Hi all,

Hope I can get some help on this issue that I can't seem to resolve:

Ever since I've updated my bios to the latest version my computer turns on after 10-15 secs after shutdown. This happens whether I hold the power button down, or shut down Windows normally.

I've tried switching to the backup bios via the jumper. Which worked fine at first. Then I did the update on this bios as well. Now both bios have the same problem.

I've checked several times to be sure wake on lan or some power options were not the culplrit. I'm at a loss on what is causing this.

Please help!!! Ouch

I never had this problem with my Z170 Extreme7+ board.

Normally the default setting for the following options are set correctly, but check:

In Chipset Configuration, the Deep Sleep option should be Disabled.

In ACPI Configuration, the Suspend to RAM option should be Auto.

Hi,

I confirm that these options are set as you mentioned. I've even tried turning them on, reboot, turn options off again, reboot, and it's still happening..

I am sure you've checked but are all your wake-on settings off? Wake on lan, etc and all your Power-on settings under the APCI configuration in the UEFI are disabled?

Hi TimH

To answer your question, yes. It was among the first things I checked. I looked carefully over every setting in my bios and all power-on settings for LAN, mouse, keyboard, etc. are all disabled in the APCI menu.

Have you disabled the following?

1. Boot from onboard LAN (under boot menu)

2. USB Mouse Power On (under ACPI menu 2 - 7)

3. USB Keyboard/Remote Power On

4. PS/2 Keyboard Power On

5. PCIE Devices Power On

6. Ring-In Power On

7. RTC Alarm Power On

Lastly you can try disable:

ACPI HEPT Table

If none of the others help. From what I have been reading it seems windows 10 has some level of control over the UEFI but I do not see an option to set event timer priority to BIOS rather than OS as described https://communities.intel.com/message/231632" rel="nofollow - here . I suspect HEPT mode being disabled may achieve the same effect but in a less than ideal way as it looks like it disables the entire feature rather than assigning priority. Bare in mind this is just a guess on my part as I don't have a Z170 system of my own to test with.
