A client brought me a black Powerbook G3 which I believe is a Pismo because of the bronze keyboard and reset switch near the modem jack. It does not power up at all and the green led doesn't even turn on. I have tried several different batteries and ac adapters (all of which worked on other powerbooks) so I have narrowed it down to the laptop itself.
I have tried all combinations of power adapters and batteries in and out with no change in behavior.
The power jack itself is not loose and when I plug the power cable in and put my hear close to the keyboard I can hear a very high pitched whine that goes away if I pull the plug out.
I have reseated the daughter card (no change).
I suspect the PRAM battery, but am unable to verify whether this no-start condition (you'd think the led would light up), is sympotmatic of this. I'm hoping I can find a PRAM battery locally.
Any suggestions? I'm a hardware gut so dissassembling it further to repair it (if parts are reasonable $$) doesn't phase me, but I'd like to make sure I'm barking up the wrong tree before I break out the tools.
