Hey guys,
i have a asus motherboard here and as the title says after the first mosfet (in the picture) there is nothing more than 3.15v.
I injected 19v and max. 1 amp at the charging port and there is not voltage drop or smth. It's just taking 19v and 1 milliamp.
Then i tried to inject 19v and max 1amp after the current sensor and there it first takes 19v and 4 milliamps and after 2 seconds it is taking nothing (no current).
I measured on the coils on board everything seems fine. Also the main power rail is not shorted (infinite resistance).
Now i thought something... -
I have an Asus GA502D, it had a blown mosfet which I replaced and the laptop booted into windows, a few mins later it shut off, the same mosfet was blown. I thought maybe just a bad mosfet but same thing happened again, a few mins in windows and shuts off.
I have removed the mosfet and can run the laptop no problem
The MOSFET is FDPC5018SG
Can anyone point me in the direction of what could be the cause of this, could it be the controller rt3663bc?
Thanks -
The board number is GU502DU. I repaired this a couple weeks ago and it came back with the same issue, same mosfet failed (PQH9201). I'm hoping that the GPU was spared this time.
I used the same replacement part (purchased from Mouser) and I'm certain the soldering was done properly since it took just as much effort to remove as before. What could cause this same mosfet to fail? I'm thinking if it was unsuitable then the others would fail too. I looked for similar failures on YTube and the mosfet was replaced with AOE6930 in one instance and AOE6932 in the other but it's possible that the... -
I'm not new to this board but this is my first posting so I hope I'm doing this right. I'm looking for the schematic for a ASUS N550JV motherboard P/N: 60NB0860-MB1B10. I have the board view but need the schematic also. TNX07-31-2025, 07:12 PM -
I recently bought this laptop to try to fix up because it was so cheap. It has no power so I figured it was a MOSFET or cap issue so I started with taking it apart, but when I had it apart I noticed one of the MOSFETs was missing. I'm new to this so I don't know where or how to look up what to replace it with. I do have the boardview for it so I somewhat know what was there which I attached ,and the missing piece is PQ303....
