Spontaneous forced sleep?

My new (3 months) G4 Powerbook has begun spontaneously going to sleep. It does not appear to be a battery problem. The screen goes dark, the sleep beam begins pulsating. I can power it back up (but sometimes not right away) by depressing the command and option keys, sometimes the power button. When the screen comes back whatever I was working on is still there, though itunes will stop and if I am connnected to the internet (I have a dial-up) it will terminate the connection.
I have been to the nearest Apple store and they checked all the settings and thought they might have solved it. But the problem persists, sporadically, without any discernible pattern. Ideas?

Hi!
I hope this solves your problem, because I have this problem as we speak, and my Mac has finally gone completely unresponsive on me (it hangs on boot after one too many forced resets).
The problem for me has been that the trackpad temperature sensor has been malfunctioning. At times it has been reporting temperatures as low as about -180 degrees C, and at times over 100 degrees C. Whenever the temperature crosses the magic 48 degrees C mark, the OS hibernates spontanously due to an emergency overtemp signal. This can be found if you check the system logs (try using Console found in the Utilities folder).
This spontaneous sleep was completely random, unpredictable, and any amount of time could pass between occurrences. Sometimes I could wake it from sleep, other times I couldn't, and I would force restart it by popping the battery and holding the power button down some 5 seconds. Not exactly a healthy workflow in the daily course of things.
In order to find out how your sensors are behaving, and which one it might be, try searching for some software that monitors this. I don't recall which one I use, but they can be found. This might finally diagnose your problem.
My Mac is still under warranty, but since I first return to Denmark later this month, I have a dead Mac until I return, and submit it for replacement/repair. Frankly, I can't wait a month for a fix... my Mac is my work... and though I have backups, I have no backup computer. I'm not that rich.
So I hope you can diagnose the problem by checking the system logs ... and ultimately monitoring the temperature of the sensors in your Mac. The program I was using could record histories (it made a graph of temp. vs. time) so it became clearly evident what the heck was going on.
Cheers,
Dan

Finder spontaneously force quitting

Hello! About a week ago I updated my 2011 Macbook Pro to Yosemite and had no issues except I noticed that the Finder was constantly "Not Responding" but I was able to access it by going to File->New Finder Window despite this issue. Then last night, my computer slowed down a great deal and I was forced to restart my computer. Upon restarting, I was greeted by a gray screen with a little image of a gray man with a question mark over his face and the words Update Needed in brackets under that. I proceeded to my desktop to find that the icons on the desktop were all flashing as the Finder was spontaneously force quitting and reopening. I could not do anything as the computer was absolutely freaking out so I booted up in Safe Mode. Ran disk permissions, fixed disk permissions. No change upon rebooting normally. So i decided to install a fresh copy of OS X from the Recovery drive. Problem is still persisting. Does anybody have any suggestions for fixing this before I go ahead and do an erase and install from Time Machine? Thank you for your help!

Force sleep without disabling Internet Sharing

Hi,
Now that Mountain Lion includes WPA2 Personal encryption for Internet Sharing over Wireless, I've decided to try using it instead of my Airport Extreme Base Station to shre my internet access with my iPhone and notebook. One of the benefits I hoped to gain was the ability to simply put my Mac mini to sleep to turn off my network when, for example, sleeping or at work. That way I reduce opportunity for unauthorized attempts at access and save energy.
The only flaw appears to be that the Mac mini doesn't want to sleep when Internet Sharing is on. I've tried using the menu item and the keystroke (Option-Command-Eject), but neither will send the Mac to sleep. To get around this, I could simply turn off Internet Sharing when I don't need it; but:
1) This means launching System Preferences and authenticating to the Sharing pane, which is cumbersome and slow
2) Internet Sharing forgets my wifi settings when it's disabled
Does anyone know of a way to force my Mac to sleep even when Internet Sharing is enabled?

