ASUS MAXIMUS IV EXTREME-Z 3304&3402 BIOS CAUSING I/O Conflict Cant wake from S3

[digmeahole]

Ticket# 1929831 On install of either bios mentioned in title you will lose the ability to wake the PC from Sleep State. After 2 days of diagnostics test I found the cause. After installing these bios updates.

if you go to device manager and open up Microsoft ACPI-Compliant Embedded Controller and then click on resources tab and look at the bottom where it says conflicting device list it states

"acpi compliant embedded controller Input/Output Range 0066 - 0066 used by: Motherboard resources"

I told the rep everything and the only fix was to downgrade bios to 1004 on second bios chip. Lets see if they fix it..... PS this cause was found under a clean boot with no extra hardware attached. ASUS WE NEED A FIX HERE PLEASE.

you are correct i typed it backwards lol

does it happen if u disable sli?

[digmeahole]

yes. Even with 1 card out. When trying to come out of sleep state there is no usb power and no video output. after bios 1004 .

One thing i did notice is that after 1004 in bios under advanced then cpu the option for C state limit is gone i always had that on no limit but the option is no longer in the newer bios..

I've got the exact same issue running on the latest 3501 bios.

First had the USB issues where the majority of ports either wouldn't work or would stop working. Upgraded bios and now this.

Haven't checked for conflicts in driver manager but will do so later today.

Now have no usb power during S3 mode and pressing the power button makes the pc start without screen output.

Has there been any resolution to this found? Or a working bios version?

These sleep related issues with the new bios have been escalated to the BIOS team for attention. I will report back when there is further updates available.

i also have these sleep issues and usb power surge issues on 3501 and i have issues with cold boots. when it does boot it hangs in windows startup animation. it does this with a fresh install of windows as well.

Is there any idea of when the fixed firmware is going to be available? Getting sick of having to shutdown/startup each time I want to use the computer.

Hi Hivisman. Has the bios team made any progress with this yet?

Thanks
