Have an A1466 that doesn't come out of sleep when on battery alone, at least more frequently than on charger as well--have not observed it while on charger. Reballed the SMC. Passes ASD OS with no issues. When the unit tries to come out of sleep, it just hangs with a black screen and active backlight. Eventually the unit will shut off and reboot with two chimes as though it PRAMed itself.
