My 17 yr old son who doesn't look after his things, claimed he needed a new laptop after this one had just been repaired a few months ago. The laptop is still only 18 mths old. He reluctantly agreed that it could only now be the mains charger that was faulty so this seemed a relatively cheap punt compared to the new laptop. The product arrived and have heard nothing more since. I think this means it works without caveat, so everyone happy.
