:rolleyes: once again... POWERBOOK G4 STARTUP PROBLEMS!
I shut it down last night and tried to turn it on today, but to no avail.
The only signs of life I get is the hard drive quitely hums when I start it up and the green caps lock light works.
I get no chime, no screen activity and as far as I can hear with my ear pressed up to the case, no hard drive activity except for the platter spinning. (no clicks or ticks)
In an attempt to fix this problem i have performed the following steps
-reset power PRAM, and NVRAM
-reset Power manager
-disconnected all usb/firewire/ext devices
-tried starting in target disk mode
-tried booting from CD.
help me obi-won, you're my only hope.

If it doesn't pass the POS test, power on self test (piece of test)... startup chime indicates passed, it looks like you have some logic board problems.

Other than the logic board, what could it be and how do I determine what it is?

seems to be a reliable source as well. I'm thinking of upgrading my harddrive with them.
