Dell Optiplex 960 - Need Help Fixing the Sleep Issue


1 post in this topic

Recommended Posts

Where do I begin?


I have ML 10.8.5 running well on a Dell Optiplex 960, but it won't recover from sleep mode. I have to force a hard boot.

FWIW, I have the BIOS set to S3, not S1.


Is a DSDT required for this particular machine?  Or is it something that can be done with Chameleon Wizard?


How do I obtain or create a custom DSDT for this machine, so it will recover from sleep mode?


Thanks - any help would be appreciated.
