i did the following
On start up, press F2 to enter the BIOS....then go over to Advanced and scroll down to USB Legacy Support. Disable that, press F10 to save and exit. Your machine will reboot. You should be good.
AFTER RESTART SETTINGS GO BACK TO HAVING USB LEGACY SUPPORT ENABLED
Next I did the following
1.Opening up the terminal and typing "sudo pmset lidwake 0" (without the quotes obviously). This is the only unnecessary step but it helped other problems I had where the screen would open and would be completely black, so I would recommend doing this, this just prevents your computer from automatically waking from sleep when you open the lid and you just have to press the power button to wake from sleep.
2. Next type "sudo pmset hibernatemode 3". Not sure what the 3 mode does differently but it defaults to 1. You can check that all these commands worked properly by typing "sudo pmset -g". Make sure you spelled hibernatemode and lidwake right because I don't have my Hackintosh in front of me so I am spelling them from memory.
3. Next just restart your computer and hit F2 at the dell screen to open your BIOS. Go to the advanced tab I believe and disable the option "Legacy USB support".
Again USB Legacy reverts back to being enabled upon restart. Also when it falls asleep even before the restart my Mini doesnt wake up. It shows a black screen so/ I press the power button and it still just shows the black screen
