MacBook Core Duo Optical Drive
After installing an SSD instead of the optical drive, installing Mac OS on it (the SSD) and then booting from the SSD, I can't get the computer to enter sleep mode. When I had the SSD connected (with the same OS installation) to an external USB port I had no trouble putting the beast to sleep (when booting from it)! Any suggestions? Obviously the SSD is now attached via (S)ATA instead of USB. Does it matter?
If I boot from the "original" SATA hard disk sleep mode works fine with the SSD installed (both via USB and in the optical bay)...
