    Hi,
    I have a MacbookPro mid 2009 and have some problems with my battery.
    This morning I noticed that the battery was empty through it was supposed to be in sleep mode during the night.
    My battery has 97 cycles and has 99% of its original capacity.
    What could be the cause of this problem ?
    Thanks

    That's exactly what it's supposed to do, no need to worry

    After your edit, it would be helpful to know how much battery you had before you put it to sleep, as the battery will lose 1-2% of its charge per hour it is asleep. Also, if the sleep light was on steady, that means it wasn't fully sleeping.

    alust2013 is right. If your battery was almost drained when you put your MBP to sleep, it could have completely drained it in sleep mode. You're not providing enough information for us to accurately determine if there's a problem at all. Also, your battery health may be inaccurate, if you haven't properly calibrated your battery.
