MacBook starts and instantly enters sleep mode
In the past few days I've been experiencing a reoccurring problem with my macbook pro. I press the power button, hear the startup of the drive, and then sometimes the display will turn on for a second(mostly stays off), and then enters sleep mode instantly. I can not get on my macbook unless I turn it on and let it sit for 15-20 minutes, then MAYBE the display will activate. Please help.
Do you hear a chime at startup? How do you know it is entering sleep mode and not turning off? Does the cursor move on the screen? Here is something from another user's experience:
I had the same issue with my 2008 iMac and Apple support walked me through the fix yesterday...
1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).
Apparently it's an issue with an automatic update that never quite got past the login screen.

Macbook - Unplug AC power and Mac enters sleep mode
I am using a Macbook with a Dell 24 inch monitor, external keyboard and mouse. The lid is usually closed and I am familiar with the best practices how to use sleep mode.
I have now found that, in the above scenario, unplugging the power cord puts the Mac to sleep immediately. The batter is charged at 99% or better.
The reason why I want to unplug: let it drain to condition the battery according to Apple recommendations.
I am aware of the workaround: disconnect external peripherals, let Mac run on battery until it is drained (I like to think that the peripherals perhaps are part of the issue here).
I was simply wondering if putting the Mac to sleep when AC power is disconnected is a feature, or if anyone here has a suggestion. This has not previously happened to me when I used the Mac without the monitor/keyboard.
Thanks!It requires the power adapter when using an external display. The electronics to drive a DVI port uses some power, and they assume power must be available if you have some place to plug in the external display, so they don't allow it to run an external display on battery only. To drain the battery, disconnect the external display, and run it at full brightness with the llid open and Energy Saving system preference set to never sleep the drive, display, or computer, and to run for maximum speed. You only have to calibrate a battery once. NiCads needed conditioning. Lithium-ion don't. Under some conditions you might extend the life slightly, but full discharges reduce life, so getting it just right is unlikely.

MacBook Pro 13" Retina enters Sleep Mode again after a few seconds
Hello!
Well, like the title already says, my MacBook Pro 13" Retina just entered into Sleep Mode again after I exited it. It took a few seconds, during which I could do stuff on it, like write on Messages.app and browse the internet. Then the screen just went black, and after I pressed a few buttons, the login-screen appeared again.
Any idea on what the source of this could be? Is it just a settings-goof (which I still have on default), or is there something major behind it? ^^" Mind you, I'm running it from the battery, it's not plugged into a power supply socket.
I have version 10.8.4 running.Try resetting the SMC

Macbook Pro does not enter sleep mode anymore
Hey guys!
I have found several threads relating to this topic, none of them offering a solution, which worked for me.
I recently updated from Tiger to Leopard (clean install), since then my computer won´t go to sleep automatically. I can put it to sleep manually or close the lid, it will sleep and wake up without any problems.
However, it will not go into *sleep mode automatically* when inactive. The display will sleep, with the sleep light constantly on and not pulsing, fans keep going.
What i have tried so far:
- closing all applications
- disable all network sharing
- SMC reset
- PRAM reset
None of those did work out for me.
I really do hope someone can help me out here, as i don´t want my computer to burn calories 24/7.
Thanks in advance

how do i check for those processes? there are a lot of processes running, what are haxies?
You would set the time to sleep to a short time and simply watch the top processes to see if a new one pops up.
Haxies are tools that modify the OS directly. TinkerTools is one of them. They are safe to use, but sometimes problematic.
i checked for the login items:
iCalAlarmScheduler and EyeTV Helper are activated.
Aha!
I would remove both of them, but I think the EyeTV Helper is the problem.
Some have reported the EyeTV Helper being a problem in waking the computer up at odd hours, but it might also affect sleep. You remove them with the little ( - ) sign at the bottom, not the "hide" checkbox with does nothing important.
Cmd-Opt-Eject puts my macbook to sleep, yes.
Just checking that a force-sleep works. I use it all the time. -
Why is my MacBook Air slow to enter sleep mode?
My partner's goes to sleep instantly, mine takes about 30 seconds - most obvious difference is that I have MS Office installed (but not running). I've tried resetting SMC but no benefit. Help would be much appreciated.
No, nothing whatsoever. Have just upgraded to the latest OS (10.8.2? Don't have the MacBook to hand, but was latest a few hours ago :-D), but hasn't helped. Presumably some process is running that takes a while to close - but wary of closing down processes without knowing for sure what they're doing!
In the *past* I had an external DVD drive attached - used it when installing MS Office - but hasn't been connected for months, and MacBook has been switched on and off and restarted several times since.
Grateful for any help you can give!
cheers,

