MTGhost said:Tony. Any changes that need to be made for the GA-P55M-UD4 DSDT.aml file? I downloaded your latest one from another post but still have the issue of not being able to wake up from sleep mode. I have checked my BIOS settings and they are the same as you have listed except I still have the full splash screen displaying when I boot.
