Yes, without a trackpad the battery is recognized, charged and the Mac works only with it.

It was the first thing I tried (I forgot to comment)! I also tried with a good bios chip! Nothing changed!

SMC_LID with battery and trackpad connected is 3.4v, stable

Yes, both crash as soon as the apple appears. Just to be sure, I put this board in a complete topcase (keyboard, trackpad, battery), working 100%. Same problem.

I was able to run ASD 162 without the battery connected! With the battery on, when I choose to boot from ASD, the Mac crashes. It only showed an error in the battery sensors. Probably because it is without the battery. Sensor - Temperature (TBOT) -- Battery TS MAX (test 1) Sensor - Temperature...

Yes, the trackpad works normally without the battery. I tried to run it in diagnostic mode, but it doesn't work, it shows Apple support website and -510d. This model no longer has ASD, right?

I found some oxidation near J5250 and U7310. But nothing causing a short circuit. I replaced the components and cleaned everything. But the problem persists. The owner of the Mac did not report any previous problems.

I'm struggling with this logic board. If I turn it on with the battery and trackpad connected, the system doesn't start. If I disconnect the trackpad or the battery, it starts normally. I tested it with another battery and another trackpad, same problem. I checked the resistors on the trackpad...

R1212 is OK! PM_BATLOW_L in diode mode - 0.560

Yes, I tried up to 96w!

With the 100k resistor, I have 2.8v at PCH_INTRUDER_L. But it's still dead. and PM_BATLOW_L - 0.7v

Some measurements are not good! =/ PM_DSW_PWRGD - 3.4v PM_BATLOW_L - 0.7v PCH_INTRUDER_L - 1.4v PCH_SRTCRST_L - 3v RTC_RESET_L - 3v

I tested PM_PWRBTN_L when I activate SMC_ONOFF_L, it pulses to 0.3v. But I have no pulse in PM_SLP_S4_L, it is always at zero. Not a good sign, right?

I agree that the PPBus with 12.5v is perfect. But as I mentioned the Q7030/40 and when I checked it I noticed a difference, I found it strange. Any other suggestions?

Something changed in the Q7040, pin 12 in diode mode had 0.830, I found it strange that now it has 0.480, then I discovered that they are shorting with pins 11 and 10. I will order the components to change.

Yes! I also get the PP5v_S5

Do you suggest any other tests?

PPBUS_G3H is 12.6v

Sorry! There are so many measurements that I got confused in the description. On the C7050 I have 12.6v. I checked the AUX_DET again, I have 4v. I may have gotten confused. I checked the Q7030/40 in diode mode, on each pin, I found no changes.

The logic board is perfect, no oxidation. Using the original 96w charger, I have 20v - 0a on the 4 ports without the battery. With the battery connected, it gets 20a - 3a, but it doesn't turn on (probably charging the battery). I checked all the CD3215s (even with 20v, I thought it was better...
