    820-2915-B - Green light no boot (no 5V)

    I've been in denial thinking that the SMC was shot... *sigh*... on to the next one. Thank you for your help.

    No boot and no Green light. One wire has 3.42v at u6900 pins 1,4 and 5 u6900 has 3.42v at pins 1,2,4 and 5. 3.42v at pin 14 u7000 so I have SMC BC ACOK.

    No doubt. I'll start over and see what I can find. I did find a bad R7261 pin side was broken off. weird. I'm not sure if that was an original problem or the result of my shorting out the other resisters. I measured at those resistors because they were ones that show up when searching for...

    PPBUS_G3H "was" stable at 12.6v until I shorted r5301 pin 1 and R5312 pin 1,, now the 12.6v is dropping slowly... no green light any more... $##%!^&#@^.... Previous to my shorting the to resistors.. I had 0v at PP5V_S3.

    Yes. at u4900 pin 119 3.3v-.099 R7941 3.2v-.007

    yes at R7941 3.3v - .007v at R7940 3.3v-,014v at U4900 pin 119 3.3v-,014v

    PP3V3_S5 is pulsing but much less voltage: r7940 1.002v - .002v R7812 .998v - .003v BTW thank you for your help. I'm sure that much of this is a pain in the *ss for you but the assistance you offer is very much appreciated.

    So following G2_EN. At R7940 the voltage fluctuates from 3.4v to .003v rapidly.

    Checking it at u4500 pin 3 It reads .088 which I guess is nothing. c4501 the same .087 u4350 the same .087 c4350 also only .087

    Q4260 pin 4 is 12.57v and pin 3 is 12.24v

    Interesting R4260 and C4260 have 12.59v so does Q4262 pin 4 4260 in 1,2,5,6 have .03v each. F4260 is also .034 both sides.

    5V_S3 at l3408 0v R4532 0v U4600 pin 5 0v 3V3_S5 C4605 0v C9841 pin 1 Fluctuates from 1.01-.0046 U9480 Pin 5 Fluctuates from 1.01-.0046 SMC_ADAPTER_EN u4900 pin 64 3.3v R5074 3.4v

    Yes to the know good 85W OEM charger. PPBUS_G3H at R5400 and R5410 is 12.59V F7040 and F7041 12.59v

    This board looked very clean. There was corrosion on J3500 pin 16 but no where else. I used the USC anyway but I couldn't see any other issues. I'm not sure where to find the course of the PP5V_S0 but after looking and looking It seems to come from U9500. There is no 5v coming from here. No...
