Hi, Today, I just got a free iMac G3. However, it is broken, it doesn't power on at all. This is an orange slot-loading G3, specs unknown. What I noticed, is that when I push the power button, the display makes a short buzzing sound, similar to when you touch an old CRT TV, just very short. No fans spinning, no hard disk sound, nothing. I really want to repair this mac, since this is why I accepted to get it free. My guess is that it's either the PRAM battery, SMC/PMU (or whatever it's called) or less likely the power supply (because the computer stopped working over time, not while using it). Thanks for all advice.
