Re: Replacing Laptop Power Jack
The power jack connector or the power brick? It should be no problem to replace the power brick, just buy a new one that is compatible with your laptop or a third party one if Dell no longer makes the one you need.
If you need to replace the connector, however, you will have to take your laptop case apart and remove the motherboard. You'll then need to find a replacement connector and desolder the old one from the board and solder the new one on. This wouldn't be too hard, but finding the part is an issue, and the solder used on high performance electronics equipment is usually very high temperature and is hard to melt.
