I have replaced L3700 and the SSD connector. Still no improvement. 😭😭😭

I have replaced U3710 and U3711. Unfotunately no improvement. The SSD connector looks good to me:

Okay, I will try. I've just made these two pictures with a thermal cam. It is the same SSD in both pictures. One in a working 13" 2015 MBP, the other one on that faulty 13" 2013 board.

Yes. I am using it right now. And I have tested with another known good SSD which also gets burning hot on that particular board.

I had these readings when the SSD was hot. I could connect a display to check if it gets recognized or not and repeat the readings. But I think the temperature already indicates that something is very wrong. It gets not only warm, it gets really burning hot.

The board had traces of water damage at C8357. I have replaced it and have rebuilt contact to both sides of the board. Pad 2 of C8357 (which goes to the display connector on the other side) was gone. But now I have continuity where it is supposed to be. Besides that, there were no other traces...

Thank you, I will try this. It also runs slow after the OS booted up. No, sorry that was misunderstandable. I mean the Big Samsung chip that is soldered on the original Samsung SSD. The same chip gets hot on a 100% known good SSD. While the same SSD does not get hot in a working macbook. I...

Same problem with a known good SSD. The big Samsung Chip close to the connector of the SSD gets very hot. On the screen there is a questionmark folder. In like 1 of 10 tries the SSD gets recognized and the OS boots, but it operates very slow.

Unfortunately it is only partially fixed. Sometimes it recognizes the internal SSD, sometimes not. I noticed that when the SSD is not recognized, the SSD gets burning hot.

While waiting for your answer I have removed Q8150, to see if that's what's causing the problem. Then I measured ALL_SYS_PWRGD without Q8150 and the fan still stopped spinning. So I soldered Q8150 back. When I reconnected the board to do further measurements I noticed that the CPU got hot! I...

PM_SLP_S3_BUF_L is constantly 3.35V, all U8180 voltages are 3.35V (except GND of course) and R8167 is exactly 10 K Ohm.

I have a 820-3476-A with fanspin but the CPU remains cool. When I try to measure ALL_SYS_PWRGD the fan instantly stopps spinning and the multimeter shows 0V. When I disconnect the power cable and reconnect it, the fan spins again. But when I measure the resistors R8169, R8165 or R8168 at their...

Hello I have a Battery "Service recommended" warning on a 16" 2019 MacBook Pro (A2141) in Big Sur. The Battery has 290 cycles. Coconut Battery shows the manufacture date 1979-11-30. I have upgraded to Monterey and there is the same issue. Then I've downgraded to Catalina and everything is...

The problem is, that I have no clue what to do with that .bin file that you have sent.

I've found the youtube tutorial "How to clean ME region on Apple machines" by piernov. I used Linux like in the video. But I only get to the point where I have to open ME Analyzer. It gives me an error message (screenshot in attachment). Then I've tried opening ME Analyzer on a Samsung Laptop...

@ 2informaticos: I do not own a Medusa and right now it is too expensive for me. I have searched the net for a couple of hours today on how to do it without a Medusa, but I have only found tutorials that don't work for me. Can you recommend me which is the best method to do it when you don't...

A couple of days ago I've already swapped the Bios chip (U6100) from the second board to the first one with no improvement. The scond board had no such symptoms before the Ram failed. After the swap, the first board is still slow. Would it still make sense to clean the ME region? Is it located...

I have run the EFI ASD and the OS ASD. Both passed. Yes, the problem in normal use is that the machine is very slow. It is useable but every task feels slow. Installing an OS takes forever. Any further idea? Is it possible that the CPU itself is partially faulty? I have another 820-3023-A...

Thank you! :) I have done multiple PRAM Resets. High Sierra from an external HDD has the same issue. Geekbench 5 score: 149 single-core / 387 multi-core. I have read that I need ASD 3S146 for this MacBook. I will get it from macintoshrepository.org and post the results. The download takes a lot...

The Geekbench score of this MacBook Air is very low, so I have checked clock speeds with HWMonitor / Fake SMC. It runs at a maximum of 800 MHz instead of 1.7 GHz. Another symptom is that the SSD write speed is low and it fluctuates. There is no liquid damage visible. I have checked the four...
