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.

  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.
