LENOVO Thinkpad L14 Gen 4 Type 21H1, 21H2 Bios

[Stolperbein]

Have a nice day, I hope I'm in the right place and you might be able to help me.

L14 Gen 4 (Type 21H1, 21H2) Laptop serial number: PW- 08ZAEC / type number 21H2-S64440 / chipset is a Winband 25Q128JV

This no longer starts and the power LED is off, so I read the chip using the CH341A programmer. Which probably worked, but the file is empty. Hence my questions, it could be because the power LED is not lighting up (only mains operation, same problem).
If this could be the case, there is a bin file for this ThinkPad L14 Gen4 Intel. I've been researching for several days but haven't found any and also rewriting from EXE to I've had no success. P.s I'm just a small hobbyist so sorry if I'm not using technical terms.

Thanks for your help and feedback as to whether I can throw the part away.

What should we do with this? What's your problem?

post the S/N, post the original content of the bios chip, the motherboard model, etc.
