AC power off
Inspiron 3671
I have a technical question. Well, I have a dell inspiron 3671 computer and every time before I turn on the power button on the housing, and just start the power supply from the power strip, for a moment before starting the computer with the power button on the housing there is a "start" of the computer for a moment, and then turns off. Of course, nothing disturbing happens during this procedure. Just when I turn on the power strip before starting the computer, it will start for a moment and that's it, and then I can start it normally. Can I disable this behavior in bios or is it better not to touch it?

Maybe I could word it a bit better but I think you got the answer to your technical question. When you are using a power strip (or surge protector), keep the power strip always on even when the computer is shutdown. Because your computer still needs a small amount of power to run BIOS scheduled tasks and controlled features like wake on LAN, real-time clock.
In case of power outage or no power available, the computer will use power from the coin cell battery during shutdown state. However small, you may have stressed out your coin cell battery and may need to replace it soon.

It's a normal behavior in all Dell desktops. If you want to disable this behavior, you will need to keep the power strip always on. Else, the desktop detects a power loss and will initialize a system check when it see power reapply.

" Else, the desktop detects a power loss and will initialize a system check when it see power reapply." You could word it a bit better. The point is that if I turn it off and the power strip is not turned on, the computer will start by itself?

FWIW, I turn off the power strip used with my XPS 8930 after every shutdown. It's 3+ years since I got this system and no signs the battery is weak/failing.
If you want things easy, open BIOS setup and change the AC recovery option to Boot when recovering from a power loss. Save the change and exit setup. Turn the strip off after shutting down normally in Windows.
When you power the strip on, PC looks for the BIOS AC recovery setting and that's why you see it start up briefly. If that BIOS setting is "Do nothing", PC immediately shuts down again. If you change that setting to Boot, PC will automatically boot itself without you having to press its power button.
I have PC, monitor, speakers, printer all connected to the same strip. So just turning the strip on powers everything on at same time without having to press any other buttons. Just make sure the strip can handle the load of everything turning on at once....
