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.

Don't they also act funny if the internal battery

to provide a substitute for that voltage. My memory is pretty fuzzy... it's
been a while since I've read anything or given any mindshare to a Mac
Portable. But I definitely remember they had some strange quirks in their
behavior.
Best,

If this is one of the original Mac Portables
(white, wedge-shaped, B&W
LCD
screen), have you disconnected the HD from the
motherboard?
The HDs on these machines just love to die, and when they do, they can
screw-up the whole machine. If you haven't already eliminated that
possibility, I'd do it before you run around replacing anything else. If
you can find the correct drive, you can make a cable to adapt it to the
portable - but you won't have the low-power feature of the original
drive.
It's been 15 years, but I went through one of those machines, back when.

the follow caps. C4, C5, C15 and C24.
Does anyone know what value those caps are?
Thanks,
