[QUOTE="luftikus143, post: 1802973, member: 337583"] Hi, suddenly, my MacBookPro 17", El Capitan, won't fall asleep anymore. Turns down for a few seconds perhaps, but then comes back again. Upon "pmset -g assertions" it says: "Idle sleep preventers: IODisplayWrangler" I tied a couple of times resetting the SMC, as well as the NVRAM. I reinstalled the OS. I erased the disc, reinstalled the OS, reinstalled the user from backup. Nothing, always the same. Which gives me the impression it's a hardware thing, and not a software. Any hints? I found only a few posts on this, most of them with a solution (if at all) via the print queue - which can't be the case for me (fresh install OS X)... [/QUOTE]
