1. Remove the bottom plate

To get inside of this notebook, you need to undo 10 Phillips-head screws. On our unit, 6 of them were captive, while 4 detach from the bottom panel. After you undo them, pop the panel with a plastic tool and lift it away from the chassis.

2. Battery, memory, and storage

A bit surprising is that it comes with a relatively small 45Wh unit.

In terms of memory, this laptop comes in two iterations – one with 4GB and one with 8GB of soldered RAM. Additionally, you can put 32GB more thanks to the single SODIMM slot. Keep in mind that the integrated memory is capable of running in dual-channel mode, so for the best performance, it is advisable to pair the soldered chips with the appropriate amount. Storage-wise, we see two M.2 PCIe x4 slots. Interestingly, Lenovo says that their laptop can fit a 2.5-inch SATA drive, however, we see no bracket, nor a cable included with the machine.

3. Cooling system

Even though this device comes with a ULV processor, the cooling solution looks good. There are two thin heat pipes, which lead to a rather long heat spreader. And the heat is blown away with the help of a pretty large fan.
