    Lenovo Ideapad 5 LC55-14A MOSFET identification

    Hi guys, grateful if anyone can help with identifying part number of the following MOSFET.

    Laptop: Lenovo Ideapad 5 Flex 5-14ARE05
    Motherboard: LC55-14A 448.OK104.0031

    Location on board: PU5102
    The MOSFET next to it is the PK650BA

    I want to be totally sure of the one that was previously installed there, if someone has the same board and can confirm which component was located there, I would greatly appreciate it.

    I can't seem to find schematic for this motherboard.
    From now, thank you for you help

    What is the charger IC on this logic board ? Post the full markings on the topside of the charger IC.

      The Charger IC on this board is the BQ25710, but that IC is far from these MOSFETs, that missing component is on a par with the RAM memories

        Ok. From a few google searches, this logic board is also marked with "LA-J701P" in the silk screen?

        Please confirm.

                please can you provide the ISL chip information/part number near to the USB-C connector ? They are two and I have the TPS6602 already. Please I need the other part number. Thank you
