[QUOTE="torbenc, post: 890713, member: 116354"] Hi I just got my hands on a very cheap Power Mac G4 Dual 1.25ghz "mirror door" with 17" cinema display. There was no harddrive installed because the org. died. The ram wasen't installed, but I got 4x512mb and 1x1024mb modules. When I power on the machine, the harddrive I have put in, spins up, but there is no "startup sound" as I read there should be. The screen is all black with no response at all (I can power on the machine through the powerbutton on the screen) I have tried to pull out the battery in 10min, and made an PMU reset with no luck. The battery shows 3.6v when I test it - So it should be ok? I have tried several different RAM setups, how should I place the RAM in the slots? one in J20 and J21 ? And where should the system disk be placed? There is several IDE ports where I can put it. (just so I know these two things are ok) There is a little red diode lighting right next to the RAM slots, should it be red? Hope someone can help me, else I will have to sell the machine again (in parts) [/QUOTE]
