I have an SSD and since I got it I've always change the hibernate mode of my Mac to '0' instead of '3' via the pmset command in terminal and then I delete the ram-sized sleepimage in /var/vm to reclaim some disk space. This means that the Mac sleeps instantly (doesn't write that 4 gb file to the ssd every time the lid is closed) but you lose out on the feature where if you run out of power the computer will be able to restore to that previous state when you recharge it. So I got my new MBP yesterday and I used it for about 3-4 hours past full charge and removed the cable. I ran it down all the way and then it eventually just shut itself off after 1% (because hibernatemode is at 0). It didn't go to sleep prior to shutting off, it just went from on to completely off. I let it sit over night, not plugged in, and I notice now this morning when I hit the button on the left side of the casing to check the battery charge level it just blinks a single green circle. Does anyone know if this means the battery is fully discharged? Or should this LED not come on at all if the battery is really empty? I'm just wondering this because I'm unsure if the battery went through all of its reserve power without the standard hibernate mode. Maybe with the hibernate mode set to 0 it uses all of the reserve power instead of going to sleep when it's almost drained? I guess this would explain why after 1% the computer just shut itself off like if you yanked the power cord out of a desktop (probably not the best thing to do.) I just want to make sure my battery is fully discharged before i recharge it.
