Leave USB without light when the PC is turned off

[QVENGADOR]

Hello everyone:

I have an old PC with the Gigabyte 8I945PE motherboard that I would like to turn off the USB connectors because I have it connected to a power strip that when the PC turns off, it turns off other items I have on the strip. The thing is that it is disconnected with the wake lan and other items and the USBs do not turn off and it's driving me crazy
I just want to know if it is possible to remove the power from the USB connectors.

Hello,

I don't understand at all what you're proposing. I don't know if your PC turns off things around it by itself, if the power strip turns off the PC when you tell it to, or if neither of these things happens and elements turn off or stay on randomly on their own.

Trying to dissect your opaque message, I can tell you that if you want to cut off ALL the power to the PC (including USB ports) you can turn off the power strip you mentioned or disconnect/turn off your PC's power supply.

Although I have the slight impression that you already know this and it's not what you're asking... I recommend you post some photos or something minimally indicative, because I think you haven't managed to explain yourself clearly enough. That or my understanding is greatly limited.

Sorry for not explaining myself properly.
I have a power strip with several sockets which has a USB connection to the PC so that when you turn off the PC, all the sockets on the strip turn off. This works as long as the USB port on the PC does not light up. I mean that if the USB port, even if the PC is off, continues to light up, the strip stays on, which means that it does not turn off the router, the scanner, the printer,…
What I want to know is if it is possible that when I turn off the PC, the USB ports do not light up…
So as not to waste your time, I will tell you that I have disabled the following items from the motherboard:

• USB Device Wake-Up From S3
• Soft-Off by PWR-BTTN
• PME Event Wake Up
• Power On by Ring
• Resume by Alarm

The motherboard has an award BIOS CMOS Setup Utility-Copyright (C) 1984-2005 Award Software
and I am not telling you what the motherboard is because I don't want to waste your time looking it up and looking at its components. Every time I come in and ask something, I always make you waste your time. I just want you to give me some idea to continue investigating myself.
Well and thank you for your time….

Hello again, don't worry about the time, because if it's well invested and we all learn, it will never be wasted. Besides, you already put the motherboard in the first message, we have that data.

Now I understand what's happening to you. You have a USB strip but only for power, not a HUB. Honestly, I've never seen a device like the one you mentioned, so I insist that it wouldn't be bad if you could illustrate us with a picture, since I can't find any on the internet.

You say that when you turn off the PC, the rest of the peripherals that said strip powers should disconnect, but according to what you say, it doesn't happen and they stay on. I think that no matter how much you disable parameters in the BIOS, nothing will work for your purpose, since except for the date and time, all the information is used exclusively when the computer is running. I know it's not the solution you're looking for, but until you show us a picture of the mysterious strip, I think you'll have no choice but to turn off the PC's power supply.

The power strip is of this type

As you can see it has a USB cable that goes to the PC. Then the first cable is the one that goes to the PC, the latter always has current. The rest of the sockets only have current when the PC is turned on. The power strip finds out that it has to give light to the rest of the sockets because the USB cable that goes to the PC communicates it to it. But now this no longer works since when it receives current in the USB, the rest of the sockets are always on.

About the name, the motherboard, what a mess, I didn't remember that I had put it at the beginning :wall:
The thing is that I used this PC as a server to test web work, which is what I dedicate myself to. I tell it to do things and I leave it alone. But when it finished, the PC would turn off and, at the same time with the power strip, the rest of the accessories. Now with this PC that always powers its USBs, it no longer does that to me.

I'm starting to get quite intrigued with this power strip and USB thing

In my opinion, the motherboard is too old to be able to control the power supply of its USB ports, as we do in more modern motherboards, which allow devices to charge on the USB ports without the computer being on.

On the other hand, I haven't seen any power strip yet that is controlled by USB, as it seems you say it can be done with yours

To simplify, I understand that if the power strip turns on when it has power through USB, but that power comes from a computer that is connected to the power strip itself, it will be like a fish biting its own tail. As long as you don't turn off the computer, the USB won't turn off, nor will the power supply in the power strip (unless you do it directly).

In the BIOS of your motherboard, you will have little more than the option to enable or disable USB 2.0 compatibility and USB Legacy (try disabling it), so things are not very clear to meddle with.

Cheers!

As already pointed out, the problem is that the motherboard does not have the function to disconnect the USB power when it turns off, which prevents the power strip from turning off. :wall:

You can "manufacture" a USB connector that does not depend on the USBs of the motherboard. ;D
Knowing how much voltage the relay of the power strip requires (5v), we can derive from the 3.5" floppy disk connector (the BERG) or simply a MOLEX, and take the signal from there
(connect red**-**red for 5v and negro-negro for GND)

Those power strips are, basically, plugs whose power is controlled by a solenoid and the main switch (network - switch - solenoid - output)

Edit: I specify the specific pairs that should be used.

Sorry for not replying before. I appreciate the information. The USB thing doesn't exist as an option. And messing around with the connectors is beyond my knowledge. So I only have the option of turning off the power supply so that everything turns off.

In any case, thank you very much for your help.