Hello Scotch,
I'm working on my MBP 15' late 2011. I use it at school (Wifi network) and at home (Ethernet cable).
I also like to turn on the internet sharing for my iphone as my room is to far from our hotspot @ home... (**** you concrete walls)
But i'm also one of the jerks that abuses his mac by almost never shutting it down and just closing the lid (same as putting it to sleep).
i found out that when i close the lid with the ethernet plugged in (& sharing turned on), my macbook does not sleep. This can be handy, but can be annoying for noises at night.
If you turn off the airport on your computer, or remove the wired internet connection, the internet sharing will stop without changing your pref's.
when you turn it back on, or plug the cable back in; the sharing starts again with the same settings automaticly.
It's not 100% what you're asking for, but it does the job in 2 clicks...
i hope it helped.
Greetings,
Wouter, Belgium.

Imac sleep settings don't work - imac forces sleep

many people seem to have an issue where they can't get their computer to sleep.
i have the opposite problem, i can't prevent it from going to sleep, regardless of all sleep settings, which also closes all open applications.
if i walk away for an hour and come back, i log in, every single app is closed, and i have a blank slate.
apple care has tried everything....
any ideas?

Have a look at this.
System Preferences>Security>Log out after -- minutes of activity. Is that checked?

Forced Sleep, Thermal runaways, and how hot is your cpu?

I've been dealing with a problem for a while on my PowerMac G5 dual 2.7. Under certain conditions is goes to sleep on it's own, usually when under heavy load, but also sometimes after waking up. The problem has gotten progressively worse.
After reading thorough this excellent forum I discover to look for Thermal runaways. Sure enough, the system log confirms that is my problem.
Based on advice I have gleened from here, I have so far tried:
1) Updating the system from the 10.4.3 combo download from the apple site.
2) Resetting the SMU.
3) Replace both of the .plist files for Energy Saver.
4) Run Apple Hardware test. (it showed nothing)
So far the only thing that has worked has been to change the pocessor setting in Energy Saver to "reduced".
While going through this process I downloaded a nifty little program called Temperature Monitor, and I have been running it constantly to keep a decent log.
Yesterday I took my Mac to the Genius bar at my local Apple store. We were unable to replicate the problem in the 15 minutes we had it running, althought it showed about the same temp range as when I've had it running at home for hours. If running (even sleeping) for a couple of hours I can reproduce the problem easily.
Here lies my delimma. My processors seem to be running hot, and CPU B runs about 15 degress hotter than CPU A.
Here's some data (averages are estimated based on weeks of data):
CPU A min temp 90.4 max temp 187.0 average 168
CPU B min temp 95.5 max temp 209.7 average 175
All other temeratures seem to be in line with downloaded data I got from another freeware called ThermographX. The ThermographX data seems to indicate that my processor temps should be in the 90F - 137F range. Mine are clearly in the 155F-190F range, with CPU B always 10-25 degrees hotter than CPU A.
So does anyone know what temp the CPUs should be running at?
One last thing. The data from my system log (see below) appears to give some temps (T_cur=115 >= (T_max:88 + sleepOffset:20). The question is, what do these numbers mean?
Dec 21 18:17:09 tolladays-power-mac-g5 kernel[0]: PowerMac7,3 Thermal Manager: Thermal Runaway Detected: System Will Sleep
Dec 21 18:17:09 tolladays-power-mac-g5 kernel[0]: PM73 T_cur=115 >= (T_max:88 + sleepOffset:20)
G5 Dual 2.7 Mac OS X (10.4.3)

My case was very similar to yours. I came to a solution so simple that it's even funny.
I experienced high temperatures on my Dual Powermac G5 2.5 (late 2004), around 90ºC even when doing simple tasks such as browsing the web. When doing cpu-intensive tasks (such as encoding a video with iDVD) the temperature went up to 105ºC or more, causing the machine to go into sleep mode and writing that "thermal runaway" entry in the logs.
I ran the Apple hardware test (which I recommend you to run if you haven't) and it gave me the following error code:
2STH/1/2: CPU A AD7417 AD1
According to http://docs.info.apple.com/article.html?artnum=86492 there seemed to be a problem with my CPU A thermal sensor.
Since the mere thought of taking my powermac for repair is completely unbearable to me, I bought a new SATA hard disk drive with the purpose of installing OS X from scratch, therefore discarding any software related problems.
When I opened the G5 case I noticed large amounts of dust in front of the CPUs air inflow grid. And that was the cause of my problems. I cleaned the inside of my powermac with a vacuum cleaner, paying special attention to ventilation grids and fans.
I ran the hardware test again and it gave me no errors. Additionally, now my powermac runs at lower temperatures (around 55-60ºC when not doing cpu-intensive tasks) and I haven't had any more thermal runaways.
My solution was very simple and perhaps obvious, but it worked. I hope it helps.

