Hi, Technibblers,
I'm working on a laptop that, from all of the symptoms prior to failure, has a bad internal power jack. I've only done a few repairs of jacks, and all of those were obvious visible damage: the jack had worked loose from the board itself and needed to be cleaned or replaced, and re-soldered. This one, however, looks fine from the outside, and all of the solder points are solid. I think the center pin has worked its way loose inside and is no longer making good contact, or any contact at all. There's some slight play in the pin when I try to move it, but I wouldn't normally think it would be enough to make it lose contact, but I suppose it might be. The client's daughter had taken the power supply back to school, so I'm waiting for my own universal adapter to arrive in the mail to test it myself.
So, do the experts here think I'm correct, that the center electrode is the culprit here? Is there a good way to test this, other than with a working AC adapter? What percentage of jack failures do you see where this is the problem, vs. failure of the solder joints or something else?
Thanks!
