Checked, the USB indicator doesn't blink. It stays always on.

That's sad :( But anyways, thanks for your support.

Can we replace the SSD?

Did I cause this? What should be done now? I mean, is SSD replacement a viable option?. In my experience SSD short on this model is becoming one of the most common issues. I searched on YouTube, didn't find any videos on this.

After the bypass, the device doesn't work. Only the USB is active. SMC sensor switch looks clean. PP3V3_S4SW_SNS is 3.3v and goes up and down with the rest. What next?

Received condition: Tea spill, damage near the NAND area. The Voltage was stuck at 5v. After the cleanup: - Cleaned the whole area. There was a lot of crap underneath the U9080, so removed it. 2 pins were gone. - Connected power, 5V and 200mA, the C9080 was heating. Heard a crack, removed...

Yes, the MLB doesn't go off after the SMC Bypass. Without SMC bypass it keeps restarting.

J6100 - absolutely clean. SPI Bus Termination resistors - Values are fine PLT_RESET_L - Fluctuating between 3.36 and 0.09

I am sorry, you need to guide me a little more. I am new to this. What information do you need?

With a donor SMC, the device is back to almost the initial stage. Fan spinning continuously but the current drawn keeps cycling between 2mA - 405mA. What should I check next?

I installed the same SMC after reball, didn't work. Installed a new SMC didn't work. Does SMC need any kind of programming? Should I use one from a donor board?

Tried with SMC bypass, still same

I don't know if it is silly to ask, but how perform SMC bypass?

The only visible damage on the MLB was near the TPS. Fixed it, but the device doesn't boot when the battery is connected. Once you disconnect the battery, it works fine. Also, tested with a new battery, no go. No idea where to start from, please help me.

Thanks @2informaticos. Does the symptoms indicate SMC issue? There was not much corrosion near SMC. Checked from all sides under microscope looks clean. I just reflowed it.

Hi @dukefawks, I also need help with the same issue on 820-3662 MLB. Any development on this?

There was a corroded capacitor C1902 near the U1900, replaced. 2 registers near SMC replaced No sign of any other visible damage. Stage 1: The fan is spinning and it shows 430mA on the power supply. All voltages are present and the CPU is also getting warm. Stage 2: It goes off and comes to...