Alo, my Macbook pro i7 2 GHz Intel Core i7 (early 2011) will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?
There is no output from that command line? Maybe the pid changed.
I'll repeat what I am trying to find out...
1. You do a pmset -g on the terminal.
2. The output from that pmset should have a line that says "sleep 0 (imposed by n)" where n is some number.
3. The ps ax | grep n is supposed to display what the process associated with n is.
It's the output from step 3 that should indicate what is causing you not to sleep.
But speaking of sleep, that's where I am going. -

Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software. -
My macbook boots up and only stays on for 30sec and goes into sleep mode
My macbook boots up and only stays on for 30sec and goes into sleep mode! Any suggestions as to why this might be happening? Thanks....
I assume you have checked your sleep settings in System Preferences>Energy saver
I also assume this has just happened recently and spontaneously, not after installing any particular hardware or software or you would probably have mentioned it...if anything new has been added recently, obviously just remove it!
It could be the battery - have your tried it just on mains? If it's a pre unibody MacBook try it without the battery at all. This could happen if you have a non-Apple (cheap Chinese) replacement battery.
Try NVRAM, PRAM & SMC resets (Google if you don't know how)
Try booting from the install media and repairing or reinstalling OS X. (Back up first!)
Just out of interest if you boot from a DVD or go into Open Firmware or Boot Select modes, does it still sleep after 30 seconds or is it just in OS X? -
Why is there a clicking sound when I close the cover and enter sleep mode?
why is there a clicking sound when I close the cover and enter sleep mode?
Hi katesvca,
I too have an iPad smart cover, and all that clicking sound is is basically the standard lock sound for iOS. The Smart cover is equipped with magnets inside, and the iPad is also equipped with magnets, and when those magnets are closed together the iPad goes to sleep.
I hope this answers your question. -
Mac mini keeps entering sleep mode
Hi. I have a Mac mini that has this annoying problem where it keeps
wanting to enter sleep mode. This problem seemed intermittent at first.
What I notice is that my mini would enter sleep mode whenever I try to
encode mp3. This seems reproducible. When it enters sleep mode,
I can wake it up by pressing the power button. However, it goes back
in sleep mode after a couple seconds after it wakes up. The only way
I can get it out of sleep mode is to quit iTunes and eject the audio
CD.
Things I've tried:
Energy Saver settings: Computer sleeps after 3 hours inactivity,
display sleeps after 3 hours inactivity, unchecked "Put hard disk(s)
to sleep when possible". I tried disabling energy save. No luck.
I also tried to uncheck "Allow Nap" box in the Processor settings.
However, it always checks this after a reboot.
If I insert a DVD movie, I can watch it w/o any interruption.
Anyone else seen this problem? Thanks in advance.
JimHi Carl. I was unable to find com.apple.AutoWake.plist in my
system. Deleting com.apple.PowerManagement.plist didn't
help.
I decided to try your open firmware instructions. I like the
boot loader. It reminds me of the Sun's boot monitor.
I did the reset-nvram, set-defaults, reset-all. It didn't
help though.
I don't think it is my power supply, either. The reason why I
don't think this is the problem is I can watch DVD and listen
to audio CD just fine. My sleep problem would only occur
when I try to rip an audio CD. I can assure you that I draw
plenty of power just playing a DVD movie.
My guess is I have a power management configuration
issue or a hardware problem. Since this has a Unix core
underneath, I started poking around in the usual places
for log files. I found the familiar /var/log and stumbled
on system.log. Looking at the file, I found something
that caught my eye.
Aug 17 01:06:19 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Doing a 'grep overtemp system.log', I got the following:
Aug 17 01:04:13 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:04:37 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:04:56 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:05:37 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:05:51 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:06:00 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:06:13 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:06:19 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
If you look at the time stamp, you'll see that each event
is only a few seconds apart. This matches with what
I was seeing. Machine goes to sleep. I press the power
button and it wakes up and goes back to sleep. One
big endless cycle. The only way I managed to get out
of it is to quit iTunes and to eject the CD.
Yes, I did install the Xcode 2 development kit that came
with the Mini MAC OSX setup. I eventually want to write
software for the Mac. So, I most likely installed the
CHUD tools package that you had mentioned.
I think the equivalent command line command for
disabling the nap feature is 'hwprefs -v cpu_nap=false'.
When I do that, I get the overtemp event and my mini
goes to sleep. Zzz.
In any case, my mini seems to be detecting false overtemp
condition. Either I have a bad temp sensor or my power
management overtemp threshold is set way too low. It's
possible encoding audio CDs is enough to heat up the
PPC core, but it happens way too fast. I'm thinking my
temperature sensors are not set correctly. If anyone has
schematics for the mini, it would most likely be a Dallas
temp sensor chip. I'm not ready to open up my mini yet
since it is still under warranty. I'll take it in the Apple
store in Walnut Creek this weekend.
Anyway, thank you guys for all your help. I found my
experience on this forum to be quite pleasant. People
here are very helpful.

