PMac 8500 is a doorstop!

As I stare at my Power Mac 8500 Nitro DOORSTOP I decided to see if I could get it working. I booted it up and....NOTHING. I reset the system mainboard and NOTHING, I tried to boot from the cd-rom with a OS 8.5 CD and you guessed it ....NOTHING. Anyone out there know a bit more about macs than me, I've used them but never had to fix one. Any help would be most wellcome. :bigcry:

I'll have to get a new battery and try out the above. I did reset cuda and MB but considering how long this things been sitting around I reckon the battery would be dead by now. thanks so far folks, I'll post my results. :-D
