1. Remove the bottom plate

To take this laptop apart, you need to undo 10 Phillips-head screws. After that, pry the bottom panel with a plastic tool. Then, you can lift it away from the chassis.

2. Battery

Inside, we see a 42Wh battery pack. If you need to remove the battery, first you need to unplug the connector from the motherboard. Then, undo all 6 Phillips-head screws, and take it away from the laptop.

3. Memory and storage

This device can be found with 4, 8, or 16GB of memory soldered on the motherboard. In addition, there is one SODIMM slot, which fits up to 32GB RAM modules. In terms of storage, there is one M.2 PCIe x4 slot, as well as a 2.5-inch SATA drive bay. It’s good to know that ASUS supplies the mounting accessories inside the box.

4. Cooling system

And for cooling, you get two heat pipes of different sizes. They connect to a heat sink, where the medium-sized fan blows the heat away.

Thank you for the information.
I found the specs of the PCIe slot on the Asus Web site:
M.2 2280 PCIe 3.0×2
i.e. It appears that only two of the four PCIe lanes will be active for the installed SSD. I assume that means a PCIe x4 drive will only ever work at half speed on this laptop.
