1. Remove the bottom plate

There are 13 Phillips-head screws holding this laptop’s bottom panel in place. After you undo them, pry the panel with a plastic tool, and lift it away from the chassis.

2. Battery

This laptop comes with a 53.5Wh battery pack. It lasted us nearly 6 hours of Web browsing, or 5 hours and 30 minutes of video playback. To take it out, unplug the battery connector, and remove the three Phillips-head screws keeping it attached to the chassis.

3. Memory and storage

The upgrade options here are pretty good. You get two RAM SODIMM slots for up to 64GB of DDR4 memory, working in dual-channel mode. Storage-wise, you get two M.2 PCIe x4 slots that support Gen 4 drives.

4. Cooling system

The CPU is being cooled by two thick heat pipes, while the three thinner ones are cooling the GPU. Thankfully, both the graphics memory and the VRMs have a heat pipe managing their thermals.
