    Help in identifying a MOSFET - ASUS ROG GU603Z

    I have a ROG here which isn't charging and found 2 MOSFETS to be faulty with no schematics available only board view. I need help in finding a replacement (equivalent)

    The markings are G4 GUB and under this it says 2Y2701. I've tried googling this but no joy.

    Can anybody shed some light on where to get them from or an equivalent.

    Thanks

    Which battery charger chip is onboard? Post the full topside markings. If the Texas Instruments BQ series then these are common N-channel mosfets.

        Would this be ok as an alternative?

              Theres no need to apologise for anything. piernov has some good info about choosing a replacement mosfet over at his wiki, it might help you https://logi.wiki/index.php/User:Pie...iginal_part.3F
