Laptop MSI GT62VR 6RE
CPU: SR2FL Intel Core i7-6820HK
dGPU: N17E-G2-A1

Padła w nim karta graficzna. Totalne zwarcie na zasilaczu . Laptop się nie uruchamiał.
Po wyjęciu karty zwarcie ustąpiło.
Karta była MS-1W0V1 VER:1.0
Włożyłem nową kartę MS-1W0V1 VER:1.2
Widać że laptop się uruchamia. Dioda led od hdd mruga jakby startował system.
Niestety brak obrazu na ekranie jak również brak na HDMI.
Zamieniłem vBios kart ale to nie pomogło.
Dalej brak obrazu.
PCB kart wydaje się identyczne.
Nie stwierdziłem różnic.

Does the CapsLock LED on the keyboard respond to pressing the CapsLock button?

There is no LED Capslock on a laptop, but the LED Capslock on the external USB keyboard responds to pressing the Capslock button. Numlock also responds.

Does the GPU chip on the MXM card gets hot when the machine is turned on?

Measure the following voltages to ground, when the machine is turned on with the MXM card inserted:
- Directly on capacitors C399, C522, C606
- On pin 2 of resistors R19, R40, R145.
- On pins 6, 16, 26, 32, 34, 156 of MXM card connector CONP3.

Did you mean U741? UP9509P
He is on the other side of PCB and it is not possible to measure during work. No access.
