    Msi ms-7613

    Hi,
    I have a MSI-MS7613 that isn't starting. The PSU is OK, and when I try to start the fan spins once and stops. It starts to do this cycle until i switch it off. I found that a USB port had been shorted, and the respective fuse has blown. Today, it tried to turn on the motherboard without the additional power cord (4 pins) and it's apparently working, which tells me after reading some other posts from this forum that I have a MOSFET from the CPU VRM fried. The problem is to find it. Does anyone have a schematic for this board or any clue how I can solve this problem.

    Thanks.

      Ok,
      Just figured out that the mobo does not start without the fan connected and the CPU in place.
      Now it starts but nothing happens, no sound, nothing, just the fans running...

          After some digging, just found that i had some MOSFET shorted. The Major problem now is to find some replacements. Could someone tell me what mosfet can i use. The ones that were in place and are burned are Nikos PO903BD and Nikos PO603BD.

          Thanks in advance.

              first you must change or desolder USB fuse like that

                  How do you test MOSFET in laptops ?
                  by Jane
                  I tried to use this method:

                  Testing an N-channel MOSFET:

                  Step 1: Discharge the Gate (turn off the MOSFET)
                  Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
                  Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.

                  Step 2: Charge the Gate (turn on the MOSFET)
                  Now, place the red probe on the Gate (G) and the black probe on the                  ...

                  Help identifying mosfet on Razer Blade RZ09 (CH570_MB_NT)
                  by redbaron1007
                  I have a Razer laptop (RZ09 MB# CH570_MB_NT) that has a shorted mosfet marked BND M03 E067 that I'm unable to find anywhere online. Does anyone either know what the part number is for this mosfet or have a schematic I can find it in?

                  Backstory on the whole thing the laptop was plugged into a lamp at a hotel. The lamp got unplugged while it was charging and now the system won't power on anymore. I found the caps around this mosfet shorted and when I injected voltage into the caps the mosfet got hot and my bench psu was pulling 5A. Pretty sure this is all that's wrong with the laptop...

                  Asus X712EA 3 volts after the first mosfet
                  by AppleLover123
                  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...

                  ASUS ROG Zephyrus GPU Mosfet repeat failure
                  by MicroSMD Lab
                  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...

                  Asus GA502D keeps blowing mosfet
                  by Scotchmist
                  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
