I have a Gateway laptop and it has completely died and will not turn on. I noticed that when it died the AC adapter was making a clicking noise so I figured I would replace the adapter to see if that was the problem. I have replaced it but the new one also makes the same clicking noise but only when plugged into the computer (as was the problem with the old one). I know the AC adapter is giving sufficient power but the computer is not taking it. Any suggestions as to what it could be or how I can fix it? Detailed directions on how to fix it would be appreciated as I am no computer whiz. Thanks in advance!
