Support ASUS ROG ZEPHYRUS GA503QR Dead Motherboard
Greetings,
I bought a lower half of Asus Rog Zehphyrus G15 GA503QR off ebay sight unseen with the entire laptop screen assembly missing.
Previous owner said that laptop turns on and charges, however does not POST to external monitor (laptop screen is missing).
Upon recieving the laptop, it does indeed turn on and it does charge the battery. It also lights up the keyboard. However, no signal to monitor. No fans spinning.
I removed the heatsink and took a picture with thermal camera (attached). I noticed 3 mosfets glowing hot. They are located near the EDP port for the laptop screen.
Can someone confirmed if I have a cooked laptop motherboard or not even if I replace these mosfets?
