Mac didn't go into sleep mode... Now all sorts of messed up

Gives me a message: says it shut down because of an error. Error report says "panic" as cause. Reset date to Dec 31, 2000, and gave errors about sever safety/validity when opening mail. Wouldn't correct the date/time and had to do it manually. Battery read 0% upon startup. Battery was 100% when I left this morning and closed it.

Hello josfromkerkade. Please contact me so that I can get more details.
We'd like to understand which monitor you're using, how old it is, which Thunderbolt port you're using (tethered cable or TB port), & the version of firmware.

Mac Pro randomly goes into sleep mode

My (mid 2010) Mac Pro, OS X.6.8, randomly goes into sleep mode and I can't wake it, have to power it off and reboot. Just started to the best of my knowledge Friday (Jan 6, 2012) I've had it happen surfing the web in Safari, while working on an illustration in Adobe Illustrator, while running Apple Hardware Test, using 23" LCD connected by HDMI and DVI-D, Disconnected monitor and connected 12" Cintiq (LCD Tablet).
The monitor goes black, says "there's no signal coming from your computer", none of the keys will wake it. I have to hold down the power button until it turns off then power it back up. The time between the sleeps varies, 38min, 1hr 34min, 5min, 2hr 17min, 12min, etc. I disconnected everything (except keyboard, mouse, monitor) still the same. Opened and removed the ATI Radeon HD 5870, and noticed the PRAM battery, replaced it with a new one, thought that fixed it, worked for a long time then it happened again.
Tried Apple Hardware Tester again, it said everything is fine, ran it again an error popped up: 4SNS/1/40000000:Te1S-99.364, wrote it down then it slept.

The next time this happens open your mac and see if there is still a fan running. If so you are not sleeping, you are in a thermal cutoff. Keep you mac cover off.
Now reboot as you always do. Take a look at the fan in your 5870. Is it spinning? If so, try to keep an eye on it and see if you can "catch" it not spinning.
When the fan doesn't start, or if it does then stops, the card will overheat and the machine will go into thermal cutoff. The amount of time is variable.
I speak from experience. I am currently on my third 5870 video card. Both the previous two had this fan problem. The only wrinkle in my theory for you is that I wouldn't expect more that, say, 15 minutes of up time at the most, not hours like you got. But it may be that your card is starting ok, but stops sometime later. I chalk it up to the lousy fans Nvidia uses in the 5x70 cards.
FWIW, if you happen to catch the fan stopped before the machine goes into thermal cutoff you can give it a little nudge with your finger to get it going again.
I recommend one of the various temperature monitors. I use iStat Menus and display some key temps in my menu bar. Of course after going through two of these cards I am a bit paranoid!
Some other temperature monitors:
iStat Pro
Temperature Monitor
Hardware Monitor
Note, after typing all this I also realized you got a AHT 4SNS error. I would run AHT again to see if you get that error again. If so that means "Check Main Logic Board" and you may have a more serious hardware problem than just a video card! So my other recommendation is that when you machine fails again look inside for any lit diagnostic leds. There's some near the dimms but there are others on the board as well.

HT1338 Mac pro wont go into sleep mode

My mac pro has to physically be restarted everytime it should go to sleep. I run it through a flat screen TV and when I go to sit down and use my computer the screen is black and the indicater light on the front of my computer is solid, not flashing. Also I had my computer set up to turn off around 1 am and automatically turn on before I woke up in the morning, I have since turned this schedule times off but my computer is still following the schedule. I updated to today, but all this started after the most recent update. The only way for my computer togo into sleep mode is to physically push the button on the front of the MAc Pro tower.

System Preferences/Energy Saver - set Computer sleep to never. At times the OS fails to detect activity and allows sleep even though there is something going on.

My Mac doesn't go into sleep mode

My computer will not go to sleep even after i reset and reset everything in site. I ran the disk first aid and no problems were found. but my mac simply won't go on sleep mode.
can anyone help me?

Hi Mac,
Thanks for your response.
As I am computer illiterate, meaning I don't know what peripheral is, I have no idea how to go about fixing this problem. I also don't know which would be firewire devices.
However, I disselected the login items, but that still didn't work.
In the Console I received the follwoing errors and warnings:

Prevent my MacBook Pro to turn into sleeping mode

How can I prevent my MacBook Pro to turn into sleeping mode when playing music on it with Itunes?

System Preferences -> Energy
Put slider to "Never". But this will prevent your Mac to never turn into sleeping mode, not just when playing music.