Mac Pro unexpectedly enters sleep mode
Ok so I installed Leopard last weekend on my Mac Pro and all initially went well with the install. After installation was done, software update appeared and stated I had approximately 4 downloads to install. So I had done this and prepared to reboot. Before rebooting, a window appeared stating that it needed to update the Boot cache. So I clicked on "OK" and the computer went into its shutdown sequence. When the computer reset, I noticed there was no start up chime and the system just sat there with a black screen. I thought perhaps it was updating the boot cache and it may take a while to finish. So I went afk for about an hour and came back. Still nothing. This is when I knew there was something seriously wrong with my system.
After speaking with Apple support and trying several things to get it to boot, the support rep stated that it will need to go into the shop for repairs. I had taken it to an authorized service center and they diagnosed the problem as a bad logic board. They had replaced this and had ran their diagnostic tools on it to make sure it was running normally. They kept it overnight and ran Apple Service diagnostics in a repeating loop on the system. They had also cold booted the system 30+ times per the work order.
After I brought it home and booted it, everything was seemingly running fine. Then I received a page from work (I'm a support rep) which required me to boot into Windows using Boot Camp to solve a client's problem. After I had done this, I booted Leopard back up and was playing around in it for a few minutes to check out some of the new features. I had then ran World of Warcraft to play a bit and to check out the performance increase in Leopard. After about 5 minutes of playing, my system unexpectedly entered sleep mode. Obviously I was confused so I had brought it out of sleep mode by hitting the enter key. The system came back for about 2 seconds and immediately went back into sleep mode again. This happened about 4 or 5 times before I finally shut the system down.
The first thing I did after reboot is to check the energy saver options. Both hard drive and monitor energy options were set to "Never". I then checked for software updates. There was both an SMC firmware update and a Boot Camp EFI(?) firmware update. I had done the SMC firmware update first and then after successfully updating this, I had done the Boot Camp firmware update. After reboot, the system went into sleep mode on its own approximately 5 minutes after reboot. This time I had made sure NOT to run my game as I had a suspicion that this could be causing the problem. It entered sleep mode anyway unexpectedly. After waking it up again by hitting the enter key, the desktop appeared again for about 2 seconds before going right back into sleep mode. I called the service center again and they said I would have to bring it in for them to look at. Needless to say, I am NOT very pleased.
Has anyone ever heard of anything like this happening with a Mac Pro? I had never had any problems when I was running Tiger with any application, not even my game. The service rep where I took it said it was just bad timing that the logic board went during my OS upgrade and that the two had nothing to do with each other. My brother has a Mac Pro as well and he had upgraded to Leopard. Of course his computer works fine where mine is a sleeping fool. Does anyone have any ideas or theories as to what could be causing this? More importantly, does anyone have any suggestions on how I might be able to fix this on my own? If you could please let me know, I would appreciate it. Thank you in advance for your time.Wow, who are you dealing with? The first time my logic board was replaced, the techs never bothered with looking at anything else as being the problem. However, when I pointed out the power supply fan problem, they focused on that being the cause of the problem and fixed just that. I was somewhat concerned as I know some of these techs do not look at other parts of the machine as potential problem causers. I was afraid that I would hook up my system only to experience the same problem as before. Luckily, that was not the case.
I am glad that your system appears to have the same problem as mine did. I would suggest that if you take it back to them again for a fan fix to have them run the system for about an hour after replacing it. They should be opening apps, checking the iStat widget, etc to try and make it break. If they can't after an hour or so, I think it should be ok.
This whole ordeal makes me question the quality of parts used by Apple. My brother has an iMac G4 where the hard drive died after 2 months of getting it new. Now this issue with mine and yours with the bad logic board and the power supply fan. Who knows how many other customers report hardware related problems? -
IMac beeps once before entering sleep mode
My iMac 24 inch has started to beep once before entereing sleep mode. The LED thinks blinks whilst it is asleep, which I assume is normal. Is this indicative of a hardware fault? I understand that a single beep on startup indicates a ram problem.
If you listen carefully, you may find this beep is
coming from the hard drive, not the speakers (plug
headphones in and find out if it still makes the
beep).
Some hard drives make this beep if they have a
re-positioned write, which is a non-fatal error. You
can usually reformat to re-allocate the block and
stop the error, or you can live with it.//
Hi
Yes you're correct, it doesn't come from speakers. It not makes the same faint beep (rather like a heart monitor blip) when closing down and always after the screen has gone blank. I have noticed that if you put a CD-ROM in the DVD drive and its still spinning when you put it into sleep mode you don't get the sound.

