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

The connection between the I/O board and the motherboard is connected by a yellow cable, and there are screws to fix the connector, which ensures the stability of the connection between the I/O board and the motherboard.

The various components are still neatly arranged on the front of the motherboard. They mainly consist of Intel processors, MX150 graphics cards, and 8GB memory.

This laptop has 8GB of memory soldered on the motherboard. It does not have a free memory slot, so upgrading the memory is impossible.

This is the Intel Core i5-8265U processor.

This is an 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.

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 underneath the screen assembly. This pad acts as a cushion and prevents the screen from touching the human body when it is fully opened and closed.

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

  1. My new UX433FN has a few millimeter lifts 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. Would you mind sharing your opinion on this?

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

    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 one.

  4. Hello, I have a UX433FN that suffered water damage. I opened it up for drying and 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 to check what it has, or if you have high-resolution pictures of the motherboard that might help repair it. Thanks!

  5. I have an Asus UX433 with 8GB of RAM. Can I remove this one and put the other one with 16GB of RAM?

    1. It doesn’t work. The memory is soldered to the motherboard, and no free memory slots are reserved.

        Is it possible to replace the RAM by removing the soldered RAM and replacing it with a new one?

        1. David Tian

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

          1. Andres Rogers

            Is it possible that something gets broken while removing the soldered RAM, and my PC will remain inoperable forever?
            Or is there zero risk that it will break?

  6. Hi, I got this laptop, but the hinge seems a bit too loose. How can I replace it or fix that? Thanks!

    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.

  7. Whenever I unscrew all screws (also under the rubber pads), I can’t remove the bottom plate because it feels stuck/glued in the center of that plate.
    Any tips?

  8. Can I insert an Intel Optane 32GB 512GB NAND in slot M. 2? If so, can you share your opinion on this? Thank you.

  9. Thank you so much for the guide. I fixed two issues: the touchpad was slightly lifted, and the hinges were loose.

    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.

  11. Hi,
    Is it possible to use an AX210ngw Wi-Fi 6 adaptor on this laptop? Is an M.2 Wi-Fi slot available?
    Thank you!

    1. David Tian

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

  12. Where else can you get a replacement ScreenPad besides ASUS? I have 1/5 not working

    1. David Tian

      You can try searching for it on eBay.

    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 palm rest via plastic rivets that would require being melted to remove the keyboard.
    Thanks again!

    1. In this picture, you can see the keyboard; only a few plastic rivets hold it in place. You need a soldering iron to remove the keyboard very easily.

  14. Is there any CMOS battery? I can’t find it.

    1. This laptop doesn’t have a separate CMOS battery. It has a CMOS battery as a module as well as integrated into the battery.

  15. I’m not sure if I understood this correctly: “It has a CMOS battery as a module.” What do you mean by that?

    Did I understand this correctly?:
    There is no CMOS battery. The main battery serves as the CMOS battery.

    Thank you for your reply!

    1. Yes, you’re right.
