Hello, I have a T470 and don't have the BIOS password, and need to access it to be able to boot my notebook (it isshowing me an error in the boot and forcing me to enter setup to fix it, but I can't enter and consequently cant boot).

I don't have knowledge of what tools (software and hardware) I need to access it and read/write the BIOS and how to remove this password as was mentioned before in this post.

Can you, or somebodyelse here, send me any tutorial or teach me how to identify the correct chip in my motherboard, read the information, dump it to be able to send here or to manually remove this passaword (or identify it in side the dump to be able to use to login)?
