MBP randomly goes to sleep, even while I'm using it.

So, for about a week now, I've found that my MBP will go to sleep (as in the screen suddenly turns black). And when I press a key or click, the computer makes the sound that it does when it's coming out of sleep.
Now this isn't really a big issue at the moment, however I have no idea what's causing it and am afraid it could be a potentially bigger issue.
Anyone have any idea what it might be? Should I get it checked?

OK, that is one possible problem apparently out of the way. If it happens again (or if you can remember the times/dates of previous events) have a look in a utility called Console which keeps the logs. This actually seems to have changed with the 10.5.7 update and now has an "All Messages" section: useful if you have this. If not, the Console Messages, or one of the other logs might give information that could help in analysis.
As I suggested in the earlier posting, if there is nothing, that would point to a power management problem and a hardware repair. Console might help track it down if it is software-related.

My iPad randomly goes into sleep mode while I am using it?

All of a sudden, when ever I use my iPad 2 it goes into sleep mode. It did it three times while I typed this message. As I am running an app it will just go into sleep mode with out me doing so and I have to press the home button to wake it up. Doesn't matter what app I am running. I have 4gb of storage available. Most of the time it brings me back to the app I was using when it went to sleep. Has anyone else suffered this issue. I am running the latest iOS 6.0.

What "issue"? This is perfectly normal. By default, all (fairly-recent) Apple products will go to sleep if left idle for a certain period of time. This is NOT normal, however, if in the app, you are pressing buttons on the screen. If you are doing something like reading, for example, try setting your iPad to not go to sleep that quickly.
(Google how, I don't completely remember.)

After Mountain Lion, iMac goes to sleep even while Quicktime is converting files

Hello!
After Mountian Lion, I have had to change my Energy setting to NEVER put the computer to sleep. iMac has been going to sleep even while it is converting files. This never happened with the previous OSX.
Does anyone know why it goes to sleep even when tasks are being performed? It's very annoying.
Thanks!

Same problem here on a Mid 2007 Core 2 Duo -- set to "never" but keeps dozing off.
Extra lousy since it's also the print and media server.

Windows 7 RC goes to sleep automatically while in use

Hello everyone!
When running Windows 7 RC on my laptop it sometimes goes to sleep even when I am using it. For example, while playing a game the screen just goes black and Windows sleeps. That is very frustrating because I have to wake it up and see that the game I was playing is closed. This problem occurred many times and during several different games. Although not every game is affected by this. I am not sure it happens too when I run applications.
I pretty much turned sleep off in all the settings in the Windows Control Panel. It is only suppose to sleep when the battery has only 1% left but my battery is always charged when running Windows.
Maybe I should also mention that my battery is in a very poor condition. I use this battery since about little more than a year and it has run through 385 cycles with only 27% of health left.
I hope someone can help me with this because if I cannot even play games on Windows then there is no reason to keep my Boot Camp partition.
Thank you!

I have the same problem you both have, and I have not confirmed this with Apple, but I'm almost positive it's an over heating issue. When your MacBook Pro goes to sleep while you were gaming, hurry up and touch the left fan vent next to the built in keyboard. Are we cooking eggs here or what? I'm presuming as a failsafe, once the CPU/GPU hits a certain temperature, an auto sleep function is triggered to prevent the system from cooking itself. As a work around I bought a laptop fan, which keeps it a lot cooler and has dimmed down the automatic sleeping issue. I think the main issue is that Apple's Bootcamp drivers aren't supporting fan control, therefore the fans are staying at their normal speed, when they really should be maxing out their speed when you're gaming.
Hope this helps.

Imac Randomly goes into sleep mode...Hard to start

My IMAC G5 will randomly go into sleep mode while I am in the middle of using it. Typically the fan noise increases and than it auto goes into a sleep mode. It also has issues starting. I have to press and hold the power button for it to kick on while also hitting keys on the keyboard to trigger it. Help!?

Here is the system log it looks like its over heating?

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.

My laptop randomly goes into sleep mode

I'll randomly be on a site or listening to music and then all of a sudden it goes into sleep mode. I'm very aware that it goes to sleep while you've been away from your computer, but it'll go into sleep mode while I'm using the computer. I changed the power setting so that it takes longer to get into sleep mode thinking that would help, but it doesn't. I ignored it at first but it happens more often now and its getting annoying. Sometimes I'll move the mouse pad to wake it back up and it sounds like its going to come back, bit it just goes to sleep again. Its really annoying and frustrating and I don't know what's wrong with it. Anyone have any idea what's wrong with it and how to fix it? My warranty expired this passed March and I can't afford to get it fixed.

