mrsmithy Posted July 5, 2017 Share Posted July 5, 2017 Sierra, Dell Optiplex 9020, i7-4770, 24GB RAM, 256GB SSD, DP screen on Intel HD 4600The machine will sleep fine, but it will not wake up properly. When using some of the darkwake flags, it will reboot instead of waking; with other darkwake flags, it will wake up partially: the HDDs will start spinning, but the monitors will remain blank such that the machine must be rebooted. Can anyone suggest a solution?Thanks! Link to comment Share on other sites More sharing options...
