My area 51m has now stopped working at all. It will not take power from the mains power bricks, it will charge the battery and all I smell is burned ic and PCB. It is the worst build quality I've have see in 20 years of buying laptops and computers. With a laptop that cost as much as area 51m, I would hope to get 5 years of and not 12 -18 months of use it money down the drain.