My PB G4 keeps randomly going to sleep!!

First of all, my apologies if this topic has already been discussed...due to the issue I'm having, I have no idea when my computer will decide to go to sleep!
I've had my PowerBook G4 since 2005. For the past few days, it randomly goes to sleep. I can be in the middle of doing anything (like typing this) and it will go to sleep (it just did twice while typing the above sentence). When the battery is in, it does is every few minutes. When just hooked up to power (no battery), it does it every 20-30 minutes, but, in both instances, will rarely do it once or twice in a few minutes. When the battery is in and it goes to sleep, the battery does not feel too hot, so I don't think it is overheating.
When it goes to sleep, I can just hit a few random keys and it will wake up. Once or twice, I have had to unplug it and remove the battery to restart it.
Other (possibly) pertinent information:
-I always have it plugged in while using it-very, very, rarely use it with just the battery. No specific reason, just habit, I guess.
-I have never replaced the battery or the charger.
I will admit that I haven't always kept up to date on updates, and I am sort of technologically clueless. Because of my lack of knowledge, this freaks me out a bit that my computer is doing this. I love it and have never had any problems before! I know I can take it to Apple, but, I don't want to take it if it is an issue easily resolved. There is only one Apple store in my area and you typically have to wait a few days for an appointment.
Any advice would be greatly appreciated.
Thank you!!

Welcome!
I'm suspecting you 5-year old battery might have something to do with it. The clue to this is:
Once or twice, I have had to unplug it and remove the battery to restart it.
That sounds like you're short on power. Mine did that when the battery was dying, although not while the A/C adaptor was connected. Still, a very heavy-duty program can draw power from both the battery and the A/C adaptor in newer Mac notebooks, so that's a possibility in older ones.
To check your battery's condition, do "About this Mac..." from the Apple menu and click "More Info..." in the resulting window. You're now looking at the very informative utility, System Profiler. In the left-hand pane, find and select "Power." Then look at the info in the main pane for "Battery Information." You don't say what version of the Mac OS you have, and Profiler can show slightly different info from Panther to Tiger to Leopard.
Anyway, you need to look for the section under Battery Information that has items like "Charge remaining (mah)," "Full charge capacity (mah)," and "Cycles" or "Cycle count." The last two are the most important in determining the condition of your battery. Copy and paste that section into a reply to your own thread and we will have a good start on figuring out what to do.
Please add your version of OSX to your equipment line where it now says PowerBook G4. It's also useful to show the processor speed. I assume you don't need to post the screen size as you've posted in the forum for PowerBooks with 17" displays.
Had I only my trusty old PowerBook in my equipment line, it would read:
PowerBook G4 17"; 1Ghz processor; OS 10.4.11; 1G RAM
That doesn't make a difference for the question you posted today but is helpful to others should you wish to post another question. Saves a responder having to burn a post asking for the basics. BTW, all that info is available from "About this Mac..." or from the opening pave of System Profiler.
I'm glad you found us--I'm sure you will get some useful help here.

Computer randomly goes to sleep and not waking up

My computer randomly goes to sleep-while I'm using it, and it won't wake up. Any suggestions? Is it something I'm doing?

Check temperatures by using Temperature Monitor -application. Atleast Macbook did this when there was problem with temps, cleaning heat sink and reapplying thermal solved the problem. G5 -based iMacs are known for running very hot temperatures and there was all kinds of motherboard failures as well as power supplies going bad.

Macbook Pro keeps randomly going to sleep.

My OS Lion Macbook Pro keeps randomly going to sleep.
There doesn't seem to be any pattern. It looks like I may have to get it repaired?

No I didn't do anything like that, but...
I've found a pattern/cause!
It's every time I open the app store. Why on earth would that be?

Log in screen appear after Mac goes to sleep even if screen lock is turned off.

Log in screen appear after Mac goes to sleep even if screen lock is turned off. This happens usually but not always. Using Yosemite, 2 year old iMac. This has only started to occur recently and it happened in Mavericks also.

Howdy stkh,
You may want to check the General pane of the Security & Privacy System preferences to make sure that the Require password...after sleep or screen saver begins is not checked. See this article for reference -
OS X Yosemite: General pane of Security & Privacy preferences
Thanks for using Apple Support Communities.
Best,

Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight etc. It was fine before the upgrade and I have all the system preference set to "never turn off"

Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight (cd's / recording etc. It was fine before the upgrade and I have all the system preference set to "never turn off" - Help !!!

