1. Remove the bottom plate

To access this laptop’s internals, you need to undo a total of 7 captive Phillips-head screws. Then, pry the bottom panel starting from the back, and lift it away from the chassis.

2. Battery

Inside, we find a 90Wh battery pack. The first thing you need to do is to unplug the connector from the motherboard. Then, undo all 4 Phillips-head screws holding it to the body. After that, carefully unlatch the speaker cables from the battery. We found it easier if you gently lift one of the runners, which loosens the tension of the cables.

3. Memory and storage

Here, we see two SODIMM slots, which fit up to 64GB of dual-channel DDR4 RAM in total. Storage-wise, you get two M.2 PCIe x4 slots, one of which supports Gen 4 drives.

4. Cooling system

As for the cooling, there are two heat pipes, two heat sinks, and two fans doing the hard work. Additionally, we see two heat spreaders, which cool the VRMs and the graphics memory.
