Case, design, and build quality

Lenovo used a sturdy aluminum case for the S540, so there is virtually no flex when handling it. Thanks to the 19:10 aspect ratio of the display, the usually fairly large bottom bezel has been replaced by the taller display. So you get more screen real estate in a laptop that is the same size as competing models with 19:9 aspect ratios.


Left: 2x USB-C

Right: Power button, 3.5mm audio jack, USB-A 3.1

The port selection is fairly standard for this class of notebook. The USB-A port is a nice addition, but it would have been good if Lenovo had put one USB-C port on the left and one on the right, so the charging cable could be plugged in from any side.

The display stands out among competing AMD laptops for not having any glaring weaknesses: The brightness at 300nit, while not amazing, is at least usable in a bright indoor environment. But the biggest surprise is the 2560x1600 pixel resolution with a 19:10 aspect ratio, which is pretty rare. Additionally, the panel covers 100% sRGB.


Although the IdeaPad is supposed to be Lenovo's budget line, the AMD version of the S540 is an amazing package. The great display is a very positive surprise.
