1. Remove the bottom plate

To get this laptop disassembled, you first need to remove the three rubber covers in the middle of the bottom panel. Then, undo all 13 Phillips-head screws and pry the panel starting from the front right corner.

2. Battery

Inside, we find a 90Wh battery pack, which lasts for 8 hours of Web browsing, or 6 hours and 30 minutes of video playback. To continue with the disassembly, unplug the battery connector, and undo the four Phillips-head screws keeping it in place.

3. Memory and storage

Here, you get either 8 or 16GB of DDR5 memory soldered to the motherboard. You can expand it by 32GB via the single SODIMM slot. Storage-wise, you get two M.2 PCIe x4 slots, which support Gen 4 drives.

4. Cooling system

This device has a really special cooling, which incorporates three heat pipes shared between the CPU and the GPU, as well as one more for each of them. A sixth heat pipe takes care of the VRMs and the graphics memory, while four heat sinks, and two fans help with heat dissipation. Also, the processor comes with a liquid metal thermal compound.
