Hi Stefano
Thanks for the follow up. Tried your suggestion, and I can confirm downgrading to 1.5 fixed resume for me also. Though I have not flashed to 1.8 again, yet! I can also confirm my board (rev1.01) arrived with BIOS 1.0 and that I flashed directly to 1.8, in UEFI, before installing any disks. Have to say BIOS/UEFI behaviour of this board feels a little fragile. Some changes I have made result in it failing to boot. Disabling CSM resulted in 5 quick beeps and required a CMOS reset to get back in to the UEFI. I can confirm I also see window resize in windows 7 post resume. Looks like they are sized to VGA dimensions. I also saw this behaviour with the built in intel graphics on a z77x/i5-3570k build. I don't see this issue in Ubuntu, nor do SSH sessions disconnect, like they do with putty sessions under windows. Edited by keeka - 23 Dec 2015 at 5:38am |

To whom might be interested, my PC seems to wake up correctly from sleep now.
I've found another thread in this forum (a couple of months old) with similar problems. In the thread someone suggested to downgrade the firmware (in that case from 1.50 to i.30). I tried to downgrade from 1.80 to 1.50 (from Windows) without any other change (not even entered in BIOS settings) and wake from sleep was working correctly. Than I decided to flash back BIOS version 1.80 (from Windows), again without any other change. And wake from sleep works correctly even on 1.80! So to me the problem seems some kind of bad configuration that was reset downgrading the BIOS. I don't know if it may be relevant but when I bought the board last week it had (I think) BIOS version 1.00 and I upgraded directly to 1.80 from the BIOS itself, without even installing Windows. I've not done extensive testing but, since before it was failing all the time, I'm positive that I solved the issue. Stefano |

Hi keeka,
I have your exact problem, board and BIOS version! The system exits from sleep only pressing reset button, as you described. I also noticed that when the system exits from sleep the open windows are very small, as if the resolution was changed to a very small one and then back to normal (I use 3840x2160). My system: ASROCK H170M PRO4 BIOS 1.80 I7-6700 Kingston hyperx Fury 2x8GB DDR4 2400 @2133 Corsair RM650i PSU Samsung 850 EVO 1TB Windows 10 completely updated. All drivers updated Monitor: Dell P2715Q Rev A03 @3840x2160 I hope Asrock may help here! |

Hi
In order to resume from sleep, I have to press power then reset. Pressing the power button, powers up the machine, but it does not fully resume (no display and machine does not respond to ping). Then pressing reset, resume completes (no hard reset occurs), network interfaces comes up and I'm back at the desktop. Enabling wake from keyboard or mouse in bios gives same result as hitting the power button to wake: system does not completely resume until I press reset. I have also tried enabling all ASPM options in UEFI. Though this makes no discernible difference. Behaviour is same in both installed OS. Any advice appreciated.
