Hallo i trying to learn how to troubleshoot/diagnose laptop motherboards. I have here Huawei matebook x pro i7/16gb.[br]
[br]
Laptop wont start only keys capslock and fn lights light up and fan start spin for 3 seconds bud light stay on. And power light just blinking.[br]
[br]
My steps what i done.[br]
- At first i see blown mosfet, ok i replaced it with new one (still dont help) - i am wondering what can couse the mosfet to blow[br]
- find lot of shorts on top site on the board (i think it is a shorted cpu but it is unlikely to be cpu it is rare)[br]
- and i dont know what to do next maybe someone can help me figure it up.[br]
[br]
