It didn't work. It still doesn't charge the battery. I checked all the resistors near the CD3215, and I didn't find anything wrong. Any other tips?

I've never done this procedure. I need to look for the socket for this chip. Does the ROM have any specific files for this model?

Yes, I checked all the LDOs of the CD3215, diode mode and voltage, everything OK.

It seems the problem has been solved. Sound has been working for a few days now.

No history. The board is very well preserved, without oxidation or liquid marks. Sorry! Yes, it was the 3V3_G3H_RTC line. After a while without use, the board showed 0.380 when measured in diode mode, but when I put the charger in and took it out, it went to 0.120, 0.140! I injected 3.3v, the...

The device turns on normally with the battery charged, but the Mac does not recognize the charger in any port. With the battery, I have 20v 0a. Without the battery, the Mac does not turn on, I have 5.13v 0.23a. I have 12v on the PPBus. In the CD3215 tests I noticed that at times I have, in...

I waited for the sound problem to appear and compared pins 16/18/20 with another board! In diode mode, pin 20 was giving 0.120, while on the good board it was 1.700. I replaced C6602 and L6607, now it's the same and the sound is working. I'll keep testing to see if the sound fails again. I'll...

Imac with intermittent sound. Sometimes the sound comes out of the speakers normally and then switches to the optical output. The volume icon shows a prohibition sign. I tried changing the P2 connector 3 times, but the problem persists. I searched the forum for alternatives to "kill" the P2...

"So it stays on in boot menu?" Yes, it gets stuck in the Menu. It allows you to choose the boot option, but when I select it and press enter, it gets stuck with the boot options and doesn't even start loading. "It only crashes when try to boot OS, or ASD?" When I turn it on without the battery...

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
