My iMac (10.6.8) goes to sleep after 2 or 3 hours (even if im working at the time) and will not wake up without a hard reboot.Â

I have an Early 2008 Mac Pro with an ATI Radeon HD 2600 XT graphics card. Yesterday I could not get the display to wake from sleep in the morning, and even after a reboot I had nothing to look at. Then I (eventually) moved the card to another PCI Express slot and everything worked! Then after a reboot no video again. I moved the card back to slot one and it worked! Rebooted again, no display. Move card again, everything is fine.

I searched the forum, but saw a lot of sleep issues. None quite like mine. I have a MBP 13" bought in June. When I close the lid, it goes to sleep just fine. When I open it, I can hear it start up. The sleep light becomes illuminated, but then about 5 seconds later goes back to sleep.I have tried to hold the power button and shut the computer down, and start it back up. When it starts up, it shows the white screen with the apple logo, then goes blue, and is about to load the log-on screen, and goes back to sleep. I have already tried an archive and install, and a erase and install. Neither worked.Occassionally it will start back up if I just wait 20-30 minutes. Sorry about the long log, but I do not know what information is needed. I tried to wake from sleep around 1:27 in the logs, and it actually let me boot up and log on around 1:53. To give you an idea of what I was doing to cause these
logs.
MacPro 12 Core is going into sleep mode (so it seems) and becomes unresponsive requiring a hard reboot by holding the power button. Did this on a new user account I created, then it did it in Recovery Mode while using Disk Utility to repair the drives. I was about to try reinstalling OS X but it seems that this maybe a hardware problem if it happened in Recovery mode. Is my thinking right, or could it still be software? Trying to run Hardware test (D on startup) but can't get it to work so far.

I know this is not healthy and I would like to stop it doing this as soon as possible. It is connected via firewire 800 and is a western digital 250 gig my book pro if that makes any difference. I close the lid of my laptop with it still on and connected and everything is supposed to sleep. It used to work fine, I would open the lid and everything would wake up and I could do what I was doing before with no error messages and the hard drive would still be mounted on the desktop.
View 7 Replies View RelatedI'm on an early 2008 mac pro - used to be on a Powerbook G4. I have a 300 GB LaCie d2 Extreme external HD connected via firewire 800. Both are in 10.5.2. While on my powerbook, the drive behaved normally - fell asleep after no use, then awakened when I needed to access something. On my new mac pro, the drive behaves strangely. I only use it for backup, so it's only accessed once a day. The rest of the time I do not use it. When it's not in use, the drive sporadically wakes and sleeps. I've tried to pinpoint the cause to no avail.
I've tried all the usual suspects: browsing the forums, checking the "hard disk sleep" preference in energy saver, switching the firewire 800 cable with usb and firewire 400, watching activity monitor to see if there's a program accessing the drive (haven't found anything, but that doesn't mean it's not there). None of it works.
When my computer goes to sleep it will not wake up, and I have to shut down using the power button on the back and then restart. I called support and they advised me that this only happened when the computer went to sleep on it's opwn but not when you manually put it to sleep, But that proved not to be true. It will not wake up under either situation? The support persontold me to logonto applke and re-install the sytem software which I have done but that did not cure the problem either. I have my preference set to never sleep. I am ar]t a loss as to what to do now as when it goes to sleep or I put it to sleep i sometimes will not start up even after shutting down and restarting.I am on 10.7.2?

My iMac won't start up, or wake from sleep. I've tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on, you can hear the fan run, but the display stays dark.Â

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.

cant wake up imac from sleep after lion upgrade
Info:iMac, Mac OS X (10.7.3)
Ever since I bought and downloaded OS Lion, whenever I put my mac to sleep or it goes to sleep on its own it occasionally won't wake up from sleep. It has to be manually rebooted. Is anyone familiar with this problem. Apple must know about it by now. I'm not lugging my 27" iMac into the apple store to have them look at it unless it won't reboot. Hoping it doesn't come to that...anyone familiar with this or have ideas on how to fix it? I don't know if it's a 3rd party software issue or just the OS.

For some unknown reason I will put my mac to sleep and at sometimes it will wake up without any command to wake up - why this happens and how to correct it?

