I recently replaced a DC jack in a laptop and when I reassembled it everything seemed to be working fine then it would shut off on me. I dissembled it to see if I had made an error on the reassembly, but could find no problems. I reassembled it enough that it would turn on and it did with no problems or random shut downs. After a few hours of running I had noticed that it shut off and would not power back on. I removed all the screws from the bottom of the laptop and sure enough it fired back up. My question is does this sound like a ground issue? Why would the laptop not work when the screws are screwed in? I rechecked my solder work on the port and everything seems fine. Should I just leave the screws out and run it like that?

Are the screws the same exact ones that held the original jack? If not, maybe the new screws are longer and bottoming out on something.

Have you used the AC adapter since the replacement? I have read that some laptop adapters have reverse polarity. What I mean is that the outer side of the connector is Positive and the center is Negative. Why in the world they would do that is beyond me but that is what I have read.

Yeah all the screws are original and there is none by the DC jack. Yes I am using the same adapter, and I also tried a universal adapter. Thanks for the help so far.

The screws must be deflecting something.