HP 2309v Monitor goes into sleep mode

My monitor an computer have been working fine for three months (since i bought a new computer Packard Bell) all of a sudden my monitor stopped working correctly. It now says VGA : no signal and gives recommended settings - then goes into sleep mode. All cables are plugged in correctly, i have restarted the computer countless times (even taken it apart and removed the RAM as suggested on another post). To no avail. Please help.

Hello SEAN1982,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that you are having issues with your computer display not working. Given your statement that you have tried plugging it into two TV's I am assuming it does not work on them either. This would indicate the problem resides on the computer itself. I am recommending that you review and follow the HP Support document: Windows 8 Safe Mode, which should enable you to boot. If you are able to boot into Safe Mode and see the computer again follow the steps set out in the HP Support document: Using Microsoft System Restore (Windows 8), which will walk you through restoring your computer back to before this became an issue.
***NOTE: Do not worry about the documents being Windows 8 and not Windows 8.1 the steps are the same.
If you cannot boot into Safe Mode the issue appears to be a physical issue and I think it would be best if you contact HP Technical Support for repair options.
I would like to thank you for posting on the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!

IPad doesn't go into sleep mode when guided access is enabled

My iPad doesn't go into sleep mode when guided access is enabled despite having set "enable sleep mode" to on in the settings menu. COnsequently, my battery life drains very quickly during the day as the screen doesn't dim or go into sleep mode at all. Help!

Seems this feature is lost with iOS 7.0.4. I just bought 4 iPod Touches for employee use and NEED to have sleep mode enabled for guided access to conserve battery life.
I did have 1 iPod that allowed me to enable sleep mode (and I tested that it allowed the top button to be pressed to immediately go to sleep), then after it ran the 7.0.4 upgrade it no longer allowed sleep mode when in guided access (I did not check the original version of iOS on the iPod but it was obviously older than 7.0.4).
Is there some new hidden way to turn this on or did Apple delete the option?

I have a WD Passport HD attached to my Mac. When it was last connected it went into sleep mode and ran out of battery. Now I cannot find my HD in Finder and Disk Utilities is telling me it cannot repair the HD. Any ideas on how to recover my data?

I have a WD Passport HD attached to my Mac. When it was last connected it went into sleep mode and ran out of battery. Now I cannot find my HD in Finder and Disk Utilities is telling me it cannot repair the HD. I can see the HD but the volume part is greyed out. Any ideas on how to recover my data?

There are other methodologies of scanning a HD
which involve data extraction, but loss of metadata is often the result if the directory is corrupt.
Metadata is the info on what the data IS.
Like having all your papers thrown in the air, its all there, but just a giant mess.
This is why you always always must have several external HD redundancies of your data. One isnt enough, neither is two really.

Mac Tower Pro 10.8.5 keeps going into sleep mode

Purchased from Apple, refurbished 2012 Mac Tower Pro. At the same time, purchased a new Dell U2713HM, 27" monitor.
Have been operating on this new system since about the first week of December 2013.
Issue:
The computer has constantly gone into sleep mode after a few minutes of no activity. I can have iTunes radio playing, but the system still goes into sleep mode. As I am typing and moving the curser, the machine stays awake.
This has caused much frustration because when it goes into auto sleep mode, it quits all programs that I am in, and when it does this, I lose all the work I had accomplished. It litterally closes everything and goes to sleep in about 2-3 minutes of no activity.
BTW: the computer and monitor have all its new OEM cables that came in the box, when I purchased the units.
Solutions attempted:
System Preferences — Energy Saver: computer sleep and display sleep set to "never" and unclicked the box "Put hard disks to sleep when possible."
Dell settings: Turned off all energy savers.
Results:
Nothing. Problem persists.

I apologize for the angst. The problem has cost too much money in lost time and material because when it would automatically shut down after a few minutes, all my work was lost.
I misunderstood the terms of the warranty. Thank you for your input and patience. Much appreciated. For the benefit of others that experience this with a new Mac that auto shuts down. Check the following:
1. Go to System Preferences.
2. Click on Security and Privacy.
3. Click on Advanced (bottom right corner)
4. If the first line is checked (Log out after 5 minutes of inactivity); uncheck it and then click OK button.
5. Be sure to click the lock before existing Security and Privacy.
Now the machine will cease shutting down programs to go into sleep mode as soon as machine is inactive for a few minutes.

Late 2012 Mac mini with OSX 10.8.2 has started shutting down instead of going into sleep mode.

