FC4 machine with Asus A7n8x-E Deluxe system with Athlon XP 2600+. After a while (no pattern yet), that machine goes into what seems to be some sort of wierd power saving mode. The following lights are on:
1) Power light
2) Motherboard power light
3) Gigabit network adapter (built into motherboard) both link and activity on solid.

The hard drives are off as are the case fans and that power supply fans.

The reset button does nothing. Pressing and holding the power button causes the power light to turn off. Then the machine can be restarted by pushing the power button again.


Any ideas what would be causing this? Or where I would look for what's causing this?


Thanks in Advance.

Is powersaving enabled in BIOS? You could try disabling that. You could also try changing the power saving settings from inside Linux (these are independent of the BIOS settings as far as I know), in KDE this can be done via System Settings/Control Panel. Not sure where it is in Gnome.
