I checked and tested, nothing! Any other tips?

Yes, without the battery, it has 5v pulling 0.25a, on all ports.

I placed the logic board in a topcase with a good battery, it turns on, but does not charge the battery. It pulls 20v, but pulls 0.002a. The DFU restore attempt did not erase the Mac. So the system starts normally. U7000 Basic Voltages P_IN - 5.2v AUX_DET - 1v SMC_RST_IN - 0 VDDA - 5v VDDP -...

I did the DFU with the Mac battery. I'll try with another battery. Is it possible to enter DFU with the logic board outside the topcase?

I always get this model board with this problem. It had oxidation near UB300, with a short on the PP3V3_UPC_TA_LDO (CB308) line. I ended up with the short and the UB300 pulled 5v - 0a, the others 5v - 0.25a. So I replaced the UB300, now all ports pull 5v - 0.25a. Voltages and measurements in...

The child was born!!! =D I changed the U7000, the C7050 went to 12.2v. I put the F7000/1 back in, the board turned on and is charging the battery.

Without the F7000/1, the C7050 has 1.3v L6960 diode mode - 0.430

Now I have some voltages that before, with 20v, I didn't have. P_IN - 5.2v AUX_DET - 1v SMC_RST_IN - 0 VDDA - 5v VDDP - 5v EN_MVR - 0 AUX_OK - he is an NC, is that right? AMON - 0 BMON - 0

diode mode, 3V3_G3H_RTC - 0.440

Sorry, I haven't checked yet. But CD3215 have changed. Do I test the U7000 even with them strange? I checked the LDO lines in diode mode and all four are OK. But the voltages are strange. I no longer have any of the 1.1v LDO line (with charger in the port for the CD3215). The 1.8v line only...

I had 20v, no battery. but during testing, it changed. Now I only have 5.2v and 0a. PPBus dropped to 1v. I was checking the voltages and disconnected the source, when I connected it again, it was pulling 5.2v. What I managed to measure until I lost 20v. P_IN - 20v AUX_DET - 0 SMC_RST_IN - 0...

Did not work. I mounted the logic board on another Mac, it turns on with a charged battery, but it doesn't charge. The board doesn't turn on by itself!

Sorry, but I hadn't noticed. but it fluctuates between 0.03 and 0.08. I have PPBUS_G3H (12.3v) and 3V3_G3H (3.3v) together. Yes, all USB-C ports the same. C7020 - 4.7ohms C7023 - 4 ohms

I've already tested it with others and the direct charger. Same problem.

yes, always with original charger! the 87w one!

Only the board on the charger doesn't turn on. It is at 20v 0.08a. The board with a charged battery turns on. When I connect the charger, it stays at 20v, goes 4a for 1 second and drops again. I checked all CD3215s and they are OK. In all of them I have the 1.1, 1.8 and 3.3v line. Just the...

Board still working. But, WiFi stopped. I found that PP3V3_G3S_WLAN shorted (diode mode 0.008). When I put it on the charger, the U3730 gets very hot. Is it worth changing?

I changed what you suggested and put in new chips (C3215). Board turned on again. Anything to pay attention to in testing?

Yes, original charger. It stayed on charge for around 1 hour. Then I turned it off, took out the charger. Today I went back to test, everything had toasted. The board is perfect. no oxidation. Do I put the new chips in and test?

I ended up removing them all. On each chip, the 3V3_UPC line was shorted, when removing the chip, the short ended. I didn't say it, but the U3100 was causing a short on the PP3V3_G3H_RTC line. Since I already made the mistake of removing them all, any tips?
