Humm no explanation and use tinfoil instead of proper tape 🙂 that was a mosfet he
removed, But job well done guys its basic follow the power rails. 19V, 3V, 5V Rails
some mother boards might use one mosfet for multiple voltages so its not as
easy as it looks..But this would be alot better with explanation

Robert Fowler says:

Should always discharge gate on mosfet by shorting source and gate with finger or tweezers before checking mosfet, N channel mosfets will turn on with just a static charge , touching positive multimeter lead in diode mode on gate will make mosfet conduct in both directions. false short etc.
