Capacitor Reference - PowerBook 100
Any PowerBook 100 must be fully recapped.
The display capacitors on this model are frequently replaced with ceramic capacitors. These may work, but have been shown to result in drifting contrast on certain LCD displays. This is caused by ceramic capacitors' characteristic where the capacitance varies based on voltage load. As such, I would recommend replacing them with tantalum caps instead.
The PowerBook 100's logic board uses a varnish that becomes sticky when exposed to Isopropyl alcohol. Keep this in mind during cleaning. To avoid this issue, you can get all of the varnish off with a LOT of IPA, or use a different method to clean the board. You could also just leave it sticky, but that does make working on it rather frustrating. Remember to clean off the cap goo via some method though! IPA will work, it just makes things a pain.
