    Yoga 9 14ITL5 board number GYGB0 NM-C814 Rev: 1.0 USB-C Charge Issue

    I'm starting to notice a variation on Themes with these Lenovo Laptops.
    In this post https://www.badcaps.net/forum/troubl...-solder-joints
    I noticed the these similar looking Power Mosfets shown in attached image.

    Currently I haven't been able to find a schematic for the GYGB0 NM-C814 board.
    I can't clearly read the code on these overheated chips, but they don't appear to be the same.

    If anybody has any idea on how to identify this particular chip muchos gracias.
    I'm going to desolder the suspected failure and see if the pad connections match with the CSD87501L from the x1 carbon

    Post more pics of this region. I think they are the pico star-10 packaged dual mosfets. Will keep digging.

      Ohh forgot to update.

      The schematic I found claims its the CSD87501L.

      The markings were definitely a different manufacturer, but I swapped it with a CSD87501L and it works perfectly.
