    I just found these. I had forgot that the usb on these are upright. It may be useful for the board members to know of a source.

    Mmmmmhmmm... It's VERY CLOSE, but not the exact part. 2 possible issues:

    1) Offset from PCB may be different in height and/or depth.

    2) It MAY NOT be wired the same; the USB port Panny uses has 2 of the leads reversed from the normal USB pinout. You can't tell from the pic how this one is wired. See here:

    And here:

    At least it's a possible part that someone with enough ambition could hack-solder into place; as you say, worst case scenario you nuke the MB and have to replace it anyways.

    I would take measurements with a caliper to ensure precise location of the port, then break the old port apart carefully with pliers & tin snips to get down to the bare leads. from there you can decide whether it's better to try and remove the old port, or trim the old leads to stubs and hack-solder to the stubs.

    Just be extra careful you get the pinout correct:

    or you could toast the USB controller and have to replace the MB anyways.

    Good find!

    Good luck!

    For some reason I didn't receive an E-mail notice of this post.

    Anyhow, $48. is more than I planned to invest in this laptop.

    I was hoping for something about half of that.

    Sure appreciate the link ... if that is the typical price then I will have to give this some more thought.

    I've sent an e-mail to the seller of that mbo. before and I asked if the ribbon connectors are all intact but there is no answer so far. Be very careful on just buying those type of mbo. without the full detail. You may end up getting more parts.

    I'd rather get one from someone here on this Forum - as folks here seem to be reliable.
