As your fan spins you do have power. Also, you don't say if the HD spins up or not. Also, if you get more life into it but you still can't boot, you can try and boot into Open Firmware by holding Cmd-Opt-O-F and typing "set-defaults" + <return> + "reset-all" + <return>. Then try and boot from CD by holding down key "c" My best advice, leave it plugged in for a couple of days. That have helped many seemingly dead machines. After that, remove one RAM chip at a time, replace with known good. As for getting to the PRAM backup battery you need to (after you have grounded yourself) remove the: � AC adapter � Expansion bay modules � Keyboard � Heat sink (after this you can touch the cage as an alternative way to grounding, but this means you should actually leave the power supply in and be connected to a grounded outlet via power supply with a ground cable. Better to just get a grounding wriststrap.) � Clutch cover (careful as not break the plastics) � Display (be very careful with the cables) � Hard drive � Modem or modem plug � Microprocessor board top case � Top Case on the underside you'll find the PRAM backup battery connected to the PMU board. I do wonder if unplugging the PMU card could potentially have the same effect as unplugging the PRAM battery. I'm not sure.
