PowerBook G4 motherboard question

Attempting to resurrect dead 1 GHz DVI PowerBook motherboard.



What are the minimum components required to be connected for the motherboard to show signs of life?



I currently have these connected:



- power-in connector & pcb



- power button



- 3.6v backup battery pcb



- headphones (to hear the boot gong or error beeps)



What else:



- keyboard?



- hard disk?



All I'm looking for is a boot gong or error beep code.



Also looking for group, mail list, or other forum that has the greatest wealth of PowerBook hardware repair discussion. Suggestions welcome.



Thanks,

I don't know the exact answer but suspect most things have to be present except for the HD ( at least older Macs would happily gong & then show a disk with a ? in it if no system was found).

Get the manual through Gamba's site,

You're in ds-country it looks like, dead mobos are not easily diagnosed without specialised equipment. Maybe you can establish voltages on the various rails (+/- 5V, +/- 12 V, whatever the Mac uses on the board).

I assume you verified the power adapter works..?? You don't need a battery with the adapter.

Good luck,

Mac Dude
