Dual G5 running Tiger does not go to sleep

[fundikali]

Hi,
When the computer goes to sleep either by the user selecting the sleep
option from the menu or by machine inactivity, it only remains in sleep mode
for about a minute before powering up both the machine & display.

Computer: Dual G5, OS 10.4.1 (Fresh install), 30 inch Apple display, Apple
keyboard & mouse.

Thanks for your help,
Navraj.

Does anyone have any idea what could be wrong with this machine.
I failed to mention that we had upgraded the graphics card to support
the 30 inch display. Could this have something to do with it?
Card: Nvidia GeForce 6800

thanks for your help.

Bob,
It turns out that when the printer is switched on it cannot go to sleep. Strange?

Thanks for your post.

A lot of USB devices cause instability when it comes to sleep and power on/off. It's usually relegated to USB hubs and sub-standard USB devices, but any USB device can be a culprit. When encountering power on/off and sleep issues, USB devices are the first place I look.

Glad you found a solution!
