The laptop looks like a Surface Pro at first glance, thanks to a unique hinge design, but isn’t like that Windows 10 tablet at all. > That interesting hinge is known as the ‘ErgoLift Hinge,’ and it raises the angle of the laptop base and therefore the keyboard when opening the laptop. This is because the hinge is positioned a bit above the edge of the laptop lid.
