Asus ZenBook 13 UX333FN Disassembly and RAM, M.2 SSD upgrade options


In this guide, I will disassemble an Asus ZenBook 13 UX333FN. I will remove the bottom case to access the battery, SSD, Wi-Fi card, cooling fan, speaker, heatsink, and motherboard.

As with other ultrabooks, we need to remove the bottom case before we can access its internal components. As you can see from the picture, there are nine visible screws on the bottom case, but after removing these screws, you still can’t remove the case. There are two screws under the two foot pads near the LCD hinges. You need to remove the footpad with the blade first, then remove the two screws under the footpad.

After removing the bottom case, you can access most of the internal components, including battery, speaker, SSD, I/O board, heatsink, cooling fan, and motherboard.
It can be seen that the battery occupies almost half of the space, and the layout of other components is also very compact and neat.
