    How to find the correct Mosfet on a laptop I need to replace

    I don't know if this is the correct forum or if I should be posting in another one. I have a broken mosfet that needs to be replaced on a yoga motherboard.
    The mosfet is labeled:
    SM
    3424n
    CX427

    I have found a replacement before searching a combination of these number but this one is giving me issues.
    Am I going about this wrong?

    Advice and any and all tips is greatly appreciated.

              Hi Diif,

              Thank you very much.
              So if I wanted to buy mosfets for my shop, should I buy multiple of one or is there a package bundle I could buy? I want be prepared for a lot more issues that come my way.
              I know I can buy books of caps and resistors is there any bundle of mosfets?

                  I've bought a selection of AO mosfets a seller had put together in the past but they don't come in books like the caps and resistors.
                  Take a look at this list https://www.badcaps.net/forum/showthread.php?t=84817

                      Lenovo IdeaPad 330 laptop mosfet issue
                      by ebyte64
                      Good day everyone.

                      I have been scratching my head with a Lenovo laptop I got in today.

                      The laptop had no power and taking no amps from the power supply. Checking voltage showed 20v only on one side of the first mosfet. Took it off and replaced it and then same story. Took off second mosfet and then the first mosfet had the right voltages as well as 25v on gate is it should. Replacing the second mosfet the problem started again.

                      Even using a wire to bypass the second mosfet does the same interference with the first mosfet.

                      Would anyone...

                      MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
                      by RdeveLabs
                      To all the members here...

                      Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

                      So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...

                      Acer Nitro AN517-52 FH51M LA-J871P Works on battery only. Won't charge.
                      by gadgettree
                      Hi there,

                      I am having trouble diagnosing this gaming laptop.
                      The laptop does not power on with AC Power only. The battery also does not charge. The laptop turns on when the battery is plugged in, regardless of whether or not the charger is plugged in until the battery dies of course.
                      So something is stopping adapter power from getting to the laptop. I checked Adapdet to make sure that the motherboard knows when the adapter is plugged in. That works fine.



                      I suspect the first Mosfet isn't turning on but I am unsure how to properly diagnose that...
