    Lenovo Yoga Pro 9 14IRP8 - help identifying what exploded in the motherboard

    Hello everyone,
    I hope this finds you doing well.

    I need some help identifying what and how important is that exploded in my laptop's motherboard.
    Photos attached.

    My laptop is a 1 month old Lenovo Yoga Pro 9 14IRP8 (83BU), i9-13905H, RTX4070, 64 GB ram.
    It was in the charger, and I was excited to play FC24 for the first time, but when the loading screen came something exploded in the laptop and it shut down.
    It didn't turn on for about 30 seconds after that, but then it turned on and has been working seemingly perfectly (at least I didn't notice anything, and the lenovo vantage hardware tests didn't show any issue) since, for about 2 weeks now.
    The laptop still works with nothing seems to give me a problem, I even had played Cyberpunk 2077 without any hiccups.

    Probably one of the same tantalum caps in the same region. They are shitty by design. When they die, they short circuit. We do not use them in any of our designs.

    you can compare the size of the removed part against the small black body tantalum capacitors you posted in the pics. Being a bulk cap, it will not be missed.

      Thank you for your help!

      As am not knowledgeable enough about hardware, I tried calling warranty but they didn't seem to be willing to help especially since the laptop is working fine, and they haven't updated me yet what they are going to do.
      If it's not going to be missed, I will save myself the effort of calling back warranty.

    As mon2 said it is just caps
    the best thing to do is replaceing the three of them at any expert repair shop and no need for warranty or simply remove them if you have a some soldring skill

      Thank you friend, but unfortunately I have tried soldering only once in my life and I wouldn't want to to experiment on my one month old laptop.
      If it's not urgent, I will deal with it once I gain more knowledge and train on the waste boards I have.
      I really appreciate the help!
