    2879 Milk damage

    I found a short on PP1V05_SO, I pulled L7620 and seen it was on pin 2. So I tried some caps above it and pulled U7600. Short still there. So I injected 1.5V into C7660 and see that U1400 gets hot first when freeze sprayed. I can assume u1400 is bad, correct? I did a USC at different angles also...

    3476 Has VCore, no: boot, image, chime etc

    For BIOS I can just pull and put on another, nothing special I have to do? I will try ! Question: so if there was a light on the mouse, then you say its brain dead?

    3476 Has VCore, no: boot, image, chime etc

    With USB mouse attached it will blink the light for 1 second and thats it. In my HP laptop the light stays on. So I am assuming a brain-dead board? And with a PC USB keyboard and shorting cap on and holding Window key, Alt, P, R does nothing. Tried all several times. Pulling the plug on life...

    3476 Has VCore, no: boot, image, chime etc

    ...............I don't have the history, the person it came from doesn't know either. It seems very clean and untouched. Runs nice. I know it is no use measuring everything if have VCore, ALL_SYS_PWGD, & SMC_ONOFF (or is my thinking wrong)? I will get a mouse and keyboard............... [I was...

    Is external keyboard mandatory? & it has to be a USB keyboard and not a wireless keyboard, correct? & I imagine it has to be an Apple keyboard for the option and power button right? LOL

    No water damage, no visible corrosion. Tried PRAM reset with a new keyboard (don't have external), connector looks good. Tried SMC Bypass, Safe Mode, known working drive. Don't have USB mouse, used iPhone w/ammeter and see that it is charging the iPhone 1.5A I think it said. VCore is 1.74V...

    [SOLVED]820-3437 Smoking Joe Frazier Q7560

    No short there or on any pins on Q7560. I did change Q7560, Q7520, Q7130 & ISL. And Q7560 smokes again. (Parts came from a donor/s)

    [SOLVED]820-3437 Smoking Joe Frazier Q7560

    A1466 came in stone dead. No PPBUS_G3H. Resistance to ground was near 0. So I injected 4.0V into G3H and see that Q7560 go hot. Changed it and only got 0.5V on G3H. Found F7140 was no good. Changed it and when I plugged in DC power Q7560 started to smoke. I see Q7560 does go to ground, so it is...

    820-3437 smc_lid = 0.5v

    Once I confirm the issue, I'll go fishing for a good SMC.

    820-3437 smc_lid = 0.5v

    The original one wasn't working I was supposing. I have a known good working SMC that I am going to try (waiting on stencil from Rossmann).

    820-3437 smc_lid = 0.5v

    Think it is most prudent to take a known working SMC out of working MacBook to test. Will try this, then order another chip. That will narrow down the variables.

    820-3437 smc_lid = 0.5v

    Where can we get some good ones at? Where you at the iFixit thing?

    820-3437 smc_lid = 0.5v

    So maybe just keep trying different SMC's?

    & I didn't see any corrosion under the chip.

    Kenny Rogers - know when to hold them & know when to fold them. So I guess it is wise I give up. LOL.

    820-3437 smc_lid = 0.5v

    Ha, ha. LOL. OK. Not brand new. But purchased one for $15 and installed it. It has the same results.
