Modern flat laptops with nano security slots will fit a regular cable lock, but the laptop itself is so thin that it won't lie flat when the lock is fitted as it is thicker than the laptop itself, so it will stand out from the surface it is resting on. The Slim NanoSaver® laptop combination lock is the strongest keyless... security solution that allows ultra-thin 2-in-1 laptops with nano security slots to lie flat and stable on a surface.
