PowerBook 2400 Power/IO board capacitors

[Elemenoh]

The PowerBook 2400 uses tantalum caps on it's motherboard but has some atypical (for Apple) through-hole electrolytic caps on its power/IO board.

Location	Capacitance	Voltage Rating	Diameter	Height	Temp Rating
C39	100uF	10V	10mm	6mm	105º
C48	100uF	10V	10mm	6mm	105º
C47	150uF	6.3V	10mm	6mm	105º
C38	220uF	10V	10mm	10.5mm	105º
C46	330uF	6.3V	10mm	10.5mm	105º
C26	10uF	30V	8mm	10.5mm	105º
C15	33uF	25V	10mm	10.5mm	105º
C25	10uF	30V	8mm	10.5mm	105º

Curious, has anyone brought a "dead" 2400c back to life by recapping its power/IO board?

Ah, those aren’t electrolytic caps. They’re Sanyo OS-CON caps which are solid polymer and won’t leak/are very unlikely to fail. Still good to have the values just in case but the chance of one of those failing is next to none.

Oh interesting. Saw cans and assumed electrolytic. Thanks for the correction.

If you see that purple, you’re usually safe

Would be interested to know if there are any caps on the LCD or its inverter board. And the model number of the LCD.