My screen on my 2 week old iMac comes up pixelated leaving square trails mimicking the movement of the mouse. I have had consultations twice with Apple support junior team members, looking forward to a senior team member reviewing my case. It looks like some sort of eraser wiping the blank dark screen revealing the login screen underneath.
Oh by the way my first iMac was sent back due to dead pixels, how unusual is that?

View 2 Replies View RelatedI just purchased a set of Mushkin Apple 8GB (2x4GB) DDR3 1333MHz SODIMM 9-9-9-24 (976647A) RAM for my mid 2011 27" iMac and everything ran great for a few days. I was able to sleep and wake the machine with no problems. Last night I was doing some graphic intensive work on my machine and when I had finished, the fans were still running high but I was going to bed so I put the machine to sleep. Normally the fans would stop at this point but they kept running. I assumed the machine was still hot so it was just cooling after sleeping. The next morning the machine would not wake. I had to do a hard reset to get it to boot up again I tried resetting the SMC and PRAM but it still doesn't wake from sleep. Am I have issues with my RAM?

I'm using an iMac (late 2011) with 10.7.3. I'm doing things on the computer or some process is going on when the screen instantly goes black (no dimming first). If a video was playing, I can still hear it playing, but pushing keys on the keyboard or mouse or pad does nothing to wake the screen. Sometimes pushing the power button a number of times will get the screen to come on, sometimes it won't. When the screen goes black, if an external drive was running and then stops, I can sometimes get the screen to come to live. Sometimes this black screen happens when I'm burning a DVD; when the DVD is finished, I can bring the screen to life. I thought one of my two external drives was bad, so I disconnected it. That seemed to help (though verifying the disk revealed no problems). But a few minutes ago, the screen instantly went black again; no dimming first. There have been times I thought this was associated with a new bit of software, but then it returns even after I delete the suspect software. Sometimes I have to use the power button to shut down the iMac then restart it. Once, I had to unplug and replug the iMac before I could get the computer to respond and the screen to return to life. I don't know if this is a hardware problem (internal or external), a software problem, or some combination...or something I haven't thought of, at all.

My iMac is set up wireless. Every time it's allowed to go in sleep mode, it loses wireless connectivity. Then, when I wake it up, I must go to System preferences, Network and request it to reconnect to my home wireless network. It always does this successfully, but it's quite annoying that it seems unable to achieve this on it's own. My iPad 2 and kindle can do this, why not my iMac?

When I need to go somewhere or just eat lunch, I put my iMac to sleep. After that, when I come back to wake it back up, it stays black.

View 2 Replies View RelatedCourtesy of jjahshik32, in this thread; A possible resolution has hopefully been found for us users affected by the notorious Mac Pro RAW (Reboot after Wake) problem.
For some users (myself included), the RAW problem seems to appear consistently after running a virtual machine session (Parallels or VMware Fusion, thus far) prior to putting the machine to sleep.
I did the following to test my MP. Can you do something similar and give us your results?
I frequently have to Force Quit my applications - both Microsoft Office apps and Adobe Creative Suite apps. I have an iMac running 10.6.8, connected to a Microsoft 2003 server (the 2008 server works even worse for the iMac connection). I also frequently lose the server connection and have to re-boot to get it back. Re-booting involves pushing the Power button Off, then On because the menu commands don't work.
I have NO issues with the Internet connection - it remains strong throughout. I'm wondering if upgrading to Lion will increase the stability. To do that, I would also have to upgrade my Adobe CS software from CS4 to CS6, and expensive proposition with no guarantee it will resolve these issues. (Many of the Apple techs I called pointed their fingers at the Microsft server.) Is any of this curable? If so, what is the cure?

I have an intel based mac pro running tiger. When it falls asleep if it's asleep for an extended period of time...say 45 minutes or longer, it won't wake up. I have to manually power it down. If it's asleep for less than 45 minutes it wakes up fine.

I have resolved my MacPro sleep issue by removing the Seagate 320GB stock drive. For whatever reason, if that drive is plugged in, it reboots my MacPro when waking from sleep. I had setup 2 WD 500GB drives in RAID 0 as my boot volume and this was configured with Windows XP Pro for other uses.

And my computer went into sleep mode and when I plugged it back in I had to do a manual reboot because the mouse wouldn't move.. So, I turned it back on let it die to see if it would happen again, and then the computer didn't even go to sleep mode.. What is going on? What should I do?
