Power Mac G4 sleep problem

Hello!

My G4 (mdd) won't go to sleep anymore. Neither on its own via energy saver nor when you press the power button or select sleep in the apple menu. Does anyone know what to do?
I already unplugged my USB devices, didn't help. Then I trashed my energy saver and bluetooth preferences and reset PRAM by pressing <command option+PR> at startup, no luck. I read all the previous posts about this issue and did everything they said, but it didn't help.
maybe someone has an additional suggestion.

Thank you!

David

Guys, please read the **ing thread before you post stuff!

It's not helpful if you post things double and triple!

Even a tech might not be able to figure this one out. A clean install on a reformatted drive should take the software-side back to being pure as possible, so this kind of points to hardware. Re-reading the thread, I didn't see any mention of a PMU reset or resetting the Open Firmware - have you tried these?

Hey thanks, I haven't tried PMU reset (I thought only laptops had these), or resetting open firmware. Although I would have thought an erase and install would take care of this.
Do you have any links or can you tell me how to do this?

Thanks a lot.

Hello!

I have a quick question which is related to this thread. I was having a problem with my G4 sleeping, which I sort of solved. I have a new USB2 card in my box with an iPod mini dock plugged into it. When the iPod is physically in the dock (mounted or not), the box won't sleep properly and basically locks up. The problem goes away when the iPod isn't in the dock.

So... Since it seems pretty clear that this is the problem, is there anything I can do to "fix" the situation so that my box will sleep with the iPod in it's dock?

Thanks,

Michael

I have the same issue with ipod/usb not sleeping and have asked on other topics for input.

As far as I know, it is a common problem/issue and not limited to our macs but like you, I would like to know for sure.

It's the same problem I have. When any device connected to the USB PCI card is drawing power (ie: charging iPod) the Mac tower can't properly go to sleep. I have to remove my iPod from the dock before initiating sleep or the tower hangs.

The PCI card doesn't support sleep when it's giving out power to devices, it's a common problem I've seen.
