It's been working fine up until now. It seems that if I fool around with it for long enough I do manage to get it to work, but then when I try to plug it in after taking it out, it doesn't work. Does anyone have any ideas? I've also noticed that the plug falls out of the back of the laptop with only a slight movement... Is it supposed to be that loose? I'm no longer under warranty and this is my second adapter from Dell... I really hate to pay almost $70 for a new one.
