Turning Off & On my iMac

Message #1 - Posted 2011/04/17 - Gerry

I had an unexpected experience when I was trying to adjust the tilt of my mid-2010 27" iMac (running OS 10.6.7) by grabbing the outer edges at the bottom and accidentally pushing the power button, the computer just shut off with out any warning, after a brief hesitation I pushed the power button again and the computer came back to life with all the open applications just as they had been.

I did not expect that I would be able to return to where it had abruptly left off. Is this normal behavior?

It never really completed the Shutdown, and went into Deep Sleep Mode... this is a "Feature".... NOT a BUG.... Fell Grateful......

Actually, Gerry just put the computer to sleep. Whether it was deep sleep or regular sleep isn't really important in this scenario.

Gerry: Take a look at the System Preferences > Energy Saver panel. You should see an option named something like "Allow power button to put the computer to sleep". If this option is checked, the computer will sleep when you press the power button and wake up when you press it again. If this option is not checked, pressing the power button will do nothing.

For the curious, here's how Apple defines deep sleep:

Thanks for all the replies. I was just surprised that the computer didn't just shut down, now I know the reason why, and yes the option to sleep with the power button was selected.

It will shut down, not sleep, if you hold the button for five seconds. Not a recommend way to shut down. Use as a penultimate resort. (Pulling the plug is the last resort.)

Indeed. This is considered a forced shutdown, and may leave the directory of the startup volume in disarray, which is a bad thing. These days, most startup volumes are journaled. With journalling enabled the system can repair the directory at the next startup - though that's not something you should count on. The other problem is that applications / processes with files that were open with unsaved changes at the time of the forced shutdown may have left those files in an incomplete or corrupt state. Journalling cannot fix that.

If he presses the power button long enough -- I think it's four seconds -- the computer will power down.

This then is truly digital technology.

for what it is worth, I stuck a self-adhesive plastic button on the power button n my mac, so I can feel exactly where the darn button is without having to eyeball it. The button is so well finished and fit into the case that I cannot feel it with my (lightly calloused) fingertip. Now, if I grab my computer as you have grabbed yours, I can feel exactly where the button is, and not accidentally put it to sleep.

I will find a way or make one.
