ok, I get it. Do you have such a board for sale? So I can take parts from there?

I did not understand a bit what ITS SOC ROM and ITS NAND chips are, and earlier you wrote about some NAND

Hello everybody. The PP1V8_AWAKE line has a resistance of 6 ohms. Replacement of T2 is required. Is it possible to replace it with another one from the donor board? I would be glad if someone on this forum sells me T2, or a donor board. Thank you.

Ok i got you, thanks

To what temperature should the processor be heated? 210-220 Celsius is this normal?

After the firmware, the board's behavior has not changed ... I used this dump - https://boards.rossmanngroup.com/threads/820-00840-no-video-but-backlight-present.61055/post-74370

I'll try to flash the BIOS. Do you mean this one? https://boards.rossmanngroup.com/threads/820-00840-no-video-but-backlight-present.61055/

I put a non-working board in a fully working laptop and its behavior has not changed. There is also no image. The voltages are the same. Then I put the fully working board into the non-working laptop and it turned on. Thus, I found out that the matrix cable is working, and the trackpad is also...

At first it was, but after he showed the image, the voltage also changed.

Thank you. Do you mean that the problem is still with the matrix cable? My friend has exactly the same laptop, he will give it to me today so that I can connect my board to it. This way I will determine what the problem is. Am I doing everything right?

When the laptop showed an image, the trackpad cable was connected.

Code of my board is 820-00840-A. At the moment + 0.96V on CPU core, and the laptop restarts if it is running on battery power only. It works for 10 seconds, turns off and after 5 seconds turns on again, and so on endlessly. If you connect the charger, the laptop does not reboot, the CPU voltage...

When the charger is connected, the tester shows + 20V, and the consumed current is about 1.5 A.

Hello there There is no image. Before me, someone disassembled and damaged the trackpad cable, I measured it and did not find a short circuit in it. When turned on, all voltages are present. The fan starts only once for a few seconds and stops, while even with strong heat it does not turn on to...
