Power Bar turns on system?

Hello

My question has to do with my second system, using a MSI KT4V KT400 6712.

My issue is that when I turn on the Power Strip, the system turns on! This happens even before I even touch the Off-On/Reset button. Turning off the system all is just fine and there is no wake-up issues! All the usual wake-up goodies having to do with things like the Modem and Nic are turned off. Its just it turns ON all by itself the minute I switch on the Power strip/Utility power bar for the system.

The case for this system is a full tower with only one button. Usually this one button cases work at, with a quick hold on the button for reset, and a long 3-4 sec count for the system to power off. In the past this Motherboard setup worked great without an issue on my other Mid-Tower case. This other case used the usual two button Power & Reset buttons.

Once upon a time I had the fix for this! I just can’t remember what it was? I had to do something like, not connect the Reset cable or something from the case to the mother board or switch something off/on in the BIOS? I just can’t remember! The case wiring has the usual Power Led, Power Switch, HDD Led, Reset Switch, Power Led and Speaker.

Any Suggestions?
I mean what am I missing here?
Thanks for your time.

On your mobo, "Power Button Function" and "After AC Power Loss" are set to On/Off and Power Off, respectively, correct? And holding the power button for roughly 5 seconds doesn't do the trick?

Try turning off the power strip, holding the power button for 5-10 seconds, then turn on the power strip, and finally press the button. I would suggest a CMOS reset if that doesn't work. As you may or may not know, this incident occurs because of a power failure or an interrupt. Do you remember if the system was in motion while the power strip was on and/or the system was on and thus causing a ground fault? If you haven't already, inspect the psw wire.
