1. Remove the bottom plate
You need to undo only 5 captive Torx-head screws to access this notebook’s internals. Then, pry the bottom panel with a plastic tool. It’s best to start from the back.
2. Remove the battery
Our configuration features a 51.3Wh battery pack. It got us through 13 hours of Web browsing, or 10 hours of video playback. To remove it, unplug the battery connector, and undo four Phillips-head screws that keep it in place.
3. Upgrade memory and storage
Memory-wise, you get two SODIMM slots for up to 64GB of DDR4 RAM in dual-channel mode. Respectively, the storage options comprise one M.2 PCIe x4 slot with the support of Gen 4 SSDs.
4. Cooling system
As for the cooling, you get one heat pipe, which leads to a heat sink. There a single fan blows the heat away from the chassis.
