Hey folks, I've got a late 2006 17" C2D MBP. After a reboot, my system stopped booting completely - it hangs at the Apple logo, no hard drive activity. It will not boot from my Snow Leopard DVD or Leopard or Tiger DVDs either - just hangs. I've tried the usual PMU, battery in and out tricks. Booting into Safe Mode displays a few lines and then stops on: ACPI: System State [S0 S3 S4 S5] (S3) I can find nothing about this on Google. Also - Target Disk Mode works and I have been able to recover all my files. Not sure if this is relevant. Any ideas? Is this thing just cooked?
