hi folks, im hoping you may be able to help me bring a g4 powerbook(aluminum) back to life. i recently purchased this as semi-working, and am attempting to fix. the lowdown:
-i installed a brand new WD hard drive. NO OS installed on it.
-reseated the cd/dvd drive. seems to work properly, in that it accepts a disc.
-reseated the internal battery.
-battery doesnt hold charge at all, but power supply lights up, and seems to work properly.
here's the problem: it doesnt boot at ALL. upon powering, the drive spins, but i get no screen images at all. also, it will not do the "auto power down" thing if if hold the power button down; i need to unplug the PSU to power it down(i can hear the HD spinning, or at least the comp doing something)have tried:
-booting in safe mode(didnt expect this to work without a HD w/ an OS on it, but still...)
-booting from disc.
-booting from disc with all combinations of the internal HD and battery disconnected.
any ideas how to further diagnose? i was told that it definitely did not have any water damage at a point. thanks for the help.
