Default Re: Books on Laptop Motherboard Repair

It might not be well written but it did fill in missing pieces of knowledge that I was lacking or not fully understanding all of it

The part that fill in some missing piece was the explanation of the data lines and how they are created and what they should look and what it means if it —>

value = “0” and stays that value or if the value is “3.3 volts and stays at that value

Thanks for sharing this
