So I got a pretty weird problem on my hands right now. I have ASUS N56D laptop with the original charger. I have had problems with the charger before, like when I want to charge my laptop, I need to connect the charger to my laptop before I plug the charger in the wall or else it won't begin charging at all. I have to do this every time I start up my laptop. Yesterday however was different. When I stopped working on my laptop, I shut it down and it kept charging the battery like always. I went to sleep just to wake up in moderately loud ''popping'' noises that came out of my charger. I disconnected it from wall. Well today I tried to charge it again and when battery reached 100%, followed by the same noise, it blew the fuse. Tried again to charge it to 100% on different socket and it ''popped'' again, not blowing the fuse as I was fast to disconnect it. My sockets are not grounded in this new house I just moved in but I can't comprehend if this is a problem with the battery or the charger trying to discharge itself in the socket or something... Help is needed indeed.
