Capacitor Reference - PowerBook Duo 210
The Duo 210 must be fully recapped. Running one on original caps introduces a high risk of the cap goo causing a short circuit, leading to the logic board being permanently destroyed.
Do not replace the LCD caps with ceramic capacitors. They 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.

Trackball
Earlier revisions of the Duo trackball have a single leaky cap on them - one of those "impostor tantalum" caps that's actually an electrolytic. The later revisions use a 22uf 10v tantalum cap instead.
