do not use any charger other then the 1.5a Macintosh portable charger. The portable is not equipped to handle the extra current you will overheat your battery and you will burn out your 12v boost regulator.
do not run a portable with out a working battery. think of the portable as a LED, IF you use an adaptor with more current make sure you insert a resistor to limit the current to 1.5a it's depressing when i do portable re-cap's and the regulators are all burnt out. Because that means a re-cap is not going to fix it, depressing for me and for the customer. Ps: why would there apple of even thought to design the board to handle more current then 1.5 amps? At that time none of those other powerbooks had been invented yet! Think About it.
