    Here's the problem.
    I put my macbook pro early 2008 to sleep and unplug the power cord. I go on a 4 day vacation and I come back the battery is dead. Is that normal? :(:(:(

    Yes thats normal. Sleep mode uses more battery power than you might think. If you're not using your computer for 4 days either plug it in while it is sleep mode, or turn it off (I usually keep it plugged in at home all times).

    It does use more than I thought too. So, I use DeepSleep if I need to leave for awhile and save what is running. It works well.

    Noticed my Mac has gone into a deep sleep from time to time but I am not sure exactly how or why it did it. Seemed to be when the battery was almost dead or something. This was without any additional software.

    It's probably running on reserve power.

    If I remember correctly, it's something like 1 percent every hour when sleeping or something very close to 1 percent.

    ...does it depend on the apps that are on your dock?

    I leave my whitebook unplugged for days, using it at work and sleeping it and I can easily go for 4 - 5 days before plugging it back in... mostly used for checking yahoo mail or google docs...

    it depends on how much RAM you have installed

    Some MBPs had a problem consuming up to 3% of charge per hour of sleep, so that might explain the discrepancy of the White MB's sleep pattern during its REM phase.

    My iBook could on for days sleeping on one battery charge, but it had only 768MB of RAM installed.

    My Unibody 15-inch MBP did take 3% per hour, and my new June 2009 17-inch MBP seems to have a good battery and only uses about 1% per hour, which should amount to roughly 100 hours or 4 days of uninterrupted sleep.

    ...it will be interesting to see how my whitebook does now, today I just installed 4 GB of PC6400 RAM in it... backing up now to clone and install the WD 320 GB Scorpio blue as well...

    hard-drive has nothing to do with it, only RAM stays powered.

    mine just took 3% in little more than 60 minutes. :)
