Loud noise when I plug my laptop in

[chammy]

I have a Packard Bell EasyNote TJ68 with 4.00GB memory. It's a fairly old computer but I've had this problem since I got the computer and I've finally snapped. When I plug my laptop in to charge, it makes a very loud noise unless I have the speakers on mute. This wouldn't be a problem but my laptop power cable is slightly loosened so if I'm sitting with it on my lap and I'm listening to music, it's always make a horrible noise every time the cable dis or re-connects when I move. I can't for the life of me figure out how to disable this noise. I've gone into sound and power options, and switched everything I saw to mute and still nothing. Please help!

Probably a screaming capicator...
MBoard replacement would be the only way out...unless you pay a shop to disassemble it and replace the bad cap which more than likely would be more than a new board.

Sounds like your power cable connector on the computer has been damaged in a way that makes the cable feel "slightly loosened".  This clearly seems to indicate a faulty power connection/connector which causes the noise you hear.  I suggest you have a repair shop look at it.
