When I go into suspend mode the whole computer shuts down except the power supply and cooling fan on the side of my case. I was thinking it's maybe a jumper problem on the motherboard? ASUS A7N266-VM mb with Win 2k.

Well, as far as I know, the PSU has to stay on in either Standbye or Suspend because the system state is saved to RAM. The PSU will turn off if the machine is put into hibernate mode (in WinXP, if that's what you're running) because it saves the system state to the HD.

AcidWarp is right. As for the fan on the side of your case the only way that will shut off is if it is directly connected to the motherboard. Most often those fans use the 4 pin molex connectors that duplicate the connector and run directly to the PS. If your mobo has a 3-pin fan connector and your PS has a connector for the mobo than you could reroute it and that would make it shut off during standby.

See the thing that gets me is on my Win 98 computer if I suspend, everything, ps and all, is shut down. I thought ACPI suspend to ram was supposed to put all ram data onto your harddisk, and cut the power to everything. I do see what you are saying about the fan, still confused about the ps.

when my XP used to be able to suspend (it hangs now if i try it), it would shut everything down. Suspend only provides power to the ram chips so they can remember everything. Thus, during suspend, your ram modules are fully powered, while everything else has been turned off. for hibernation, the current state is saved onto the hard disk

I think you may be thinking of Hibernate which does completely shut your computer down and save your Ram to the HDD.

I had no problem with the standby turning off all fans until I bought a logitech cordless optical mouse and plugged it in my USB port. Now when in standby, the fan won't shut off. I downloaded the latest drivers off their WEB site.
