Q: Resetting SMU PRAM & NVRAM iMac G4 Flat Pannel
I posted another ? in a different forum but have not received any help so far. I've been reading about different potential 'fixes' to issues which I seem to be having with my iMac G4 Flat Pannel.
Some background info:
My computer froze up and I could not get it to respond with keyboard commands and it would not restart or shut down when I held the back button down either. I decided to cut the power on the power strip, and when I restarted my computer, I heard the fan come on, but my screen was completely black. There was no 'power on' light on the monitor this time either and the computer no longer responds to the keyboard and my mouse no longer lights up..
I'm hoping someone can help with some questions I have after having read about resetting various buttons..
First, will resetting the PRAM result in loss of any data on my computer?
Second, do G4 iMacs have a SMU reset button, or is this only on G5 models?
Third, will resetting the NVRAM result in a loss of my data?
Lastly, does anyone else have any suggestions to help fix my problem; does it look like my computer is dead?
Thank you for any help! =) *april

Ok, resetting the PMU is the last resort. If that doesn't bring your Mac back to life there's something seriously wrong.
If really nothing happens when you power it up, you will not even have a chance to boot into the Hardware-Test CD/DVD that came with your Mac.
Did you install more RAM? If yes, remove it and try again.
If not you can't do anything more and have to take it to an authorized Service Provider.
