Hello Forrest, Allen, Michael, and Newton Friends,

After a long afternoon and evening, I am happy to report that my eMate and I have survived the hinge repair effort!  The soldering work, while not terribly difficult, took me two tries to get the speaker and backlight wire pairs properly reconnected with the motherboard.    The end result is a working eMate with two new washers that are guarding against springs popping out of the hinges.

Thank you for sharing your technical procedures, insights, and encouragement to help me get this vital eMate repair done!

Here's a picture of my eMate after the repair:

    Spare CD/hard drives (etc.) work decently for practice.  You definitely
    don't want to try to reflow solder for the first time on something you
    don't want to potentially be (catastrophically) destroyed.  Soldering is
    not hard, but it requires some familiarity with techniques and temperatures.

    My first experiment likely destroyed the internal traces on an SE/30
    motherboard.  Luckily, the board was almost certainly dead to begin with,
    but it was an instrumental lesson.
