You need to be aware of this if purchasing a Zenbook. Cracking issues with screen. It appears like impact damage but this laptop has had no impact whatsoever. Doing a search of the internet and others have experienced similar problems with the Zenbook. Cracks seem to initiated at the edge of screen or camera, probably due to screen being really slender so any temperature changes will cause high stresses at the edge potentially resulting in cracks initiating creating weakness and this eventually expands across the screen as in the case here. One minute it is sitting on the desk fine and next time I go to it 5mins later there is a crack. This is now expanded across the screen. This laptop was little over 6months old and this is the result. And now there seems to be charging problems too. This is not good enough.Further do not purchase appliances from John Lewis & Partners as they will fob you off with arrogance and incompetence in after sells service. First line of attack they say it must be damage and accuse you of lying. They have become like the Curry’s of this world, focused on the sell and commission and don’t want to know.