Applescript via command line forces sleep

Weird problem here....any time I try to run an applescript from the command line in Terminal the entire screen goes black and ultimately the computer goes to sleep (glowing light on the Macbook Pro).
Anyone have any thoughts on what's causing this and how I can fix it?
Thanks.

Details on the script would be useful, but you'll probably get a better answer by closing this topic and reposting to the Applescript forum: http://discussions.apple.com/forum.jspa?forumID=724.

Wont wake up after forced sleep when battery dies

I have a new MacBookPro OSX 10.7.2 from the first day the laptop will wakeup from hibernation or sleep after the battery dies.
I try to let the battery cycle fully before plugging in and reguaarly the laptop shutsdown when the battery is low.
When i try to turn it back on it starts the wake up process with indicator bars showing progress, then it stops at about three bars and just beeps indefinatly until i power off the machine when i turn it back on it comes up but ive lost everything i was working on!
very frustrating, why wont it properly wake up after a low battery hibernation??!????

Well the question is when this happened the first time and you lost everything you were working on why did you let it happen the second time or the third or forth and not plug the computer in.
It may be frustrating but there is only one person to blame and that is you. Not Apple and not the computer. As YOU knew exactly what was going to happen but you let it happen anyway.
The true definition of insanity is doing the same things over and over and expecting a different outcome.

Leopard spontaneously awakens from sleep

I have an Intel Mac Pro that's about 3 years old. It worked fine with Tiger. When I upgraded to Leopard, the machine suddenly started awakening spontaneously from sleep, which I finally solved by removing all USB devices, including keyboard and mouse, and tapping the power button to put it to sleep. I don't use Bluetooth devices; they're not reliable and don't work well for me.
Upgrading to Snow Leopard resolved this problem. Now the Mac Pro sleeps and awakens properly.
I just upgraded my wife's Power PC G5 machine to Leopard, and all of a sudden her computer now awakens if there is any movement in the room containing the computer. It never did that before on Tiger. (She also has no Bluetooth devices.) Not surprisingly, she blames me for "breaking" her Mac.
In both scenarios, even the slightest movement in the room was enough to awaken the Macs. My question is, since this appeared only in Leopard and went away in Snow Leopard, is there a Terminal setting that will turn it off?

At this point I think you should get Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files!
Disconnect the USB cable from any UPS so the system doesn't shut down in the middle of the process.
Get Temperature Monitor to see if it's heat related...
http://www.macupdate.com/info.php/id/12381/temperature-monitor
And/or iStat Pro...
http://www.islayer.com/apps/istatpro/
If you have any temps in the 70°C/160°F range, that's likely it.

G5 Tower crashes on sleep after Leopard upgrade

I recently "upgraded" from Tiger (10.4.11) to Leopard (!0.5.8). Now, automatic sleep doesn't work. But worse, when I force sleep, the G5 crashes every time (turbo fans come on) within 5 min of sleep - the machine is unresponsive requiring a forced shut down. I have tried forcing sleep when no apps are running (except the OS). I do not have any antivirus SW. I'm thinking of trying to sleep in safe mode to see whether it's any of the apps that load at startup or as root, but other than that, I'm clueless on what to do since this appears to be an OS issue. Comments and strategies would be very helpful.
BTW, there 54GB of free HDD space, there is 2.6 GB of ram and have recently run DiskWarrior on the HDD in case any of this matters.
John

Nice tech note. I've always tried to decipher what was in those logs. This helps but not in this case. I've copied the crash log that was generated below. Incidentally, I also tried booting back into a Tiger mirrored drive (I will keep them until I'm completely comfortable with the Leopard install, WHICH I'M NOT). Slept and woke as it should. So it's definitely the Leopard install but why? I'm still not quite sure what is going on. Do you?

