i have a dell 600m with the powerjack on the motherboard broken out. i would like to try to solder the 3 wires from the end of the ac adapter directly to the MB, but cannot identify the correct connections from the broken jack to the pins on the MB. two of the solder spots on the MB are labeled #1 & #2. can anyone assist?

You can buy a new jack on ebay for a few quid and you could just email the seller and ask how its connected they would know
