    Really good video!!
    I would love to see another video where you go a little bit more into how to figure out where lines are coming from. Basically what you did now with the tracing the power path, but maybe with a bit more explaination. I am often confused on where a line is coming from or where its going, especially when looking at apple schematics.

    • @platinumphonesandcomputers
      @platinumphonesandcomputers  2 года назад +1

      Oh I get what you are saying, actually a simple way to know the direction of power flow in schematics is from left to right, on top of that you can also the arrows at the end on the line, plus trace for words like "in" and "out"

    So in my case, on that mosfet, from ground to drain i have close to zero volts and between gate and drain or gate and ground i have just 0.6V
    But i have no schematics and obviously not enough knowledge. Is it possible to be just the mosfet? I know, they don't usually die alone, but it would be a personal achievement to repair this laptop, if you could give me a hint
