Sleep when HDMI connected - Acer 5755

[janohan]

Hi,

The situation:
The laptop is connected to external monitor via HDMI. I try to put it to sleep by closing the LID or Apple -> Sleep

(just for information, Sleep without HDMI works well. )

Result:
Both screens black, no sleep, no answer for a button press or anything, hardreset needed.

Any ideas?


Next (optional):
Is there an option in OSX to use external monitor only? With Closed LID maybe?

On Windows 8.1:
In Energy saving options i set "when LID is closed do: Nothing". And it switches to external monitor when lid is closed. Any simillar solution for OSX?

Thanks, cheers

I haven't tested it in a while, but I believe the behavior you describe is the default in OS X. You can use NoSleep to force other behaviors.
