Capacitor Reference - PowerBook 160
The PowerBook 160 has no electrolytic capacitors on the logic board. This means that the only caps you will have to replace will be those on the Display, and optionally, those on the Inverter and Trackball boards. The latter two are not a 100% must do, but can, and in the case of the inverter caps (or just cap, there is only one electolytic present), have been known to fail. Failing inverter board caps can introduce inconsistent backlight/contrast behavior even after the LCD itself has been recapped. The LCD uses surface-mount caps and is a must-recap.
The display capacitors 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.
