1. Remove the bottom plate

To access this notebook’s internals, you need to undo 5 captive Phillips-head screws. Then, pry the bottom panel with a plastic tool such as a guitar pick. It would be best to start from the back.

2. Remove the battery

Inside, there is a 51.3Wh battery pack. It lasts for 13 hours of Web browsing, or 9 hours of video playback. To take it out, remove the four Phillips-head screws holding it in place, and unplug the battery connector from the motherboard.

3. Upgrade memory and storage

Here, we see two SODIMM slots for up to 32GB of DDR4 RAM in dual-channel mode. Now, the storage comprises one M.2 PCIe x4 slot on the right, and one M.2 PCIe slot on the left, which is only accessible if there’s no LTE card installed.

4. Cooling system

As for the cooling, you get one heat pipe, connected to a heat sink, and a fan of medium size.
