Hi! I've just build my new system: Gigabyte Z77X-UD5H (bios F8 - latest available) / 3770K / 16GB Corsair XMS / Gigabyte GTX 670

As I thought when reading some other forums, on this MB I don't need a DSDT and sleep/wake should work OOB.

Maybe they were wrong or I did something wrong but I can't get sleep mode working.
Monitor goes off but system didn't power off. If you know a solution to this problem or have working sleep mode please post your kext/enablers configuration.

My sleep doesn;t work either, but I haven't spent much time trying to get it to work as I dont use it. But yet I was expecting it to just work same as you :)

I Just found a solution by myself. MyHack installed a "NullCPUPowerManagement.kext" but it should be removed when we use z77x-UD5H.
So look for it, delete, rebuild caches, add darkwake flag in ChameleonWizard and sleep should work fine.
But for my system I have some weird sluggish mouse after system wakes up. It stays for 15-20 sec and then go away and system works well.

I have the same board and I'm having that 20 second delay after wake. I see my desktop, but only after about 20 seconds later mouse, lan, etc starts working again.

I have the same problem! It also registers USB drives as "removed without being properly ejected" or whatnot, as the system simply does not recognize the USB hardware for those 20 seconds. It's just not there.

Any leads on this would be awesome!

The mouse being laggy and the USB eject problem come down to the processor or memory overclocked in the bios. At stock speeds this should not happen.

Also make sure darkwake=no and not darkwake=0 or else auto sleep might not function.

Can this be solved with SSDT edits?
