Powerbook 100 working

[imactheknife]

So was able to pick up a local powerbook 100. Couldn’t believe it was local and really nice shape and cheap!. No power, dead. Psu dead. I have two new power supplies, but still dead. I removed all old caps i had replacements on hand for (47uf, 10uf, 1uf etc) cleaned board really well, clean pads really well, recapped what i could, let dry. The display hasnt been recapped yet. Fired it up, she works my other powerbook 100 logic board gives me the black screen with its display, and the new one, but this new board works fine with both displays. So yay, that was a good pickup. Also had the ram upgrade in it. Came with floppy drive as well

Why did it work and show a floppy icon, then now just black screen lit up.. has to be something easy

Will display the no contrast/black screen when the caps are dead. Likely one gave out, or another issue.
