    When my battery reaches 0% the Mac suddenly goes off, and it takes a long push of the power on button to get it to start again, in which case it acts as if had been shut down abnormally. Before I used to get warnings before the battery ran down, and it would go to sleep rather than switch off abruptly. Is there any setting I can change?

    I am wondering if your battery is properly calibrated.

    I think it is calibrated as I went through that process. Anything else I can try?

    The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries in older Apple notebooks.
    PRAM/NVRAM has nothing to do with battery/power/charging issues. Resetting it will not help. Only resetting the SMC addresses such issues.
    For battery, power, or charging issues, you might try resetting the SMC.

    The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.
