    Sleep vs. shut down
    I'm going to leave my MBP plugged in over night. Should I let it sleep, or actually shut it down when I go to bed?
    Don't know what I'm supposed to say, but I keep speaking these words anyway.

    I never shut down my Mac Pro Dual-Core Intel Xeon…I just tuck it in and let it sleep all night. I've been doing this for years without the first problem. I'm one who believes the peaceful, gentle nudge to wake the Mac in the morning is less stressful than the shocking "BONG – IT"S MORNING…WAKE UP AND GET AT IT!" The only time I shut down is if I'm leaving town for a couple of days.
    I don't know what tomorrow holds, but I know who holds tomorrow.

    I agree. There is no reason to shut down the laptop during the night. It won't wear your computer down or cause it harm.

    Depends how high you want your electric bill to be.

    I would think this depends on if you want to wait for the machine to have to boot up or be readily available.

    This is a fairly ridiculous answer -- a sleeping Mac using almost no power, and a completely shut-off Mac uses about the same amount (yes, a shut-down Mac that is still plugged in continues to draw a trickle of power!).

    The total difference in your electric bill over the course of a year of doing it one way or the other would amount to no more than $1's worth of power.

    Apple themselves suggest that their computers are designed to be put to sleep when not in use UNLESS you will be leaving it alone for a prolonged period. I've always found that its generally best to do as Apple advises until you find a good reason not to.

    The night is long, and I think that some hours off is good for ANY device.
    As others said a Mac can be totally fine with sleeping...but i always turn it off when i go to bed. During the day i usually just close it and let it sleep.

    That's what I was thinking.

    He's talking about Macs, not a collection of random electronics from some study.

    A modern Mac will not waste "watts" of power. It will "waste" a watt or so. Which, over the course of a year, will add up to a dollar or two (US) of power.

    I just let mine sleep. For a little while I shut it down nightly and it seemed more sluggish the following day!

    Here is a decent blog post on what a relatively modern mac draws.
    David Alison's Blog: Power off or sleep at night?

    Check out the chart in the middle generated off of his APC backup battery
    In sleep mode - 0 watts used, 0% battery load and 785 minutes for battery backup

    Don't forget that your hard drive gets accessed a lot when you boot your computer - so you are putting wear and tear that you may not need to on your hdd. (Hence the faster boot up times from SSD drives, and since there are no moving parts and you are mainly reading it may be a moot point for SSD based computers)

    I don't think it really matters since a modern Mac computer, whether it's a notebook or desktop uses negligible amounts of power. Like Technologist said, it might amount to a dollar or so a year.

    Now having said that.... if you live in an area where severe weather moves fast and the likelihood of thunderstorms and lightening is great, (Texas and Florida are good examples) I highly recommend powering down and remove the AC adapter. Even an UPS is not sufficient for protection during a severe lightening storm.

    Regards.
