    Hi all,
    I just purchased an iMac and got it unboxed and onto my desk. Every time it goes to sleep I'm not able to make it by pushing the power button or the keyboard or the trackpad. The only way to get the computer on after the screen goes blank is to turn off and reset the power strip that it's plugged into. This doesn't seem right to me, does anyone have any suggestions? Thanks!

    Have you tried it not plugged into the power strip or done an smc reset? If you are unhappy and its brand new get it exchanged within your 14 days. Also you should really have it plugged into a UPS, they can really save you a lot of heartache. Surge protectors don't have AVR for a start to smooth out power glitches, let alone power cuts.

    Ok, you're speaking a foreign language! UPS? I haven't done an smc reset yet. Should I?

    UPS (uninterruptible power supply) you can get them cheaply and you don't need a pure sine wave one for an iMac and it will protect your machine from crashing when the power goes out, and lets it shut down gratefully. I use an APC Smart 1500 which is pure sine wave but it powers a few things that need that, like a big fan. Yes try a SMC reset and try to not use that power strip and see what happens. If it still does the same thing contact Apple and ask for a replacement.

    I had the exact same issue with a new iMac. send it back. it's defective. Mine when it went into sleep mode would not wake up unless you held the power button for 5-6 seconds effectively powering the unit down and then turning it back on.

    A UPS is an Un-interupeded Power Supply. It's basically a big battery that you can plug your computer into so that if there is any power issues like a blackout or brownout (sag in the power) the battery kicks in and your computer gets clean power. There is a whole load of questions about types of UPS's that will and won't work with a Mac that I would suggest not looking right now, but get someone from apple or an apple store to give you a hand with that in the future.

    It wakes from sleep mode if I put it in sleep mode with the apple menu, but not if its been in sleep mode for awhile (probably shuts down), say 45 min or so? (I'm not home so I can't try a reset at the moment yet).

    Try reinstalling OSX if that doesn't work get Apple to replace or fix it under warranty

    Ignore the other posters!

    If you bought the computer from Apple, you have 14 days to return for exchange or refund for ANY reason. If you bought from a reseller, return for exchange.

    You also have 90 days of complimentary AppleCare phone support, contact Apple immediately!

    >>> If you bought the computer from Apple, you have 14 days to return for exchange or refund for ANY reason. If you bought from a reseller, return for exchange.

    +1 to that. It should work properly out of the box. The vendor should make it right for you.
