Dell desktops turn on automatically when plugged in

[JumBie]

I recently got my hand on a bunch of Dell Optiplex 7010's. While playing around with them I noticed that all of the computers turn on automatically when I plug the power cord into the power supply. Not sure exactly why this happens, but its rather annoying. Could there be a setting in the bios that's causing this to happen?

Yes, there should be a BIOS setting that tells the computer to either restart after a power loss or to stay shut down.

yes, F12 pressed on startup opens the bios - then its under Power Management -> Auto on time..when disabled it should stop it...mine are dell 3050s but it should be similar

I think that pretty much all modern PC's have a setting for this. It allows you to, for example, use the switch on a power strip to turn on the pc, if you'd rather use that, or if the switch on your case is having issues.

In other cases, there might be some software running that you want to keep up and running, even if the power goes out for a bit. Maybe even something as simple as a birdfeeder cam that you want to start up and be running again when the power is restored. You can turn this off in the BIOS.

Why is this annoying? Once you have it set up to use, won't you leave it always connected to the mains AC and then it will operate normally? I never disconnect my systems from mains AC, except unintentionally during a power outage, then for my fileserver in particular (remotely located in the basement) I'm glad to have it turn back on so I don't have to go down and manually press the power button.

IIRC back in the day I was having systems turned on by sending them a magic packet over the lan, but having them come back to same on/off state they were in after a power outage is effortless.

I've noticed that laptops which are constantly left plugged in seem to have shorter battery life, compared to those which are left unplugged. That's about the only reason I can think of.

Definitely check the settings others mentioned.

But lots of dell desktops DO turn on momentarily after plugging in. It's normal, and probably some initialization or check is being done. But it only stays on a short while, it doesn't actually boot up and run. If it does, that's almost for sure the bios setting.
