I installed the latest SW RT809HSE_20250423_ENG.exe and realized, that the SW-package seems to be faulty: the main exe file is missing. So I am now using RT809H_RT809HSE_20241125_ENG.exe.
edit: Found the reason for the mysterious vanishing of the exe

Except an ID error I could not get any useful reading. I'm using a Pogo-Pin adapter, may be I have to desolder the chip.Leave a comment:

sorry, my fault. I mixed up two laptops.
In the meantime I have found my mistake, a very stupid mistake: when writing 00 in the area starting with 0003EF00, I accidentally had 8 bytes starting with 04 07 in the HexEdit buffer instead of starting with 00 00. Apparently the laptop complained about wrong SVP data.
So the procedure for deleting the password is exactly the same, as for the E14 Gen3 (AMD)....Leave a comment:

When writing 00 into these two areas, the laptops says "Bad SVP data, process stopped".Leave a comment:

I don'r know, if someone before me already tried to remove the password. I noticed, that the area starting with 0003D3C0 was somehow cleaned.
Ok, I'll try to write 00 into these two areas.Leave a comment:

Hi, I have an E14 Gen 2 AMD with a BIOS password.
MTM: 20TA000EGE S/N unit: PF39P83A S/N board: L!HF1A6056Z
I tried to delete the areas starting with 0003D3C0 and 0003EF00 in the EC dump, as I did for an E14 Gen 3 AMD. But here this didn't work.
Would be nice if someone could tell me which areas I need to delete.

I also recommend buying a more expensive programmer that has a chip that improves the signal quality. It makes the reading much more reliable.Leave a comment:

this is how I do it...

what programmer for Winbond W25R256JW
Off topic, but I think I have the best chance to get an answer here: Which programmer can read a Winbond W25R256JW (not W25R256JV) ? -
Schematics for ThinkPad L13 Yoga Gen 4 AMD
Can anyone provide the schematics for a ThinkPad L13 Yoga Gen 4 AMD? -
>>>> i was beginging to think maybe a too large charger could make the EC go to protection mode?
It sounds strange, but I made a similar experience with a Lenovo X380: it did not start with an original Lenovo 230W charger, but it started with a 90W charger.Leave a comment:

So far I have not been able to solve the problem. I have tried using hot air and cold spray to locate the defective chip, but to no avail.Leave a comment:
