Yeah, missed that sorry.
Closed all non default applications, even removed the dvd, i normally don't have any in the drive.
Setting 0 to 1 did not work, do not even know if that would be the right command.
pmset -g assertions gives nothing, perhaps i do need to look in to the dsdt again. Just don't get it, it worked before the new installation, and nothing in the kexts/dsdt has changed since then
Btw, pmset -g assertions, was what i was looking for, thanks for the "push in the right direction"
I'll close this topic, question has been answered.
I'm an idiot, perhaps i should delete my kernel cache, damn....
