I forced it into DFU mode using the jumper method. No DFU mode. Voltages present in the coils. I compared it with another board that works.

Using original 96W charger Does not enter DFU No history. PPBUS_G3H - 12.63V PP3v3_G3H_RTC - 3.38V PP3V3_G3H - 3.38V PP1V8_SLP2R - 1.79V PP1V1_SLPS2R - 1.1V PP0V8SLPS2R - 0.79V PPVDDCPUSRAM_AWAKE - present 0.8V PPVDDCPU_AWAKE- present 0.53V PP1V2_AWAKE - present 1.2V present...

Without the F7000/1 fuse, it's 12.3V. With the fuse it's 4.8V. PP3V3_G3H_RTC_X 28mV | diode mode 0.390v I'm using the original 96W charger.

Hello, I have this mac that was working, but stopped turning on unexpectedly. There was no contact with liquid. It replaces the U7000, Q7030/40. C7030, R7030/40 are okay. Voltage: I removed F7000/01, in the PPVBAT_G3H_CHGR_REG mesh there is 12.33V. In diode mode on the PPbus 0.275v

Hello, I have this mac that does not turn on. According to the customer, it was connected to the charger and did not turn on after a lightning strike. There is no sign of burned on the board, but I identified that it has already passed through another workshop. A CD3215 was replaced (U3100), CPU...

Yes, only when I select the "Revive device" option, and the loading bar gets stuck at the end, along with the error message on the other mac.

Hi, I have this mac that won't turn on, however it has all the SSD voltages and the trackpad clicks. When I put the mac in DFU mode and select the "Revive device" option, I get a "Missing data volume" message. The customer authorized the "Restore" option, and although the mac displays the apple...

It was a BIOS problem, thanks for the help. It was a bit tricky to find a working version, I had to transplant the ME region of the client BIOS to a new BIOS version. I will provide the final version below.

I removed the battery, same behavior. No history from the client. L7650: 5V L7610: 3.3V L9900: 1.35V L9810: 0.8V L9820: 0.8V L9740: 0.8V L7310: 1.1V (should drop below 1V?) L7930: 0.9V L7810: 1V L7150: 1V L7130: 1V L7110: 1V L7230: 0V L7210: 0V L8100: starts at 10V and drops slowly to 0V every...

Hello, I have this board that is not turning on. The first LED is stable, the second one turns on for about 10 seconds and goes off. After about 3-4 seconds, the second LED turns on again, but this time it stays on. I honestly don't know if this is the standard switching behavior of this board...

C9101 was missing

Good afternoon this mac I can not format the SSD, already tried good Bios, but without success.
