I had to renew my PC lately, because my motherboard exploded.... but that's another story...
Anyway now, as you can see from my specs, I have a good motherboard and CPU. I have a retail installation with EFI 132 boot (just a few kexts to make it work perfectly well). For the sleep/restart I'm using OpenHaltRestart.kext.
It works PERFECT, but as I wrote in the title, if I want my computer to sleep, I have to use the apple menu. It doesn't go by just clicking the power button.
Of course from System Configuration I have checked the option that allows the power button to activate the sleep mode.
Any ideas?
Thanks.
