    ASUS X555LD - no voltage after first mosfet

    hello.
    Have this ASUS X555LD, that have no voltage/0.88V/ after first mosfet. on gate of it is same little voltage

    my measurements give nothing for me and jumping fist two mosfets bring it to life, so there must be problem in this charging side

    replaced that BQ24735 with known working one, but readings are the same

          Yep common fault on Asus boards. Still not sure what causes that.

                  Do you have shorts after mosfets

                      MOSFET? Is its voltage reading normal?
                      by alro7779
                      Hello, guys!
                      Got this 8-pin MOSFET (I presume) on the motherboard that I'm still trying to repair (HP Stream 11-ah117wm DAY0HGMB6C1 REV:C), close to the DC IN connector, and when I read voltage on Drain (5-8 pins) and Source (1-3 pins), I got the 19.81 VDC of the DC IN on each, but on the Gate (pin 4) it's 25 VDC. Is it normal? Now, I'm not quite sure the component is a MOSFET, but it looks like, and since it has the printed code on it totally unreadable, I can't try to find the datasheet. Can anyone give me a hand on this? Or maybe ff there's some MOSFET tutorial or something that you can...

                      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

                      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...

                      Odd MOSFET only on some ASUS x99/x299/z370 motherboards..
                      by Timp74
                      Hi All,
                      Could anyone comment on the purpose of the MOSFET circled in red in the attached photo of an ASUS ROG X299 Extreme VRM?

                      I'm trying to fix an ASUS motherboard(WS x299 SAGE) with a similar VRM where this MOSFET has burnt out along with one of the IR3555m driver chips. From looking at photos of motherboard VRMs on the internet, it seems only some ASUS motherboards have a MOSFET like this. Although I've seen some photos of ASUS z370 boards where it's not populated. The MOSFET is usually a NTMFS4C06N. It has its drain connected to the output of the Vcore VRM, and on...

                      ASUS TUF GAMING Z790-PLUS WIFI - BIOS Help
                      by grimacelord
                      Hello,

                      I have spent the last hour on this and I guess this is just over my head, so here I am.

                      I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard here that needs to have the BIOS updated in order to accept the latest CPUs.

                      The BIOS chips seem to come as a set of two: GD25B64ESIG and GD25B128ESIG. My guess is one of them is a fail-safe for the main BIOS? I really don't know. Or one of them is ME and other is BIOS? I don't know.

                      Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website...
