Motherboard still powered when shut down

[Jaymie1989]

Hi,

When I shut down my PC, The USB's and the PS/2 is on and the leds are lit up like a Christmas tree.
I done some googling and it appears that their is an option in the BIOS to disable the power on USB's when the PC is off but I'm not to sure what to look for. There are a few USB options and nothing on Google is clear on what option I need.

MoBo is a ASUStek M3A78-CM.

Look for something called EuP in your bios. If you see it, enable it.

Edit; Its something to do with power management settings.

If available, the settings should be under "onboard devices" and/or "advanced".
See if there's an updated BIOS on ASUS' site.

But, I think it's an oddity with the AMD 780G chipset - my GA-MA78G-DS3H motherboard doesn't shut the USB ports down completely...

One whole month before I reply lol.

I can't see either of them options but I have images of what I do have.

I'm going to do the BIOS update now.

[Jaymie1989]

Could you look at the BIOS updates for me please Nick?

There are fix's for every one released but not one with all the fixed in one.
And what is the BIOS utility?

[eneles]

The latest BIOS contains all previous fixes - i.e. it does NOT work like, for example, Windows update.
The BIOS utility is a small DOS program used to flash BIOS. You can run DOS programs from a USB drive - check our articles.

[Jaymie1989]

What about running it from inside Windows? I done it on my other system.

Is it the better option or not?

[eneles]

It is usually NOT recommended to flash BIOS from Windows.

[Jaymie1989]

Ok, I was just wondering.

I'll do it from USB.

Thats the new thing I learned today

EDIT:

Which OS am I going for?

Linux, Win 2K, XP, Vista, 7 or other?

I'm thinking of Linux as its for the DOS but I'm not sure again.

[eneles]

As running the DOS utility is done "pre-OS", it should be the same regardless what OS you have installed.

[Jaymie1989]

Still having an issue.

I followed your article about running dos program from USB but instead of copying ES Tool, Added the BIOS update .rom but it only takes me to DOS. I cannot start the BIOS update. I have tried "run" "setup" I renamed the BIOS file to ASUS.ROM and it wont do anything when I type that in either.

What Do I do?

[Jaymie1989]

Scratch the above.

There is a utility for ASUS that does the update for you from file or their server. Although it can only run via program in Linux or Windows. Nothing for DOS.

Although it's not generally recommended, I've twice updated my Asus M2N4-SLI BIOS from Windows with no problem - I do hold my breath whilst it updating though. It's your final choice though, no guarantees

[Jaymie1989]

It worked

That was the only way I found out how to update my BIOS. I still only have the options that are in the images I posted Motherboard still powered when shut down

[eneles]

Guess you'll just have to accept it's a "flaw" that comes with the board - I disconnect the power when I leave home.

If pressing your power switch doesn't immediately shut down the PC The motherboard power must remain connected to activate the ATX power supply.If power still comes on, try the last adapter you removed in different slot

One thing that comes to mind .. if you have "enabled" power on from keyboard, mouse or any of the other currently standard option, you will need power to those devices. The Power is fed from the 5Volt Standby voltage which is always on until the main switch is thrown .. disabling these features might help you.
My Asus always leaves power to my optical mouse, which I find quite helpful, since I always check my room as I am leaving, turning the light off, so the glow from the mouse warns me to turn of the main switch on the multiblock. This kills power to everything including my wireless router.