Good advice from Linc Davis that should sort out your query i think...
However you dont want to set your MBP to never go to sleep...
Adjust reasonable sleep settings...
And the download an APP called caffiene...
When you click it you can have your MBP never go to sleep with a single click of your menu bar... and with another click it can go to sleep normally to maintain the laptop...
Simply click the cup... To toggle never sleep/sleep

My brand-new iPod touch (5th Gen) battery takes a very long time to fully charge, even while not in use. Why is this and what should I do?

Just recently bought a brand-new iPod touch, 5th generation. To be exact, got it two days ago, this past Saturday, on 12/13/2014. Initially, when I first turned it on, it had a fully charge and I didn't need to charge it. I also didn't see anything in the very small and limited start-up guide you receive with it to charge it for a certain amount of time before use, or to use it until the battery dies, then charge all the way, like a lot of electronic devices have you do when you first purchase them.
So I was assuming I didn't need to do anything like that. First question, should I have charged it for a period of time before use? Should I have used it until the battery died, then plugged it in and charged it fully before use? Or is none of this necessary initially and iPod batteries are good to go from the start?
Please excuse me if this is an obvious question, as this is my first ever iPod. Anyways,like I said, nothing in the "instructions" said anything about that, so I didn't do it, I just used it until it got below 20% battery left, then I plugged it in.
Now for the battery itself, it takes literally a day or so to fully charge, even while not in use. Even if I use it for a while, turn off the iPod to make sure it shuts off all background data and apps, and then plug it in to charge, it still charges extremely slowly. I've never seen a device take this long to charge. As for the battery life itself, I'd say at full charge it lasts about 4-5 hrs, maybe 6, and then I have to charge it again. Meanwhile it takes around 24 hours, without me using it, to fully charge. If I use it while its charging, the battery decreases faster than it charges, and eventually I'll get the typical "20% battery remaining" message pop up.
I know it is charging, as the lightning symbol is next to the battery symbol. Specifically, right now, I plugged it in about 1 hr 30 minutes ago, and it has barely gone up. Also, whenever I press the home button to check the battery, I can see it jump down from about 50% to somewhere around 25%-30%. What is that about?
This is really frustrating, and I'm seriously contemplating either taking it back and trying my luck with a different iPod, or just taking it back and getting my money back. Any help and clarification on this matter would be greatly appreciated, and I'll answer any questions I can to shed more light on this.

It will take longer to charge the 5G's battery than either the 3G or 4G's battery.
Not Charge

- Try another cable. The cable for 5G iPod (lightning connector) seems to be more prone to failure than the older cable.

- Try another charging source like a computer's USB port
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store.

IMac randomly goes to sleep / Previous Sleep Cause: -100

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. Are those causing issue? If so what can I do?
/private/var/log/kernel.log says
   "Previous Sleep Cause: -100"
Any idea what this is?
Thanks!

I took the iMac to nearest AppleStore and they opened it and cleaned up inside.
After that, it has not yet gone to random sleep yet while I've been trying to reproduce heavy CPU/GPU load for ~1h (while I could make it happen in 15min this morning).
So far highest temp went down to:
CPU 55C             => 44C
power supply 95C => 72C
northbridge 89C     => 82C
graphic processer 86C => 70C
Tech at AppleStore bar didn't know what Sleep Cause: -100 is.

Computer keeps going to sleep even though it is set up not to

I recently helped a friend set up his iMac to stream to his home stereo system so things like Pandora could be played throughout the house. The problem we are having is his computer keeps going to sleep and back to the log-in screen. In energy saver, we set the computer and display to never go to sleep. We also un-checked the box that says "put the hard disks to sleep when possible." Even after doing this, the display still goes dark and when the mouse is moved to turn the screen on it is back at the log in screen. This causes pandora to stop playback, which is not good since this is why we set up the streaming in the first place. Why is the computer still going to sleep when we are telling it to never do so?

HI Ty,
Couldn't hurt to check the hard disk.
Follow these instructions to verify the hard disk for errors:
Open Disk Utility, in the Utilities folder in the Applications folder.
Select your disk, and click First Aid.
Click Verify Disk.
If the disk needs repairs, do one of the following:
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the menu bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click Repair Disk. When Disk Utility is finished, from the Menu Bar select Utilities/Startup Disk. Select MacintoshHD 10.5 in the window and click: Restart
If you don’t have a Mac OS X Install disc, restart your computer while holding down the Shift key. As your computer starts up, it performs a disk check similar to the one Disk Utility performs.
