Hi, I am Joseph from the UK.
I stumbled across this forum after I bought an X270 with a locked BIOS for parts - which I have now unlocked thanks to the tools here!
I must confess while removing the BIOS chip for dumping / flashing, I accidentally knocked off and damaged a small capacitor. When looking for a replacement part, I found full schematics for the X270 on this very site!

Thank you to everyone involved for this incredible resource, I wish I had known about it sooner.
