However, from the side view, this heat pipe still has a certain thickness, and with its width of 8mm, it can also achieve a good thermal conductivity.

On the front of the motherboard, the various components are still very neatly arranged. They mainly have Intel processors, MX150 graphics cards and 8GB of memory.

This is 8GB of memory soldered on the motherboard, this laptop does not have a free memory slot, so it is impossible to upgrade the memory.

This is Intel 9560 Wi-Fi adapter with Bluetooth 5.0. It is soldered directly to the motherboard, so it cannot be replaced.

There is no important chip on the back of the motherboard, and there is no insulation sticker, but there are a lot of black insulation blocks on the back of the motherboard.

After the motherboard is removed, you can access the keyboard. Its keyboard can be separated from the palm rest, but it may be more difficult.

There is also a foot pad below the screen component. The purpose here is to not touch the body when the screen is fully opened and closed and at the same time play a buffering role.

Through this complete disassembly of Asus UX433FN, it is not difficult to find that in such a small body, Asus has utilized the internal space to the extreme, and compared with the traditional size of the laptop, there is no reduction, but more exquisite, which is the best proof of the design ability of the manufacturer.

  1. My new UX433FN has a few millimeter lift on the bottom right hand of my touchpad. It’s not very noticeable and you’ll only feel it when you run your fingers from the palm rest to the touchpad. Given that this is a brand new laptop, I don’t suspect that this is battery related. Care to share your opinion on this?

  2. What on earth is the Torx screwdriver size used to unscrew the 11 bottom screws, can’t find it anywhere

  3. Hi,
    is it possible to add one more SSD or is the motherboard limited to connecting a single SSD?
    Thanks in Advance!

    1. Yes, this laptop has only one M.2 slot, there is no way to add more SSDs, but you can replace your SSD with a larger SSD.

  4. Hello, I have a ux433fn and because of water damage, I opened it up for drying then sent it for repair. The repair people say the motherboard is missing some pieces, so I was wondering if you still have the motherboard for checking what it has or if you have high resolution pictures of the motherboard that might help repair it. Thanks!

    1. Obviously, it does n’t work. The memory is soldered to the motherboard, and no free memory slots are reserved.

        1. Yes, but you need to go to a professional repair shop, but only a few repair shops can provide this service.

          1. is it possible that in the process of removing the soldered Ram, something gets broken? and my PC stays inoperable forever.
            Or there is 0 risk that it will break?

    1. This is not a particularly good solution. You can remove the existing hinge and replace it with a new one. You can go to youtube to search for relevant videos.

  5. Whenever I unscrewed all screws (also under the rubber pads) I can’t remove the bottom plate for it feels stuck/glued in the center of that plate…
    Any tips?

  6. Thank you so much for the guide. Thanks to you I fixed a problem with the touchpad being slightly lifted and the problem with my hinges being loose.

  7. Can anybody tell me what size screws are needed to replace the t5 base screws? I successfully replaced the screen, but three of the base screws got mangled.

  8. Hi,
    Is IT possible to use an AX210ngw wifi 6 adaptor on this laptop? Is an M.2 Wifi slot available?
    Thank you!

    1. The wifi card of this laptop is soldered on the motherboard, and there is no M.2 port reserved for the wifi card.

  9. Thanks, such a great overview. Wish I had seen this a year ago.

    I have this laptop. 3 major issues.

    1) Wifi card died and from what I can see it is soldered to the board so not even an expert can replace this. This is really bad as Wifi cards often fail or are outdated. USB Wifi dongle does not see all WiFi Networks, so its like the Wifi card has killed wifi capability but I cannot rip it out.
    2) Does not charge via USB-C
    3) Number pad seems to activate and cant turn off when using a USB dock (tried multiple docks as well). Also number pad/ touch mouse feels cheap and not great to use

  10. Hello!
    Thank you for such a great teardown resource! Question for you – you stopped short of removing the keyboard and said it might be difficult to remove and replace it. What do you mean? Is this something best left to the pros? I have just the replacement keyboard, not a keyboard and palm rest assembly. I was afraid you meant this was one of those laptops that the keyboard is attached to the palmrest via plastic rivets that would require being melted to remove the keyboard.
    Thanks again!
