Capacitor Reference - PowerBook 100
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.
Logic Board
- 1x 330uf 16v (Radial)
- 1x 220uf 25v (Radial)
- 3x 100uf 10v (Radial)
- 1x 47uf 35v (Radial)
- 5x 47uf 16v (Surface-Mount)
- 5x 10uf 16v (Surface-Mount)
- 1x 4.7uf 50v (Surface-Mount)
- 5x 1uf 50v (Surface-Mount)
CPU Board
- 1x 10uf 16v (Surface-Mount)
LCD (Sharp LM64P791)
- 8x 3.3uf 35v (Surface-Mount) - These caps are encased in plastic shells that makes them easy to mistake as tantalums - they aren't!
LCD Inverter Board
- 1x 47uf 16v (Radial)
- 1x 15uf 16v (Sanyo OS-CON Polymer - Radial. This cap will not leak, so replacing it is optional. It may go out of spec due to age, but will be far more reliable than an electrolytic)
Trackball Board
- 1x 0.22uf 50v (Radial)
- 1x 10uf 16v (Radial)
