    My MBP (2.4 GHz, 4GB RAM, SSD) does not go to sleep when it is at low battery. I get the warning pop up about the low battery like I should. However, when it is time, the laptop shuts down instead of going to sleep.

    The battery is 100% health with 11 cycles.
    I've calibrated the battery, reset the PRAM, and the SMC.... but nothing seems to work. What should I do? (I am planning on calling Apple tomorrow since it hasn't been 90 days since my purchase yet.)

    Have you waited until it says 1-2% and closed the lid for 5 hours then let it charge until the light is green before booting?

    Sounds broken to me. I dont think the previous poster is correct - it should sleep itself when it gets to about 2% battery life and then eventually turn itself off. I had the same issue on a 15 month ld SR MBP, called Apple, got a new battery in the post that works as it should. You wont need to send your whole laptop back.

    I just called Apple and their so called "Specialist" told me that this was expected behavior. This is a load of BS because, I've used many of Apple notebooks and none of them have been shutting down abruptly.

    His explanation was that I was not plugging in the AC Adaptor right after I get the Low Battery Warning. Like I said, I've used other laptops beyond this low battery message and they last me 5-10 minutes before going to sleep.

    The attitude that the rep gave me makes me want to ignore his battery return offer.

    So the rep offered to replace the battery, which as stated in the thread should fix your problem, but you think keeping your defective battery is going to "get" him somehow? You can't be serious..

    When you press the power button, does it start up, then go to a grey screen like your last screen and then resume? If so, then it's not shutting down it's hibernating. This is how it's supposed to work if the battery level is too low to guarantee that sleep won't run out of power.

    No it wasn't hibernating. Would the new battery really solve my problems?

    I don't know. I've never seen it not hibernate unless power was somehow terminated. If you have a store near you I'd take it to the genius bar and duplicate the problem for them.

    mine does not shut off, but seems to go straight to hibernate. my last MBP would sleep and would stay in sleep mode for at least 8 hours before hibernating.
