Did it have the battery at all?
No battery.
first: hook up the voltmeter to the 74xxxx chip for
5v and ground.
I'm reading around 3.2V, which would make sense for a laptop.
second: hook up that power jack with right size
coaxial plug and to
veriable regulated power supply at least 600mA limited
My variable regulated supply is in my other suit (I really do have one,
just not here), so I used a bunch of different wall warts instead (center-
negative isn't nearly as popular as center-postive, it seems).
third: start at 6V and chank up in 1V steps until it
starts to work
properly especially for the display's crisp startup lamps.
Well, the good news is that there's no smoke. But I'm not getting any
lights either. I'll try to find a real power supply tomorrow and try
again.
Thanks for the help. My diagnostic skills are now floating above zero
thanks to you guys.
