MacBook Pro doesn't sleep when lid closed
My Mac doesn't go to sleep mode when I close the lid. I still hear the noise of the vents that occasionally start working.
I tried finding the settings in Energy Saver, but apparently I only have two settings:
- Put HDs to sleep when possible,
- Wake for network access

Can any one advise please?
