Ibook G4 won't start after shut down

[Cox Orange]

I was typing in a rtf document and it suddenly freezed when I put the blinking bar that indicates where the next letter will go in another location of the text. The mouse cursor was the blinking bar at the moment and couldn't be moved anymore. No beach ball. The Monitor picture just freezed.

Short cut that shows wether there is a hanging process that can be forced to cancel didn't work either.

i closed the lid, because it would usually shut down immediately, after one second of sleep and one short sleep light flashing (the sleep state doesn't work anymore since a long time ago). But this time it stayed on.

I decided to pull the power cord and take out the battery. Unorthodox "Shut down" successful.

I then put everything together again. Pressed the power button, but nothing. No power, no boot or whatsoever.
The green/orange light on the power cord and the four green lights on the battery are shining though.

I also tried out taking out the RAM.

Any ideas?

I guess I will open it and get out the HDD to get the text I was working on and need to send in time, what a pain in the butt!
I hope I haven't lost my upgraded beloved ibook 12" mid 2005 forever now. 😭

Have you tried starting it without the battery - only with power supply?

Do you get a boot chime at all? Sounds like a power problem then.

I am not sure, but now I tried again.
I hear a short sound as if a belt is rolling on (I guess the hard drive's spindle motor?) and then nothing. Also, a small green light next to the speaker max key in the middle of the Keyboard is on. But then nothing.

I don't know if it's a far cry but can you hook up an external display and mouse/keyboard?
Maybe the iBook thinks that the lid is still closed for some reason?

Tried a PRAM reset?
Can you get into Open Firmware? If so, you can try reset-nvram, set-defaults, reset-all.

I have a mid-2005 12” iBook G4 that basically did the same kind of thing; Randomly locked up, tried replacing RAM, HDD, disconnected Airport/BT daughter card, but no luck so concluded it was GPU / logic board failure.
