Capacitor Reference - PowerBook 520

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.
