I've set it to 1 minute but only the monitor will turn off. Manually putting the computer to sleep work's fine.

May 15, 2010I am new to this forum, but hoping I can get an answer here. When placing my Macbook Pro in sleep mode by closing the lid, it goes into sleep mode, but immediately turns back on (with the lid closed), then after a short time goes back into sleep mode and then immediately turns back on. It keeps cycling like this. Any clues to why it will not stay in the sleep mode?

OS X :: Why Does My G-5 Shut Down My Computer In Sleep Mode
Nov 14, 2008Could someone please explain to me why my computer is shutting down in sleep-mode. In addition, when it happens, the fan goes into hyperblow, which doesn't make sense because it would not be operating if the system were completely shut down. It acts like it is shut down but won't respond or wake up, etc. I re-loaded my system software per the Mac Store Genius' advice, but that didn't work. Is it possible that my power supply is going?

View 5 Replies View RelatedSoftware :: System Not Exiting Sleep Mode / Kicks Back Into Sleep Mode
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 :: Computer Crashes And Loses Hard Drive When Goes Into Sleep Mode?
Dec 21, 2009I just had the original 300 GB hard drive fail in my aluminum 24" inch iMac running the latest update of Leopard. I wasn't able to save it using diskwarrior (diskwarrior said it was some sort of mechanical failure) but I was able to recover most of the data from it by booting from an external hard-drive.
So I went out and purchased a brand new Western Digital Caviar Black 1TB drive. The install went fine, it found the drive partitioned it and installed Leopard successful. Then is crashed and disappeared when I left it alone to run all the software updates. I came back and the computer was stuck on "Restart Required" after downloading all the updates. I went to hit restart now, and the system just hanged, wouldn't do anything. So I hard powered down the system and restarted it. It came up with nothing, just stuck on the White Screen of Death. So I plugged the external drive back in and booted from it. Mac OSX couldn't find the drive and diskwarrior would crash if I tried to run it. I tried to boot up from the OSX start-up disk and it couldn't find the drive either.
So I took the case apart and made sure all the connections were solid and the drive was mounted correctly. Everything looked fine so I plugged it in and it started up fine. Finished the updates and the iMac ran great.
So I thought maybe it was overheating, so I've installed smcfancontrol and started to monitor the temp of the drive. I also took the mac apart again and sucked out any dust in the fans or vents. The drive never goes over a 105 F, so it doesn't seem to be overheating.
However, this is where the problem is consistent: everytime the iMac goes into sleep mode, it crashes and the iMac is unable to find the hard-drive again. Unless I unplug it completely for 5 minutes or so. Once I unplug it, it finds the drive and operates like a champ.
I think maybe there's an issue powering the drive back on? Anyone have any ideas?
And my follow up posting later that day:
Quote:
So I ran some tests just to see if was an overheat issue, hard drive malfunction, or sleep issue. I decided to start encoding a video, pulled up Word, Power Point, Excel, started downloading all 6000 mail messages off my server (I never delete my e-mail :-/), also started installing iLife 09, and pulled up a bunch of webpages in Firefox with multiple tabs.
However, I shut off all sleep mode options on the hard drive. I let it run for an hour and came back. Everything is fine, hard drive isn't locked up and smcfancontrol shows the hard drive running pretty hot (115 degrees) but not so hot I'm worried. So it's definitely something to do the hard drives going into sleep mode and not powering back on. It's also weird that I have to leave the computer completely unplugged for 10-15 minutes before the drive is recognized again.
So turning off sleep seems to be my work-around, however, this shouldn't be a long term solution. I'm worried that there is a bigger issue with the iMac, but I'm not sure what would cause this. I've been a PC guy for years, this was my first Mac, and honestly I don't know enough about the inner workings to narrow this down. I would assume this would have to do with the motherboard in some way? But I'm not sure how you would even test it.
MacBook Pro :: After Sleep Mode Computer Sometimes Doesn't Recognize Wireless Connection
Jun 22, 2012After using my MacBook Pro I close the laptop and it goes to sleep. Later when I return to it and open it, sometimes it can't find the network. The computer is able to see that I have an Apple Network available, but it won't connect.Sometimes when I try to connect, it gives me a timeout. How I fix it is to walk over to the router and unplug it and plug it back in. After I get the green light again, I go to the Apple Network and it works.

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.
