Recaping a Macintosh Portable

[Ben Sinclair]

I have a Portable as well, and that's correct about the battery. It won't
boot at all, even with external power, if the battery is dead.

Try doing some searching about alternative power supplies. I believe the
problem is that the standard power supply can't source enough power to get
things started on its own. I've read about people having success using a
power supply from a PowerBook 100, or building their own power supplies.
