1. Remove the bottom plate

Let’s get that straight, you will be able to upgrade your laptop only if you have purchased a version, that comes with an SSD. If you get the 64GB eMMC model, you will not be able to upgrade it internally, as explicitly mentioned by Lenovo. However, if you need to get inside of the laptop, just undo all five Torx-head screws, and slide the bottom panel downwards.

2. Cooling system

Once you are inside, you can see the passive cooling setup in its full glory. There is one heat pipe that drives the heat away from the CPU, towards a metal sheet of paper in the middle of the chassis, which will naturally dissipate the heat away. Also, there is something that looks like a copper bracket around the processor, which should further enhance the thermal efficiency of the cooling solution.

3. Battery

When it comes to the battery, though, Lenovo has put a 37.5Wh unit, which should be enough, considering the display size, and the power efficiency of the processor.

Somewhere beneath large tablets, and small laptops, but more importantly - it is aimed at a younger user base.Obviously, it packs touchscreen support, but there are no mentions of stylus support or a Pen inside of the package. Also, the hardware relies on 6W TDP processors fr[...]

  • Wide I/O with a MicroSD card slot
