and has some awesome info in it on fixing your MacBook Pro. My current issue is a 2009 with no power. Magsafe does not light up at all G3Hot is 1.15v instead of 3.42v. I am currently checking the PBUS SUPPLY/BATTERY CHARGER circuit . With no battery installed and magsafe only: Q7000 and Q7001 get a fluctuating 16.4v-16.8v and appear to be operating correctly, just not getting steady voltage. Q7020 is where the problem seems to be. It has 16.4v on pin 5, .09v pins 1-4 which is wrong. So my question is: Do I have a bad Q7020 or is the IC chip bad sense I am getting pulsing voltage through the other points mentioned?
