Laptop works on AC only with external monitor


I replaced the DC jack on a gateway MA7, real simple process.

Now the AC power seem to only work with an external monitor plugged in to the back. As soon as I disconnect the monitor the laptop switches to battery power.

I pulled the battery out and hit the power button and nothing. I then connected the external monitor with the battery still out and it turns on with no problem. I then pulled the power jack out and the laptop dies.

So the laptop will work on AC with out the battery as long as a external monitor is hooked up.

Any thoughts, Hints or Tips?

  1. Must be something in the hardware, open it back up and make sure there arent any shorts or anything connected to the wrong place near the DC jack, it sounds like something didnt quite go as planned during the replacement.
