Hello
Maybe someone knows how to identify a burnt element on the board?
It sits on the board called PQA1.
I only found out that this is a MOSFET, which is responsible for power supply and without which the laptop simply does not connect. It has 10 contacts (8 legs and 2 at the bottom).
Maybe someone can identify the element and tell me which one I need?
I would also be grateful for instructions on the type "How to identify"
I have a motherboard diagram and a document with what is connected to what, but I don't understand it well...
Motherboard: Compal GH51M LA-K862P 1A

PQA1 is a EMB09A03VP dual N-Channel MOSFET in DFN3X3 casing.

If the component is so burnt that you cannot read its markings, the only few ways to determine its actual part number are:
- schematic diagram,
- boardview file with components description,
- donor board of the same PCB markings,
- asking on our forum.
