MacBook Pro :: Why Does It Randomly Go To Sleep
Mar 21, 2012
I just recently noticed that in the middle of doing normal things on my MacBook Pro, it goes to sleep randomly. I have the 2.4ghz 13" 2010 model. It happened twice so far within a 10 minute period. It has happened while charging through the AC adapter. It wakes up fine like usual, and when i close the lid and open it up, it actually wakes up faster than normal. I'm wondering if i should contact apple, or bestbuy (i have a 4 year warranty there)

iMac (24 inch Early 2009, 2.93 GHz Core 2 Duo, Lion 10.7.3) randomly goes sleep. No hot corners, never sleep setting. It seems it goes to sleep more often when CPU is busy and graphic intensive jobs running (videos, gaming). I cleaned up air ways by vaccume, but it did not help.
Temp monitor showed
CPU 55C
power supply 95C
northbridge 89C
graphic processer goes up to 86C
when it went to sleep for no apparent reason./private/var/log/kernel.log says "Previous Sleep Cause: -100"

My MacBook Pro has been waking up from sleep at some of the most random times. Usually it will wake up about 5 minutes after I put it to sleep, and if I'm lucky it will stay to sleep when I try again. Sometimes it will even wake up 30 or 45 minutes after I put it to sleep. Currently, I have it connected to an external display with the laptop screen closed at all times. It is running a fresh install of Snow Leopard with barely any apps installed yet (mainly just iWork and Microsoft Offiice). I was having the same problem when I was running Leopard, thats why I did a fresh install. So this eliminates a software issue.
This has been happening for a few months now, but it has just started to become a problem for me. When I was running Leopard I did not have an external display. It was waking up at random times without anything connected to it (no display, USB, or MagSafe connected). I would be sitting next to my Mac, and all of a sudden, I hear the Superdrive wake up sound. I searched and found a thread similar to this, but hopefully it will not have the same solution as the members of the following thread had: "I had this problem with my Macbook. The fix was a logic board replacement." [URL] I have also attached a screenshot of my system.log in Console. I opened up console as soon as my MBP woke by itself. Hopefully someone here will have some idea what all the stuff in console means or maybe be able to narrow down the problem.

I've tried all sorts of sleep methods: lid, button, start menu (bootcamp) and even on mac osx. However, it will randomly wake at times which makes it frustrating because I don't want to always shut off my laptop. Anyone have this issue?

So over the past week I've been having issues with my Macbook randomly sleeping while I'm just sitting here browsing, typing, etc. I reset the SCM already and it didn't help. I checked the console because I figured SOMETHING had to be the issue. Well, I've got the same error twice now... Here's what it is:
12/15/10 10:01:05 PMkernelAirPort: Link Down on en1. Reason 8 (Disassociated because station leaving).

As far as I can see, the AppleYukon is an ethernet driver, but I'm not using ethernet at all. Is this also the driver for the Airport because that seems to be where the issue is coming from. I'm using a newer Linksys router with WPA2 security.

Since installing Snow Leopard, I have noticed that my Mac will wake randomly. It does not happen all the time, but it does a lot. I have tried to reset the PRAM and it did not help. The "Wake for network access" option in Energy Saver is unchecked. Any ideas?

So, I have a late 2011 MBP 2GH i7, OSX 10.9.3. 500GB HD 16 BG 1600 Mhz DDR3.
The problems started a while ago when the computer started freezing at random times. The mouse would move and there was no "pinwheel" but the computer was unresponsive. When I closed the screen the power was still on and the screen did not shut off. The only way to reset the computer was to hold the power button and do a hard reset. I don't remember if I replaced the RAM from 4BG to 8GB Crucial Memory before or after the computer started freezing, either way, shortly after or around the time when I replaced the ram the hard drive also failed.
I replaced the HD with I believe a Seagate hybrid drive with a small solid state segment. This whole time the computer is still freezing and now since I have a hybrid drive the Apple store can't support because it's not factory specs and MacMall here in Santa Monica can't find anything wrong with the hardware or software after running all of their tests.
At this time I have a feeling it is the ram so I purchase a new 16GB Crucial RAM. Everything is great till it yet once again freezes in the same way as before BUT!! Now if the computer sleeps because the battery run's low, when I plug it in and the computer reboots (grey opaque screen with the vertical lines as the bottom) it starts beeping 3 times. I hard reset via the power button and the computer boots up as normal (although a little slower).

My MBP sometimes wakes up from sleep for no apparent reason. I have it set up in a closed lid/external monitor mode, with a bluetooth keyboard and a wireless usb mouse. To make sure it's not USB activity, I unplugged all USB devices, and switched the USB mouse off. Also made sure "wakeup on ethernet access" is disabled in system prefs, and software update is turned off. Looking at the console, it woke up with a reason:
Wake reason = EHC2 OHC2
Do you know what that is?
Below is a system.log snapshot and console messages when it woke up. Any ideas about what caused it?

i have an imac g5 that has been falling into sleep randomly at times. the first time this happened was when i tried playing the Nanosaurs game that came with the computer. i played for 10 or 15 minutes before it went into sleep mode, and then when i woke it up and tried playing again it would fall back into sleep right away. i havent used that game recently, but it has also fell into sleep while using the dvd rippng program handbrake. it has also fallen into sleep while running other programs, though i do not specifically remember which. after it falls asleep, and after i wake it back up, it often falls right back into sleep mode and i need to close most programs to get it to stay awake. it came with 256 mem and i added another 512 months ago. i dont know if that has anything to do with it but thats the only mod ive made so the rest is just stock.

