Why does my ATX PC power up when I turn on my surge protector? SOLVED!!

[Herkulese]

I built this new system (see my sig) on my work bench using a Surge Protector that has no On/Off switch. I just turn off the PC and Monitor and unplug it when I want it off, and plug it in when I want it on. I have been doing this for several builds over the past couple of years. All was going as it should, in that when I plugged in the Surge Protector, nothing would happen until I pushed the Power Button on the PC, at which time it would power up.

I moved this system from my work bench to my office and am now using my regular Surge Protector with an On/Off switch. Now when turn on the Surge Protector, the PC powers up spontaniously (without me pushing the Power Button).

Any thoughts as to why this would start to happen?

Bump,

Has anyone else experienced this, and if so, do you have any idea why?

I can't remember the exact name, but there is a setting in the bios about what to do after power loss (such as yanking the plug or power outage) and it has an option to resume power to the pc. I actually set mine like this on purpose so that I could just hit the button on my surge protector and have everything power up in one shot instead of turning everything on individually.

I don't know if this info helps you, but this was the first thing I thought of. I'm sure once you start fishing around the bios you'll find the setting that I'm talking about.

Thanks Cougar,

I will check this out.

BTW, I don't mind that it does this, I just want to know that it is supposed to and that I did not do something to damage the PS, BIOS, etc.........................

I should have known that it could have been a setting change, but I didn't think of this because it was not like this initially (out of the box). I have dumped the BIOS a couple of times, but I thought that it would always come back the way that started out.

On the other hand, this board recognized the floppy drive automatically as well, but after dumping the BIOS the second time, I had no floppy drive and, again, thought that I had broken someting. After a two hours of changing floppy cables and floppy drives, and simply going crazy, I found that it had just not auto-recognized the floppy drive after the last dump. I simply reset Floppy Drive A to 1.44 x 3.5 and viola there it was again. Go Figure.........

Then and only then could I upgrade the BIOS.

So I guess that the setting to Power up when switching on the Surge Protector could have changed as well, the new BIOS may also have changed this setting, although I wouldn't have thought that it would. Silly Me...............

I will check it out.

Thanks again,

We have some dell's here at work and some of them do the same thing. From the work we have done we found that if we had ACPI disabled in the bios the computer would never shutdown completely, (Just go the the "It's not safe to shutdown" screen, and then we would kill power, so when power was turned back on all the computers turned on as well. If we enabled ACPI in the bios the computer would do a complete power down when we shutdown windows, then when we kill power and turn it back on the computers would not turn on without us hitting the on/off switch on the computer. Just throwing some more of my experiences out there.

Cougar,

You were on the money. It was the Post Power Loss setting in BIOS/Power Mgmt (last item). It was set to "Auto", so I switched it to "Off" and now, when I turn on my Surge Protector the PC waits for me to hit the power button before it will power up.

Thank you very much for the suggestion.
