In this guide I will show you how to remove Asus ZenBook 14 UX433FN bottom cover, I will also remove the SSD, battery, heatsink, cooling fan, speaker, touchpad, keyboard, palmrest, motherboard, and screen.
Teardown is what we do! Follow us on Facebook for the latest repair news.
It can be seen that the air inlet at the bottom is not really large, and the main air inlet should be on the other side of the LCD hinges. We also noticed that there is a small gap in the front of the fuselage, which also shows that the Asus ZenBook 14 UX433FN is a thin and light laptop that can support one-handed opening and closing.
The bottom case is fixed by 9 visible screws, but you need to pay attention to the screws under the two foot pads.
After removing 11 screws, insert a plastic thin tool under the bottom cover and slide the tool to unlock the latches that securing the bottom cover to the palm rest.
The internal layout of the Asus UX433FN is perfect; each part is neatly placed and has a high internal space utilization.
There is a metal piece on the battery to fix and protect the battery. This design is the first time I saw it in a thin and light laptop.
Since the battery occupies nearly half of the space inside, the battery capacity reaches 50 watts, which is relatively large in an ultrabook.
Disconnect the battery cable from the motherboard and remove the screws that secure the battery to remove the battery.
Under the battery, we can access the touchpad module and the keyboard cable, on the right side of the battery is M.2 SSD.
The size of the speaker is still relatively large, which can bring good sound effects.
The Asus ZenBook 14 UX433FN comes with a Western Digital 512GB NVMe M.2 SSD, which uses a multi-chip stack design, so the effective area of the board is quite small.
Remove three screws that securing the touchpad and take out the touchpad.
The surface of the touch panel has a layer of glass, which can give users a very good touch feel.
Remove three screws and disconnect the fan cable from the motherboard, then take out the cooling fan.
It can be seen that the fan is very thin, but the fan blade area is not small, so even a single CPU fan can bring considerable air volume.
The motherboard is divided into two parts by the fan, so there is a yellow cable to connect the two circuit boards.
It is worth noting that the LCD hinge is securing on the motherboard, and it is also securing the LCD cable.
The LCD hinge on the right side not only the securing the circuit board, but also securing the heatsink module. So we need to remove the LCD hinge before we can continue the disassembly work.
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?
What on earth is the Torx screwdriver size used to unscrew the 11 bottom screws, 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!
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.
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!
Have an Asus ux433 with 8 RAM. Can I remove this one and put the other one of 16 RAM?
Obviously, it does n’t work. The memory is soldered to the motherboard, and no free memory slots are reserved.
possible if we replace the ram with remove the soldered and replace a new one
Yes, but you need to go to a professional repair shop, but only a few repair shops can provide this service.
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?
hi, I got this laptop but the hinge seems a bit too lose, how can I replace it or fix that? thanks!
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.
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?
can I insert in slot m.2 an intel optane 32 GB +512GB nand?? Can share your opinion on this is?? Thank you.
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.
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.
Hi,
Is IT possible to use an AX210ngw wifi 6 adaptor on this laptop? Is an M.2 Wifi slot available?
Thank you!
The wifi card of this laptop is soldered on the motherboard, and there is no M.2 port reserved for the wifi card.
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
How and where other than ASUS can you get a replacement ScreenPad from? I have 1/5 not working
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 palmrest via plastic rivets that would require being melted to remove the keyboard.
Thanks again!
On 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.

Is there any CMOS battery? I can’t find it.
This laptop doesn’t have a separate CMOS battery, it has a CMOS battery as a module as well as integrated into the battery.
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!
Yes, you’re right.
