The 720S is only available in one screen size and sports a 14-inch full-HD (1080×1920 pixels) display and will be available with up to seventh-generation Core i7 processor. The laptop offers 512GB of SSD storage and comes with an impressive 16GB of RAM. Notably, in terms of connectivity, it provides a Thunderbolt 3 port. Lenovo’s new IdeaPad 720S weighs 1.55kg and is 15.9mm thick.

It also has NVIDIA GeForce 940MX graphics. Sure, that graphics card is a generation old at this point, but it should still provide substantially more GPU power than you’d get from the integrated Intel HD graphics alone.

The notebook has a Thunderbolt 3/USB Type-C port, two USB 3.0 ports, HDMI and headset jacks, and an SD card reader as well as a fingerprint sensor.

  1. The RAM shouldn’t be welded to the motherboard in this laptop.
    If you open metal shield (need to loosen the clips) you can remove the RAM chip then.

    Can you please confirm?

    • I agree with the fact RAM shouldn’t be welded to the motherboard in this laptop (there is a hardware maintenance manual that supports this) but seems to be impossible to remove the RAM shield, at least in my case (I own an 8GB RAM version). Can anyone confirm is RAM is upgradable into 720s-14IKB model please? Thanks, in advance.

      Chers from Argentina.
