    The dc-in jack on my system76 lemur laptop has broken, and I'm trying to find the part number so I can solder in a new one. So far system76 are not giving up any details. However I'm pretty sure that the lemur is more or less a rebranded Clevo N240JU.

    Anyone have any advice on this and generally how to get info on parts for home repair / upgrade from resellers?

    Thanks muchly for any tips.

    It's 'WTJ-020-71C', according to the service manual. Finding an exact match may be difficult, since there are tons of slightly different jacks. The manufacturer's site might help in finding a substitute part; DC jacks.

    Resellers won't be able to help you unless they happen to have a defective motherboard lying around. Their repair shop would simply swap the defective component, dropping in a new mb.

    Soldering these things is a bit of a chore, mind. The power leads going into the motherboard are the widest on board, so there's a lot of copper to heat up before the solder will give way. If it's a multi-lead model then heating all of them at once is pretty much a necessity, so a hot air station would be useful.

    If it's just a case of a single broken pin then don't bother swapping the jack and simple resolder the joint; rinse the solder areas thoroughly with pcb cleaner, add some flux and drape the solder all around the broken connection. That should be alright for a good while and can be done with any regular iron.

    Unless you want to go hot wiring a plug in on a cable @t456 pretty much covered it.
