Due to the nature of Chrome OS, Chromebooks are more complete units. What we mean by that is, you won’t really be able to make some changes. At least not without a soldering iron.
1. Remove the bottom plate
Despite its relatively small size, there are 12 Phillips-head screws holding the bottom panel in place. After you undo them, carefully pry the plate with a plastic tool, preferably starting at the back – around the hinges, where it would be easier to stick your… tool in.
Last but not least – a 39Wh battery. When you consider the tiny display, efficient chipset and the naturally unpretentious Chrome OS, it should deliver a great battery life.
3. Motherboard and Wi-Fi card
Now that we are inside, we can see something expectable – the motherboard is placed upside-down. This prevents us from seeing how the cooling solution is assembled, but by the lack of fan spinning around, we place our bet on a passive single plate. Additionally, upgrading the memory is impossible as the 4GB of LPDDR4 modules are soldered to the motherboard.
While 64GB of eMMC storage is not something to write home about, it is still good to see that you can upgrade it via the MicroSD card slot.
On the image below, you can see the WiFi card of use here. It is made by Intel and has a model number 9560NGW. It supports the 802.11ac WiFi standard.