All-in-one 6830 printer Does not enter sleep mode when connected to a phone line
HP staff help. HP all-in-one printer 6830 does not enter sleep mode when conntected to a phone line via 1-Line jack. The Firmware is PNP1CN1521AR. On August 1, 2015, I purchased an HP all-in-one 6830 printer and upgraded to firmware PNP1CN1521AR.When a phone line is connected to 1-Line jack of 6830, the printer will no longer enter sleep mode and the display remains on indefinitly.Removing the phone connection either from the wall outlet or from the printer causes the sleep mode to work correctly again where the control panel display turns off after 5 minutes (or optionally after 10 or 15 minutes).This problem was previously reported by a user and has not been resolved, see:http://h30434.www3.hp.com/t5/Other-Printing-Questions/Sleep-mode-of-Officejet-Pro-6830/td-p/4772182 The user did not receive a resolution to this problem according to the thread.
There seems to be a 6830 printer firmware or hardware problem causing this. HP should be able to confirm this problem on 6830 easily.
Please advise ASAP.
ThanksIt's a regular analog phone line. I've tested it with other phone lines. No difference. I have another all-in-one printer which works fine (goes to sleep mode) when plugged into the same phone line.
The 6830 works ok in other aspects. The only problem is the sleep mode. Any 6830 with the firmware I mentioned should replicate the same result, regardless of anything else. The previous firmware to PNP1CN1521AR also created this problem according to the original report of this problem by another user.
I'm sure there's a bug in the firmware. A subroutine in the firmware monitoring the incoming fax ringing, mistakenly, sees the voltage across the phone jack pins as an event and wakes up the printer instantly even though there's no ringing. As the previous user also suspected, there seems to be an error in the phone line voltage threshold used by the firmware. The present firmware always sees a ringing at the phone line which causes it to never stay in sleep mode. -
I started having this issue a few weeks ago. The monitor no longer enters sleep mode for whatever reason after I turn off my devices connected to it (currently my PC via DVI and my PS4 via HDMI), it turns on and displays a box with "no source signal" and never goes to sleep. Before it displayed a box with "monitor going to sleep" for a few seconds and the panel turned off as the montor entered sleep mode. This is extremely annoying. How do I fix it? What's wrong with it? I already tried a factory reset.

Windows 10 - won't enter sleep mode
So I updated to windows 10 roughly a week ago. I have had sleep issues from day one with it not being able to wake up if it didn't enter sleep mode properly. I ended up just remembering to hit the power button or shut the lid and that was enough to put it into sleep mode and was able to wake it after opening. I saw another user said to update the Bios driver... that was working til a windows update. Two/Three days ago windows had an automatic update and that seemed to cause the problem again. But now I cannot get it into sleep mode at all even with the power button, closing the lid and even going to start and hitting sleep. it turns off the screen and the power light continues to just be on without blinking and the fan keeps running. This computer is only 6 months ago and I am getting frusterated. I will probably go back to 8.1 as having to hard power down the computer can't be good for it everytime I walk away and forget to completely power it down. Does anyone have another solution I can try before I jump ship?
I have installed all updates from Windows Update and all drivers from Toshiba US website. I can't find the Service Station for Windows 10 from Toshiba website. I only found the one for Windows 8.
