Bought this as an Emergency backup in case something were to happen to my new one like say a direct lighting or meteor strike or perhaps someone's bratty kid pouring soda all over their neighbors laptop for some inexplicable reason.....again. Well anyway I was setting it up today so a visiting cousin could use it and it does not work, the lights come on and the fan spins and it gives a weird buzzing beep. Monitor is good tho. Unfortunately I either forgot to see if it worked when it arrived or I did and it doesn't work now that it is too late to do anything about it.