Sometime in the last week or so my mac mini has started going into full shut down instead of sleep mode.
I have tried checking and unchecking energy saver boxes but haven't found anything which will get me back to where I used to be - and I haven't knowingly changed anything to make this happen.- maybe an OS update caused it?
The machine will fire up with a tablet click rather than needing the reset button to be pushed so clearly the machine is sort of halfway between sleep and full 'off'. Most frustrating as one of the key issues for me in getting this my first mac was its easy sleep and super quick fire up compared to windows.
Any help appreciated
Oh yes I just remembered that I did just install 2 8gb of crucial RAM (to replace the supplied 2 2gb but surely that can't have anything to do with it - can it)?

Adding to my first post I can now advise that when the mac goes into sleep mode the light on the front stays on (it does not pulse so clearly it is not really sleeping).
When i click the tablet / keyboard this is actually what triggers the mac to reboot
I have tried resetting the SMC as per the following link to no avail

HT204074 Watching a TV series, purchasing them one Ep at a time. Anyway after watching Ep3 I purchased Ep 4 but got a call so my laptop i went into sleep mode. Just came back n now it says that 90 days

'You can download past purchases on this computer with just one Apple ID every 90 days. You cannot associate this computer with a different Apple ID for 67 days.'
What is this? It's the most frustrating thing, and I just wnt to scream 'I DIDN'T'. 23 days ago I did because I was unaware of the new 90 day rule.
But this time, i didn't do anything. I was watching a TV series, and I was purchasing the episodes one at a time (in hopes that this would encourage me to stop and go to sleep after i finished the next one). Anyway I had just finished watching episode 3 and purchased 4 and it had begun to download, when I left my laptop to go get something to eat came back n it had obviously gone into sleep mode. so had to continue the download BUT when I try to continue the download the 'message' pops up. I haven't signed out, it's purchased under j_akale, so I don't understand.

Frist tip, after installing software updates (I assure your machine started off with 10.4.2 and when you first used it, you were promted to update to 10.4.4.), go into the utlities folder (under applications) open disk utlitity and verifity and repaire disk permissions, this will greatly boost preformace and may fix your problem. (In fact do this once a week) Go ahead and run the Techtool (Applecare hardware test CD) and check for any problems. If these come up with nothing, I'd call Applecare and tell them what is happening. Applecare will cover you at any Apple dealer and some Apple resellers as well. Going elsewhere will kill your warrenty BTW.

I got a Macbook Air. My system language is russian but the login password is english. I pu the laptop into sleep mode, then wanted to log in again, but the language seems to have switched to russian, there's no language change button! How do I log in now?

Severia,
I tried your solution, but it did not work with my laptop. After I restart the laptop, the language does not change and I cannot type the password in English language. Do you have any other suggestion?
Thank you.

When I use I tunes radio,click pause,leave mac to go into sleep mode,wake mac

when I use I tunes radio,click pause,leave mac to go into sleep mode,return press play I tunes will not resatrt on same station. I have to pick another for a few seconds and then return to original. then it works ok.
not a big problem but its annoying. Any ideas ?
thanks very much

I lugged the G4 around town to three different computer repair shops, and they all confirmed that I had installed the fans correctly, and all fans were running fine. Of course, this only makes the problem harder to solve.
Furthermore, my friend was using the G4 last night when it was a cool 72 degrees (F) in his apartment, and the computer still forced itself into Sleep mode after just over an hour of use. He was using Final Cut Pro at the time, editing a project spread across two external FireWire hard drives. I just can't imagine this amount of activity overheating the G4, which was my editing workhorse for six years before handing it over to my friend.
When I replaced the cooling fans, I did select new fans with slightly lower airflow than the original fans (which many people have replaced, due to the amount of noise they produce). Any opinions on whether that could be the issue?
_Case fan:_
Original: 151.85 CFM airflow
Replacement: 109.6 CFM airflow
_Power Supply fans:_
Original: 38.1 CFM airflow
Replacement: 26.5 CFM airflow

External usb disc used for Time Machine backup disconnects when Mac has been into sleep mode

I use a 1Tb External usb disc used for Time Machine backup which works fine, but when the Mac goes into sleep mode & powers back on I get a message stating that you should always eject the Drive before removing.
Any suggestions on how to get around this problem would be welcome

Look at the root of your hard drive for a folder called Backups.backupdb.
Or, a sparse bundle disk image for one of mobile computers that might have tried to back up to your Mac.
If you have those, remove them and try again.