My iMac is waking up from sleep in the middle of the night. The only clue to what is going on is that is says the wireless keyboard has lost connection.

My mid-2014 15" Macbook Pro randomly "loses" its retina display at the top menu (becomes pixel-y), where the battery, sound, and wifi logos are (on the top right side of the screen). A restart fixes the issue, but I want to know if this is an issue that can be fixed?

I leave my Air on pretty much all the time, and put it to sleep while moving around etc. Sleeping it disconnect the Airport connection - which if very annoying. At a desk I've just been dimming the display all the way off in order to keep my connection.
However, I recently noticed that by setting a "sleep display" hot corner, my network connection is maintained.
I have 2 questions:
1) Is sleep display equivalent (functionally) to simply dimming the display all the way down?
2) Is there a way to either set up a shortcut to sleep the display (other than a hot corner) and/or set it so that only the DISPLAY sleeps after 'x' minutes?

I set the MBP to sleep in 10 min through the Energy Saver pref with the option to sleep the hdds. When it's about to sleep the screen dims, then turns black, then the sleep light comes on but does not blink no matter how long I leave it. The blinking only happens when I close the lid or when I select the Sleep option under the Apple logo. Is that normal behavior?

I have a macbook pro 13" early 2011 and I'm se as shown in the pictures (since i upgraded to os x yosemite) . It happens after display sleep or computer sleep on login not on boot up .I've noticed that i run out of ram when the problem appears (only 15MB RAM available out of 4GB), though i doesn't happen every time . I've talked to service and told me its either motherboard replacement or because the ram isn't enough (gpu shares with main ram) so maybe i should try upgrading ram. URL....

I have torrents going all the time. If the computer goes to sleep, the internet disconnects, so they stop. Display sleep wouldn't disconnect though. Is it OK to have computer sleep on "never" but keep display on "15 minutes"? I don't usually even leave the computer on overnight.

i tried mroogle and search but i couldn't find exactly what i was looking for and i know this community knows it all.
i am trying to prevent my new 2010 macbook pro from going to sleep when the lid in closed. i know there are programs that do this but they keep the display on as well. I wanted to know if there is a program that does it and has the option of turning off display. i am running snow leopard 10.6

Recently I've started connecting my 2.5GHz Intel Core 2 Duo (pre-unibody) Macbook Pro 17" to an external monitor (via DVI).
Since then my computer goes into Safe Sleep instead of Sleep (it's plugged into power).
This is an annoyance I'd rather avoid because even if all programs relaunch:I have to wait for them to launch (longer)Programs like Excel seem to have been quit in an unorthodox fashion: when it starts back up I get an error notice that it was shutdown inappropriately & the doc which reopens is a rescued version of the doc I had open before the safe sleep.

I've had my Macbook Pro since December 2007 and only today I've noticed it suddenly getting hot when doing nothing but browsing forums on Safari, smcFanControl said it was up to a shocking 90 degrees Celcius. At first I just ignored it but it happened again just now but this time only went up to 75 degrees Celcius.

While surfing safari my macbook pro will randomly start highlighting wherever I move my cursor. It happens randomly and it is annoying because I can not get it to stop and it refuses to click on things because the text icon is displayed as it is in highlighting mode. I was wondering what is causing this and how I can stop it?

The issues are random slowdowns and lots of beachballs since yesterday.
At the moment I am running iTunes, Safari, Adium & Skype only.
Might add that it's Safari 4Beta and also the Skype beta.

I'm hoping for some kind of insight on a phantom random shut off issue I'm having. I have a 2007 2.2ghz MacBook Pro running Snow Leopard and upgraded to 4GB ram. Within the last month, it has started to randomly power off. At first it only happened when I closed the lid and it went into sleep, but when I would arrive at school it would have shutdown on the trip. In the middle of this, I also replaced the battery. The day I put the new battery in, the thing freaked out. It powered off randomly while I was working. I was in the middle of the first battery calibration so I thought it might be a battery issue. When I tried to power back on, it would start to load the desktop and then power off again. I couldn't get it through a full boot cycle. I tried various configs of old battery, new battery, with power, without power cord and nothing seemed to work. Reset the SMC and PRAM as well to no avail. The longer I let it sit the longer I could work prior to power failure. So I assumed it was FUBAR and walked away.
Next morning called apple care and of course, things seemed fine. However, 1.5hours in, shuts off. Crap, Apple Care said go to Genius bar get it checked. Three days at Genius bar, full hardware and stress test and everything passed flying colors. I thought maybe it was a naughty little gnome who had decided to move on and torment some other guy. 3 days go by no problem, then today during sleep it powered off again. Then tonight, twice while working with powercord attached (one time losing about an hours worth of Excel work, which was a nice bonus).
Since everything checked out fine, I'm struggling with what to tell Apple if I take it back for repair. I need the laptop, but trying to work expecting impending doom when it randomly decides to shutdown sucks. I have apple care, but if they can't find any issues then it doesn't do me any good.
Any suggestions? Is it worth trying to do a clean install or look at some kind of software issue? Has anyone else dealt with this kind of issue?

my macbook pro has started to just cut out randomly. I have had this with an expanding battery and haven't had the money to replace it yet, but I don't know if this is part of the issue. When my computer cuts out, it is as though the power cable has been pulled out and the whole system just shuts off in an instant. I know that the power cable has definitely not come out, though.