Mac Mini/Lion Server/Airport Extreme Won't Sleep...?

I am at a loss with this one. I have a Mid-2011 Mac Mini running OS X 10.7.4 Server (11E53) connected via gigabit ethernet to an Airport Extreme. This computer will not sleep on its own using the system sleep timer.
If anyone has any ideas that may help, I'm all ears! The Mac Mini should sleep as intended and the Airport Extreme router should wake it if network resources are requested via a Magic Packet. This same Airport Extreme does wake the other computers on the network just fine when they are configured to Wake on Lan (womp 1 in the pmset -g output, below).
The server is configured to offer the following services: file sharing, Time Machine and screen sharing.
The power saver settings on the Mac Mini are configured to sleep in 45 minutes, turn the screen off in 1 minute and wake for network access is enabled. The output of pmset -g is below for reference:
Active Profiles:
AC Power                   -1*
Currently in use:
hibernatemode      0
disksleep          10
womp               1
networkoversleep   0
sleep              45
powerbutton        1
ttyskeepawake      1
hibernatefile      /var/vm/sleepimage
autorestart        1
panicrestart       15
displaysleep       1
If the Mac Mini is manually placed in sleep mode, via the Apple Menu or the button on the Login Screen for example, then it will sleep just fine. While the Mac Mini is sleeping, it will wake properly when the shared resources are accessed via another Mac on the network. For example, if the Macbook Pro tries to begin a Time Machine backup using the Time Machine Server on the Mac Mini, it will wake just fine and the backup will complete with no issues. The Mac Mini will not sleep again using the system sleep timer and must be manually put into sleep mode.
There is one printer (Canon MP560) installed on the Mac Mini, connected via USB, not shared on the network and no print jobs stuck in the print que.
I tried using the PleaseSleep software but that causes problems when the Mac Mini is used via Screen Sharing. When the Mac Mini is controlled remotely via Screen Sharing, PleaseSleep waits about a minute into the session and forces sleep mode, cutting the session short prematurely. This is unacceptable.
Also, there are no assertions that would prevent system idle sleep using the system sleep timer, as seen in the pmset -g assertions output below:

I Have the same issue with pleasesleep.
No ARD Session without sleep ;-)
My stup is a little bit different to yours.
My MacMini act as an HTPC for Plex and it dosent sleep as well.
I guess it has something to to with External USB HDDs or in your case printers or USB Hubs or etc. etc.
I found a AppleScript called Nacrolepsy 2.0
It dosent work probebly right now but I hope It could be a solution in the near future.
Take a look at

Mac mini "Overtemp" signal and sleep received regularly.

mac mini "Overtemp" signal received regularly.
been researching the regular "Overtemp signal" received by my mini (Mac Mini PPC G4/PowerMac 10,1, 1.42GHz, 1G RAM, Tiger 10.4.11) followed by forced sleep since around the time i updated adobe flash a month ago. it goes to sleep whenever i run streaming video or multiple resource-heavy apps. the fan motor seems to top out, wind down and the mini's power light pulsates slowly/softly. if upon waking the mini a video or heavy process is still running, the cpu often sleeps before i can quit any such process.
i tried reverting to an older version of flash to no avail. i have reset both the PMU and PRAM. i've run Disk Utility from the system disk. iStat Pro reports an average of 130°F/55°C. around a year ago i opened, cleaned and upgraded the RAM in my mini in a clean room. can't imagine it could be worse in there than then when the computer functioned fine.
i found out about Narcoleptic Aluminum Powerbook Syndrome, and found a user that had most carefully removed his PB's temperature sensor. is it possible that i have a faulty sensor? bad fan (even though it sounds like it runs clean)? anything else i could potentially fix using iFixit's manuals?
here are my log files:

Is it possible that the air vents have become blocked? One mini owner had a cat that liked to sleep next to the mini, which caused the air vents to get clogged with cat hair.
Do you have any print jobs that haven't completed? OS X can try to reprint, causing CPU to spike. Doesn't sound like the issue here, but worth a check.
Definitely sounds like a flash-related problem. Have you tried ClickToFlash? It can be downloaded here: http://clicktoflash.com/ . I use this on our G4-based systems, including a mini. This may help.

