Here is my HW: Asus P6TSE Intel i7 920 Nvidia GTX 285 I have successfully loaded a stable SL 10.6.6. Only issue is that monitor will not wake up from sleep. The computer will sleep and wake up, but monitor will not. S3 is configured in Bios. I am using PleaseSleep app because the P6TSE SL Install said it was the fix, but is not...well in my case. Thanks in advance.
