Problem with "New" iMac G4

[ryan5091]

Hello, this is my first post so i will sound a bit noobish,

on Friday, i got a iMac G4 with the 20-inch screen usb2.0, the powerpc 7450 clocked at 1.25 GHz, 1.5 GB ram and 80 gb hdd and dvd-rw

everything is fine with this machine and it runs great running leopard 10.5.8, but i have found one and one only problem, when it goes to sleep, the sleep indicator comes on, and when i wake it up from sleep, i hear the osx in the back ground, but only the screen backlight comes on. i have tried resetting the PMU, NVRAM, and PRAM but nothing worked. so it wont wake up


please help,

thanks
Ryan

What exactly do you mean by "hear OSX in the background?"

Volumer

I cash hear the noises when I press keys on the keyboard, and the volume noise when pressing volume up down or mute, thats what I mean

could it possibly be that there is an extra 512 mb of ram? meaning i got 1.5 gb, i saw on crucial that the max memory is only 1 gb? is that true? i could be looking at the wrong model on crucial, i got the 1.25 GHz g4 with the 20 inch screen tho

Your particular model of iMac can accept up to 2GB of ram, so I doubt that that's the problem.

I've heard of a similar problem to this that affects iBook G4's, there is a sensor near the optical drive and if it stops working, the system fails to wake from sleep mode forcing a hard reboot of the computer. It may very well be different on the iMac, not entirely sure.

You might just want to disable sleep mode by going to System Preferences> Energy Saver> and sliding the sleep time option all the way over to "Never"

There's no real problem with not letting your computer sleep, sure it'll draw more power, but just lower the brightness of the screen if you're going out for a while, and shut it off before you go to sleep, and you should be just fine.
