Hello,
You never want to solder the 2 point together. That would cause havoc on your mobo.
You need to get the mobo specifications or blueprint to find out what Resister, cao or part went there. Then get the same exact part. It is a Surface Mount item at that. Which is tougher to solder on correctly cause of the small connection points.
Best course of action. Call Dell. See if you can get something worked out with them. Or take the suggestions above and try to find a replacement.
Cheers,
Mak
