My PowerBook doesn't fully power on.
Hey guys, thanks for reading my question, this community is awesome and helped me out a lot, so i am gratefull that this platform exists! Now, i have a curse on my hands i think, i am the proud owner of my 4th powerbook g4 17 inch, a lil’ back story, i LOVE to tinker with laptops, especially apple ones, i fully restored a Pismo which involved heavy soldering, heck, i even changed the CFL backlight tube in the display because this gave the screen a red, when warmed up a pink, hue on the backlight that would not go away, i even replaced the cells in the main AND the pram battery, i know how to solder because my dad taught me when i was a kid and been practicing ever since. This powerbook pismo just came out perfect, it works perfectly fine! But who knows the movie Gone In 60 Seconds? Well, i have my own Eleanor, its not a car, its this 17 inch powerbook! Yesterday, i received a diamond in very rough shape, it was dented and scratched like crazy, the screen broke away from the chassis, but other than that, the hard drive, mobo and optical drive are working perfectly fine, since this is my 4th try in rejuvenating a 17 inch laptop to my collection, yeah, i gave this already 3 tries, but i blew 3 of em up because of oversights, now, yesterday, i had this model (1ghz one), i finished putting it together, and everything finally worked, it booted up, gave me the flashing folder with questionmark and everything, it was ready for an os install, so, i installed a known good battery from one of my dead examples in it, it worked fine for about 2 minutes, than it had horrible clicking sounds like something was shorting out or something, i checked everything inside the laptop, and i could not see anything obvious, so i plugged it back in and noticed that the coil next to the ram is the culprit, it whines and clicks, the laptop powers up, i can hear the hard drive spin up, but no dvd drive sounds, boing or screen activity. So i am left stunned in what the problem could be, i mean, the battery is actually a new old stock which can keep a 17 inch going for 4 and half houres! Anybody has experience in this problem??
