Hi there,
I have two Powerbook 100s. My plan is to make one really good one out of these two old beauties.
I recapped one of them but it won't boot off my rebuilt battery. I have been suspicious of the appearance of the DC power socket for some time and then today while browsing online looking for info I noticed that my recapped logic board seems to be literally missing a piece. Please see the two images below of the complete and incomplete power socket assemblies: I opened up my non-recapped PB100 (left) and saw very clearly what was missing from the recapped PB100 (right). I'm hoping someone will be able to enlighten me as to what this missing piece is. At a guess after a bit of googling, could it be a multi-layer ceramic capacitor? Is this some kind of bridge circuit or something?
It is with considerable regret that I realised once I looked at these side-by-side that the little brown component from the plug on the right was sitting on my desk for some months waiting for me to work out where it had come from before I swept it into the bin.
The weird thing is that the powerbook with the missing component works very well running off mains - it doesn't run off battery though, and this may be connected. I have posted about my attempts to rebuild the battery in the powerbook 100 battery rebuild thread.
Edit: updated theory as to what the component is after some googling
