    Hi,
    after the discussion about the battery loss during sleep, let talks about the loss during hybernation.

    When I put my late 08 to hybernate, it still loses some battery. It's around 3% for 8 hours of hybernation .... is that normal ?

    Thanks,
    Tex

    Was it charged 100% before you hit hibernation? What is the ambient temperature?

    Batteries can lose charge without being on, so give us some more information ;)

    The battery was 27% and when I switched the mbp on this morning, it was 24%. The temperature was ambient, around 20ºC.

    Well when you're hibernating the computer still keeps stuff in RAM, so yes you will still over battery capacity. The only way to prevent is to remove and replace the battery after you hibernate.

    Are you sure about that ? I read that THE difference between sleep and hibernation is that in the 2nd case, everything from the RAM is dumped to the disk and then everything is just switched off.

    Deep sleep/hibernation is supposed to place no drain on the battery.
