Thanks for the link, downloading now. Looks like a lot of pain to install to a key disk so maybe I'll try an external usb drive.
I neverr figurred out why it would be any diffferent installing to a USB HDD or Flaash drive? Seems itt would worrk exactly the same way.
Incidentally, I tried an Ubuntu 12.04 LiveCD and a Linux Mint LiveCD and the system still doesn't resume so it's probably not a software problem. I'll try win8 later.
So it looks like the m/board. To eliminate an extremely improbable problem with the PSU 5V standby then I'm going to temporarily wire in an external PSU. I'm betting that there's no difference. Wonder if it's a one off or a design fault? Maybe a BIOS problem.
It's possible the BIOS, but it seems if it sleeps, but not wakes, it usually memory. BIOS could cause a misconfiguration I suppose..
On my ASRock Z68 Extreme3 Gen3 I would get BSOD on wake from sleep from Hackintosh, but no problems in win8. I tried 5 different sets of memory and was told it was memory. I went and pulled some generic (low-density, single rank, non-heatsink) chips out of my Dell workstation and voila! Sleeps worked fine. If you can rob some generic ram I would give this a try.
I just remembered while spell checking my post that I had a Gigabyte board with wake issues and it turned out it needed a PS/2 device to wake it. I didn't have one and disabled/enabled usb legacy support and it worked.
Sometimes all this debugging is more painful than just doing an RMA. lol
