sleep trouble, what sleep trouble do you have ?
My computer semi wakes up by itself. Power light comes on but it does not wake up.
Didn't have this problem before "load optimized default".
CPU fan is rotating, but no display ?
Not sure about CPU-fan. But no display
are you using the DSDT F2 bios downloaded from here ?
you may try enable the VNC options (control center :: sharing :: screen sharing) on your mac
then use another computer to VNC your mac, to check whether the MAC is already on but no video
I'm on F3 BIOS and using DSTS free installation.
But all I need is what setting to change in BIOS, as everything was working fine before I did "load optimized default".
I would say "optimized default" already is a safe settings, maybe have some other problems
Did you modded the bios, like adding SLIC to it
No modded bios just did a "optimized default"
