Dec 29, 2009As 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 :: Goes Right Back To Sleep After Wake - Up
Aug 13, 2010I have an older iMac (MA589LL) that I recently upgraded to 4GB and Snow Leopard which is running beautifully. I do have an issue with it though, and it's been occurring for a while: Whenever the machine goes to sleep and I wake it up, the monitor turns on just fine but after about 5 seconds it goes back to sleep. I have to repeat this about 3 times and then it is fine. It's an annoying issue but not a deal breaker as I can just turn it off. I searched for sleep issues/turn off issues and have not found anything.
NOTE: Issue occurred before the upgrades. I've also tried resetting the PRAM and NVRAM. I have also used different keyboards/mouses.

View 3 Replies View RelatedIntel Mac :: 2011 Screen Unexpectedly Goes Black (to Sleep), Won't Wake
Feb 19, 2012I'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.

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.

Intel Mac :: Would Not Wake Up From Sleep Mode
May 5, 2012My 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.

Intel Mac :: Won't Wake From Sleep Mode
May 28, 2012Computer 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.

Apr 20, 2012When I close then open the lid on my MacBook, it will not wake up from sleep mode. I have to reboot by holding down the power button for 10 sec. When it restarts, it takes a long time to get past the gray screen with the apple logo. I also have this same problem when it goes into sleep mode, when left idle. I have since changed the settings so it will not go into sleep mode when idle in system preferences. I have reset PRAM and SMC, but the problem still persists.

Power Mac G5 :: Wake Up From Sleep Mode Causing Crashes
Oct 20, 2007I'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

Intel Mac :: Loses Wireless Connection After Wake Up From Sleep Mode
Feb 23, 2012My 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?

Software :: Middle Of Using An App, Browsing Web Page - System Into Sleep Mode And Will Not Wake?
Jun 18, 2009I can be in the middle of using an application, browsing a web-page, or basically any type of function when it will put itself into sleep mode. When this happens, I cannot get it to "wake up". I have to disconnect it from the power source, turn it over and remove the battery, wait a few seconds, then hit the power button, put the battery back in, then restart it. This is the only way I have found that will get it to come back to life. I don't like doing it, but I really don't see what other options I have.

OS X Yosemite :: Keyboard / Trackpad Stop Working After Sleep Mode?
Dec 3, 2014After a few hours of uptime, certain keys on my keyboard stop working and I have to reboot: both command keys and the zero key. Sometimes, after the computer has been in sleep a long time, the keyboard and mouse don't respond at all. I can get the computer to wake up again by pressing the power key, but the mouse and keyboard don't respond, so I can't do anything except hard boot. This problem first appeared after the update to 10.10.1. (I'm dealing with it right now, so I'm getting the '0' through the keyboard viewer, but there's no way to access that from the password screen.)
