Hello Thomas, try this new build file from Lenovo maybe it helps you ...

Thank you! I tryed, but nothing happend;

Thank you! I tryed, but nothing happend;

Hello, try this file; it's the latest version released by Lenovo (1.32 (R1MET62W)).
If that doesn't work, then I'm out of ideas. Unfortunately, you'll have no other choice but to try it. I doubt it will work.
I'm afraid it's not a BIOS problem, but rather a possible hardware defect.
I've used your original Windows key; everything should be fine.
In my experience, with Lenovo BIOS chips starting with the 32 MB versions, it becomes increasingly difficult to create a new BIOS file from the extracted r1muj62w.exe files provided by Lenovo.
I get the impression that they're making everything more and more complicated and are no longer interested in repairs.
Just my opinion.

here is my bios image

I know I should create a dedicated post, but since we're here, I have a similar problem to the guy, with the same laptop.

Thinkpad P14s Gen 2

• Serial Number: PF393MZS
• Type Number: 21A0003PUS
• Ryzen 7 PRO
• 32GB RAM
• 1TB SSD m.2
• Motherboard: unknown

But I have a question about your BIN file, is it safe for me to use it? I mean regarding compatibility. I don't know much about this process, but I just bought my first ch341A and I understand that I'm going to commit a metaphorical homicide if I do something wrong.

Use 1.8V adapter with the CH341A, otherwise you'll damage BIOS chip or the board/CPU, if your BIOS chip looks like the picture on post 21 you need a WSON8 8x6 probe/pogo pin adapter, the SOIC8 clip which comes with most CH341A kits won't work on it
Read the contents of the BIOS chip and upload it here as .zip or . rar

Info from Lenovo Support:

Entladung statischer Elektrizität
Dieser Vorgang hilft dabei, eventuell im Gerät verbliebene elektrische Ladung zu entfernen:

1. Schalten Sie Ihr Gerät aus und entfernen Sie das Netzteil sowie alle anderen angeschlossenen Geräte oder Kabel.
2. Halten Sie den Netzschalter 60 Sekunden lang gedrückt. Das Gerät kann sich während dieses Vorgangs ein- oder ausschalten – bitte halten Sie die Taste dennoch durchgehend gedrückt.
3. Anschließend schließen Sie das Netzteil wieder an und schalten das Gerät wie gewohnt ein (der Startvorgang kann etwas länger dauern – dies ist normal). Überprüfen Sie, ob das Problem weiterhin besteht.

BIOS-Back-to-Boot-Funktion
Versuchen Sie, das Gerät mit der BIOS-Back-to-Boot-Funktion wiederherzustellen.

Drücken Sie im ausgeschalteten Zustand: Fn + 2 + Backspace + Power-Taste gleichzeitig. Drücken Sie mehrmals oder halten Sie die Taste 3s lang gedrückt.

Nothing helped

I ordered a new mainboard from UK via Ebay in the morning; https://www.ebay.de/itm/389066676855
