A second display and good upgradability? That sounds like a great deal.
1. Remove the bottom plate
This device’s bottom panel is held in place by 9 Torx-head screws. After you undo them, you have to pry the panel away with a plastic tool. The easiest way to start is from around the hinges.
In terms of battery, this laptop is equipped with a 45Wh unit.
3. Memory and storage
Quite frankly we weren’t expecting to see upgradable memory, but thankfully, Lenovo has provided a single RAM SODIMM slot, which supports up to 16GB of DDR4 memory, ticking at 2666 MHz. Storage-wise, there is a single M.2 PCIe x4 slot.
4. Cooling system
As you can see, the cooling comprises two fans, a thick heat pipe, and a rather long heat sink.
