hi!, this is my first post and i really need your help, some days ago i bought from internet a pb1400 almost mind but it say "doesn't turn on" on the place, anyway.. just for $30 bucks... the PB came with a real damaged battery charger.. the cable even wasn't attached to the charger... anyway...
i cut of the cable and send 12 volts (i know that this model is for 24volts). the Sleep light turns on... y pressed the power key on the keyboard and nothng happened... i press the power button on the back and the light stop glowing but tunrs on again... i unplug the mac... and the light was still lit.. was getting power from the pram battery... what sholud i do... i take it apart... there was a giant blow up in the mobo... even was a hole throught the PCB... and there was two fried IC (some 8 legs Fet chips) and also was some sort of bridge made out with telephone wire... really wierd...
so i decide to replace the fet chips... just replace one.. i tested and... CHNNNNNNNNNNN, display backlight flash for a micro second, i heard the satartup chime..., the hdd will not spin up.. the keyboard doesn't respond... and some second berfore... i heard on the speaker that makes a Plup plaf pluck noise and shuts off... pressing te PMU button only makes the pluck plaf plum noise...until i reset the power manager... but start and run for some seconds and dies....
what do you people say that i should make? throw it away is not an option... i love apples and where i live (argentina) are very hard to get... any help is appreciated, thanks for your time!
