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 old G5 dual 1.6 will not go into sleep mode. I had upgraded to 10.5 but several of my photography programs would not run so I reverted back to 10.4 by reinstalling the operating system and not wiping the drive clean. I now must shut down everytime or the G5 will get to the point that all of the cooling fans are running full speed and it will not go into sleep mode automatically. Any suggestions other than a clean install?

after having installed Leopard, my Mac doesn't go to sleep anymore. When I activate the sleep mode, it begins to "shut down" and the fans begin to blow. Normally, shortly afterwards it would sleep, but now the fans blow and blow and blow and nothing more happens. Using the mouse wakes the Mac again.
I've been fighting bad sleep crashes for over a year. Sometimes it would freeze when it started sleep, sometimes when trying to wake from a sleep. I've spent countless hours researching the problem, reading everything on the boards. I tried resetting the PMU, turning off Bluetooth, removing all USB, and all of the other suggestions. Nothing alleviated the problem. Last week I replaced the lithium battery on the mother board because it wasn't keeping the correct time. So far it is sleeping and waking perfectly for the first time in ages. No more freezes or jet engine fans. I have my fingers crossed. Power Mac G5 dual 2 GHz, purchased June, 2003

When my computer is about to go into sleep mode or when it is being activated from being inside sleep mode or any time my computer goals idle for 10 minutes or so something inside my computer clicks. So far there has been no problems is this a normal sound to here?

First, sorry for the longer post - I have to explain everything. I just bought a 24-inch iMac, Mac OS X 10.5.7, 2.66 GHz Intel Core 2 Duo, 4GB, 1067 MHz DDR3. I also just bought an uninterruptible power supply (UPS) from CyberPower. Everything's great, but I still have this one question which is bugging me. What happens when my iMac is in sleep mode and the power goes out? I have set the settings so that my iMac shuts down after 10 minutes of "battery" (UPS) usage, but I am not sure if it will do that when in sleep mode? The UPS is connected to my iMac via USB cable so that they communicate to each other in the case of the power outage, etc. This is what somebody wrote elsewhere on this topic: "Using the Deep Sleep widget, I've worked around this issue: I changed the default sleep behavior to Safe Sleep (hibernation+sleep).When I'm on the grid, my computer will now safe sleep after 3 hours of non-use. If I go off the grid and onto UPS while the MP is awake, the Energy Saver preferences will safe sleep after 1 minute. If for some reason this doesn't occur, Energy Saver will invoke a shut down after 5 minutes. If I go off the grid and onto UPS while the MP is safe sleeping, no big deal since contents are written to the HDD and RAM with this configuration."
I've downloaded the Deep Sleep widget and am using it now. Obviously, the user up there is using a MacPro, and not an iMac, but it should work the same. So, I am not concerned about losing data, and blah, blah, blah... what I am most concerned about is my iMac not working properly because it wasn't shut down properly. I know that there is a very low risk of this happening, but I've spent big bucks on this iMac and I want to make sure that it is shut down properly 100% of the time, if I can help it. If my iMac loses power when in deep sleep, will it be ok? Obviously, I am still using the UPS in deep sleep, but that UPS (battery) power will not last long and will shut down. I am going to turn my iMac off when I don't plan on using it for several days, but if I'm just out and about and the power goes out and my iMac is in deep sleep, will it be ok with the power going off? I contacted CyberPower and this is what they had to say after a long back-and-forth. "You will want to use the deepsleep tool. I had the belief that sleep was the same as windows hibernation where everything is saved to disk. Since deepsleep will save to the hard disk, you would not lose anything when the power is lost when the battery runs out." Despite all of this, I wanted to hear what everyone else thinks about this, especially those of you who might have experience with this kind of stuff. What do the rest of you do when it comes to UPS, etc.?
is there a way to setup my MBP's Power Button to make the laptop directly and without opening additional windows enter sleep mode?Closing the lid to enter sleep mode is no solution
View 4 Replies View RelatedI'm having a problem with my PowerBook G4 where is goes into sleep mode at random times. 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.
iMac 27 locking up after sleep mode requiring full power shut down and rebooting in safe mode then shutting down and rebooting normally.. Permissions and this check show no errors, the only error sleep mode failure. Boot up is very slow as well as wake up when possible is slow. Yosemite seems to need a new release in order to correct the boot problems. System operates more like a Windows machine than Apple machine what's going on?

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.

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 ...
