    Leaving your Mac on for anytime more than 50 hours could seriously damage the BS infrastructure - contact your nearest retailer immediately, you'll need to buy some Mac coolant, and the retailer should be able to tell you exactly what you need to do. But DON'T turn your Mac off now until you've added the coolant, or the damage may be irreversible...

    Leave it on, if reasonable...


    So long as your room temperature doesn't exceed 95 F, you shouldn't worry about it.

    If your room is typically warmer than this, then yes, turn it off when you're done using it.

    If you're not going to be using it, turn it off and save some electricity, if you're stepping away for a little bit you can sleep it.
    Seriously that old "keep 'em running all the time" thing is probably the real reason behind California's power crisis.

    power usage...

    Good point on the power usage thing.

    The advice should probably be dependent on the machine we're talking about. Older machines don't have the same power-saving features of newer models.

    "Sleeping" the machine on newer models is a good compromise. And, of course, you should probably be using the energy saver control panel to do that in feasible situations anyway.

    I've had my cube on (running os x) for about 30 days straight. I haven't noticed any problems. I just set the display sleep to 10 or 15 mins.

    Sometimes I'll put it to sleep (by pressing the power button) but I haven't had to power down (cept to install updates) and everything seems to be running fine.

    re: computer power usage

    many, many homes and businesses keep the cpu on all the time and that cannot help the california power crisis but a computer only needs a small amount of juice

    i blame it on all the hot weather people who move to chilly northern california and try to keep things in their home tropical...i see it all the time

    and in the southland where its hot, people keep the ac running at a meatlocker level

    it's like blaming air pollution on smokestacks when it's the zillions of cars in califnia that account for almost all measurable air pollution

    You forgot:
    Diesel Trucks and busses. Ever drive behind a natural gas powered bus in San Diego? No smoke.
    Server farms, and their diesel generators during rolling blackouts.
    Poor design of homes and businesses.
    Overtaxed infrastructure, see overpopulation.

    California's a mess these days, I moved up to the Northwest in January and I laugh when I get my power bills. Haven't paid more than $12 a month yet.

    Heat heat!

    To have a computer on for a few days is not harmfull, may be in the 80's but remember that when we have one computer at home there are companies and schools, production houses, etc. that have their equipment runing for the entire week even 24 hours a day with PCI cards and memory sims in every slot.

    What is bad for a computer and any electronic device is to be off for weeks or months, humedity can harm the unit.
    When you come from vacation, tur on your computer just for an hour or 2 before use it.

    I work with lots of audio equipment, usually when I turn them on after a few months they come with wird sound and noises. I have a Roland sintetizer module that I didn't use in 8 months for more than 2 hours. I turned it on 3 days ago and it was making wird sounds in the back ground, I thought the unit was **** up. After 10 hours it was working as brand new, I'm sure the internal heat remove the humedity from the circuits, 3 more month and may be I would lost it.

    So, heat can resolve most of the problems.

    Another tip is not having a fan pointing to the unit at all times, you may be introducing humedity and dust, many amateur audio engineers do that, they push air in place of pull the heat out. If you push air in to an aplifier in a club, after one week you are gonna end up with a sample of every single cigarret, dust, and kitchen oil on the unit.

    if it's not getting too hot, then leave it on!
    i have an older iMac with a fan and while
    it doesn't seem to function less efficiently,
    the back/top of it gets VERY hot. my ibook
    obviously doesn't have a fan, and as most
    if not all laptops it also gets very hot, with
    no problems observed. I did have an older
    computer though, and by older i mean
    summer of 1983, and in the summer it's
    display would go from it's standard blue
    to a very ugly "help-i'm-frying " shade of
    brown. that being said, i think you should
    leave it on. get a gnutella client, put tons
    of mp3's in your shared folder, get a broadband
    connection if you can, and leave your computer
    on 24/7! as martha would say if she had a clue
    about such things, "it's a good thing!"
