I've searched this forum and tried various ways to get wake up to work for me on ML. I have the following rig:
Gigabyte P55-USB3 Rev1.0 F9 BIOS MSI GTS 250
I have the following kexts installed
AppleRTC.kext - Patched NullCPUPowerManagement.kext JMicron36xATA.kext ALC8xxHDA.kext FakeSMC.kext
The issue is that whenever I put the machine to sleep, all my USB devices power down (or are unavailable) but the system keeps running. There is no way for me to wake it up from this state except for a power recycle. This same setup worked for me beautifully on Lion in which the system powered down and pressing any key on the keyboard brought it back.
Any help or links would be highly appreciated.
