I came into possession of a laptop with a blown out plug. It is an older dell inspiron 300m model. I was thinking that instead of purchasing a new plug, and power cable (which for this model I don't have), I could just use an old power cable from a different laptop (which meets the laptops voltage and amperage requirements) BUT, and this is the kicker, I would just wire it to the battery leads to supply the power avoiding the blown out plug. Would that work? Would I just need to identify the +/- connectors on the battery adapter and solder the cables onto them? Would the voltage requirements be different for the battery then for the main plug? I am including a bad picture of the connector, I will post a better one when I have the motherboard in front of me.
