The EC chip is located directly below the Main BIOS chip. I managed to do everything according to the given instructions from the mentioned post. Thanks!

Now I have another problem, which is that I'm getting an 'Intel Thunderbolt Retimer Firmware Update failed' error, and because of that, I can't update the BIOS.
I also noticed that it now takes more time before Windows starts loading. What could be the problem?...

Thank you for your response.
I believe the suggested solution in that post works, but I don't know where the EC chip is located 😓 Is it on the other side of the motherboard?
My version is V75.

Can someone help me with the BIOS password?
Thanks in advance!​...
