My iMac keeps shutting down in after about an hour in sleep mode. I have to press the power button to turn back on. Energy saver settings are still default settings. I'm running osx 10.7.4.Â

New mac user, just bought a new MBA -- when should I just close the lid vs shutting it down completely? i.e. is there a general guideline where if you're not going to use it for at least, say, an hour, then shut down but if you are then close the lid, etc. Also let's assume we are talking about the MBA not being plugged in for this scenario but operating off battery.Â

View 17 Replies View RelatedSo this past week when my mini hasn't stayed in sleep mode, it shuts itself down about a minute later after being in sleep mode. I haven't changed any of my settings in a year and a half, normally it would stay in sleep mode until i come back to it and logged on again. When it does shut down i just cannot power back on i have to unplug the adapter then replug it in for it to start up again. I've searched google and on here for possible ideas. I wouldn't think it to be overheating since I'm not running any applications when i put it in sleep. It might be the power supply since i have to do that process to get it to work again. Let me know what could be causing this or ways to troubleshoot this problem.

Mostly when I am streaming video..or at times the fan comes on, it sounds super high then boom. sleep mode again. After hitting the space bar, it comes back on, but it'll happen again shortly after. I've played with the sleep settings
View 5 Replies View RelatedAs of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.
The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.
How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.
my mac is hot even if its in sleep mode..

My Mac would not turn on this morning from sleep mode. I pressed the power button and nothing. Then I did it again and heard the fan shut off inside so I tried again and up it came. Also I cannot wake my Mac up unless I press the power button. I used to press any key on the keyboard or move the mouse and it would wake up, but now that doens't work. I don't know if this could be a reason, but my mother has a horrible habit of unplugging it when it storms. It's always asleep and I've told her not to do that and to make sure it's turned off before ripping the cord from the wall. But she continues to do it when it storms.

Computer would only start after sleep mode if I unplugged the power cord. The power button would not do anything, even if I held it for a long time.
Shut down and start up would work normally. Only effected sleep mode.
After much trouble shooting I found that I had a bad USB hub. Everything on the bad USB hub would work fine so I didn't suspect it.

Is it best to turn off my 27" i7 processor iMac or put it into sleep mode when it's not in use? ie sleep or leave the house. Also the fan has just turned on, never heard it before. I am watching a video whilst converting another into mp4 format. Is that why?Â

My iMac shut itself down last night while in sleep mode. It's rarely ever turned off. I cannot get it started today. I'm not the most tech saavy person but can follow instructions if someone could walk me through it. Â

I've been using Pc's for the past 30 odd years so am totally new to Mac. I'm doing my best to adapt to this new different OS and so far have found some things more user friendly but others ? I've more or less given up on those as Mac doesn't seem to do those things. These are probably Windows based and I'm assuming Mac has its own alternatives that I haven't discovered yet. Anyway, my immediate problem is this goddamned frustrating situation when I try to re-activate the comp' after waking it from 'sleep'. Sometimes its fine but others, it comes back on but freezes and the only option I have is to turn it off at the switch and do a re-boot!

This morning I woke up and my iMac, which I had left sleeping, would switch on. As I discovered, for some reason the power cord had been disconnected. Once I connected it again, nothing would happen when I pressed the start button, not a noise... nothing.

How can I get my iMac to stay asleep?
View 1 Replies View RelatedMy iMac will not come out of sleep mode and if it does it takes a really long time to do so. I've looked at several things in other forums and it seems to be a Maverick issue. However it only started about a month ago and most people have had this issue since the release of Maverick. I also read to use the bluetooth keyboard and mouse instead of a USB one. That also did not fix the problem. So I am at a standstill ...

View 2 Replies View RelatedWhen my iMac comes out of sleep (overnight), I get a "backup failure" error as the machine tries to do a backup. I try performing a backup manually and it fails as well. I tried removing the drive to have it detect again and I get another error that it cannot perform the ejection process, because it may be in use. I have to force quit/eject. After reattaching the drive, the backup performs with no problems.

I just bought my iMac 4/15/2012 and every time after i return from sleep mode or even just a screen saver, i have to wait 10+ minutes just to type in my password. I tried taking the password feature off and yet it still freezes when i return to the computer. the only thing i know to do is to manually turn the computer off, as i have no other options.

I have two different iMacs: late 2011 and Mid 2010. Both imacs wifi stop working after sleep mode. ***?! Ipod and iphones work properly at is time. I have checked disk utils and fixed permissions. Everything is updated. Maybe there is the way to reenable wifi module without rebooting my computers?
Im very dissapointed apple imacs. Lcd of mid 2010 being changing for the second time. Last time it worked ok for 5 month. ***?! Is it ok for lcd screen? Or maybe I should turn into hackintosh to avoid poor-quality hardware? Rofl. **** I have only apple devices and starting nervous about it.