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.

Won't sleep when I close the lid - HELP!

A while ago, my iBook G4 1GHz was knocked off of a table. The display was smashed and the whole display assembly was destroyed. I bought a new (used) display assembly and installed it. Worked fine, but when I closed the lid, the iBook woudn't sleep. I checked the placement of the magnet in the top case and I reset the PMU. Still no sleep. So I contacted the company that sold me the display and got a different one. Still won't sleep when I close the lid. I checked all of the energy settings, reset the PMU and even tried to force sleep with a magnet from another broken iBook. Still no sleep when I close the lid. It will sleep when I choose sleep from the Apple menu (OS Tiger) and when it sits for a while with the lid open, but not when I close the lid. Any thoughts?

My original problem has not been solved. The iBook still won't go to sleep when I close the lid. I have checked out any possible software causes, and have ruled them out. I have checked to make sure no keys were being pressed when I closed the lid. I took a magnet from another iBook top case and ran it down the side of the display to try to force sleep. No effect. I don't have any Firewire or USB devices attached, to that's not it. Apple, this board, PBFixit.com, and my local Apple-affiliated repair center have no idea why I am having this problem. Two display assemblies have experienced this problem. The original display had been destroyed in a drop. Could some internal damage, like maybe to the logic board, result in such a problem? It's odd that I am the only person out there who has had this problem. Weird, to be sure.

TB display w/MBA 2011 clamshell won't sleep, still glows in dark room

Subject says it all.
The computer is the latest model 2011 MacBook Air with Thunderbolt.
The display is the latest model 27" Thunderbolt Display.
I use the MBA in clamshell mode.
When I use any of the following methods to put the display to sleep, it darkens, but doesn't shut off the back lighting and I still see the mouse no problem.
• Hot Corner to force sleep (set via System Preferences)
• Control + Shift + Eject
• Waiting 5 minutes of inactivity (set via System Preferences)
I don't think this is right.

Software update finally kicked in and said there was a "Thunderbolt Display Firmware Update". The update was FAST and now my problems are solved.
Thanks Apple bugfixing elves! :-

Powermac G4 spontaneous startup

Hi to all on the forums!
My G4 800 Quicksilver has developed a problem following shutdown, after about 15 minutes, the machine starts up spontaneously. This has happened a handful of times in the last months. Most recently, the spontantous startup led to the alarming flashing startup light and bad hardware tone. Reset button dumped me into open firmware. Mac starts OK, but will shut down spontaneously during sleep.
Internal battery was replaced recently, but did nothing to solve these problems.
Would appreciate any help available to troubleshoot this.
Cheers,
Alan

Yes, it does reset the motherboard and does a more effective job of it. The garbled boot tone is disturbing though. While I have heard of having a clipped boot tone or any of the other tones mentioned on the link provided above the garbled boot tone is the puzzler. I'm thinking that it could be a combination of one of the components mentioned in the article and corruption of Power On Self Test that is masking the correct tone.
When you reset the motherboard as I outlined and go to boot for the first time pay close attention to the tone. Hopefully it will be different and give you some indication of what other component is acting up.
If it is a user preference that is corrupted then create and login as another user.
If it is a system preference then it could be tougher to track down but the symptoms you outline with the flashing lights and garbled boot tone lead me to think that something deeper is the cause.
When my computer starts acting up I usually run Applejack. It is one of the best free utilities that I have seen.
http://applejack.sourceforge.net/#top
Pay close attention to installation instructions and have an Apple keyboard handy for booting into single user.
I forgot. Are you using an Apple monitor that can boot the computer? There are reports of these monitors causing strange startups and shutdowns.

Spontaneous forced sleep?
