It depends on the model and the style of plug mounted on the system board. If it's on the system board, it would have to be re-soldered, or soldered off and and a new one put on. Finding a board mounted plug that fits and works can sometimes be difficult. Anything else is easier, if it's a separate part or on a separate assembly board. Easiest way to tell, is an estimate, or info from the internet. Or look up the parts and disassembly manual on line at DELL. Some places will say system board has to be replaced. Sometimes requires gutting the part from another dead board. Other people will solder in an extension pigtail for the plug. So I guess it varies a lot, but it can be done on the cheap if it has to. DELL Inspiron 1150 Manuals I looked at the manual, and it appears to be one of the "little metal box" type connectors, on the system board. It's a bit hard to tell looking at the grainy pictures in the manual. I've not had much luck finding replacements for those.
