    I have a 17 months old white macbook with 423 load cycles and the current battery capacity is 44%. ouch.

    it doesn't go to sleep anymore when the battery is low nor does it let me know when it is running on reserve power (it just shuts down suddenly).

    i tried calibrating it about a month ago and the battery capacity went up to 92% but it went down really quickly. would my battery be failing?

    Considering you have 423 cycles on it your battery is basically at it's end of life.
