PC Goes to Sleep when idle and will not wake up ..
The PC works fine when active, if for example I run a defrag or virus scan, no problems, it runs to completion.
However if I just leave the PC active with nothing running after about 20 minutes it goes to sleep, when this happens I hear some activity on the HD but that might be coincidental.
The power scheme is set off, therefore it is probably nothing to do with hibernation or sleep mode.
When I say it goes to sleep nothing unusual happens until I select sometning on the screen with the Mouse, eg. open a folder. Then I just get the egg-timer and nothing else .. Unless I reboot.
I have changed have flashed the BIOS just in case its an acpi problem, but that made no difference.
Thanks.

The fix seemed to be to delete hardware profiles and create new one.

Ok, tried both of the above, but no use.
I have noticed something else. When I remove the case to the PC there are four wires with single connectors . which are not connected. These are from the power switch, I think they are only for the speaker and the lights , could these effect the wakeup capability in any way ?
