Mac randomly enters low battery sleep mode

Sometimes when my laptop is closed for a while, it wakes up with the white tinted screen with the progress bar. I would like to know why this happens, and how I can fix it.
Here are some more details:
It has a non existant battery mode

Either your battery is failing or your battery gauge needs to be recalibrated. Start by recalibrating:
When it shuts off charge for just a minute or two, then restart (hold HOME and SLEEP until an Apple logo appears). Deliberately run the battery down until the phone shuts off at 1%. If it shuts off above 1% repeat the above until you get to 1%. Then charge for 4 hours with the wall charger without using the phone. This process will recalibrate the battery gauge.
To prevent this from happening again about once a month run the battery all the way down to 1%, then continue until the phone shuts off. Apple recommends this in their battery help article, but they don't say why you should do it. The have some hokum about "keeping the electrons moving." Honestly! The iPad battery tip gives the correct reason.
If this does not resolve the problem you most likely need a new battery. If you are near an Apple store take the phone in and they can test the battery for you.

Does a mac perform self diagnostics during sleep mode?

does a mac perform self diagnostics during sleep mode? I was told it does about 10 years ago.

Russa, from the KB article you linked notice that those maintenance scripts are no longer invoked by cron. They are invoked by launchd:
Additional Information
The tasks are scheduled for 03:15 to 05:30 in your computer's local time zone. This is described further in "Mac OS X: Unexplained Disk Activity Produced by 'find' Process." These tasks do not run if the computer is shut down or in sleep mode. If the tasks do not run, it is possible that certain log files (such as system.log) may become very large in Mac OS X v10.5 or earlier.
Therefore no user intervention is required, unless you are running Mac OS X "Leopard" or earlier.
It may seem overly pedantic to bring this up but this common misconception has a tendency to lead people into believing a Mac requires the user to perform maintenance over and beyond what OS X already accomplishes by default.
As others have written, a Mac takes care of its own housekeeping. It is best to simply let it work as designed.

MBA fails to wake (Platform Failure) after entering Low Power Sleep state

2011 MacBook Air 13” model number A1369
The issue: every time the battery drains empty and the device automatically shuts off, it will not properly power-on after being charged. The display backlight is active (and apple logo on the rear is illuminated) although the screen is blank. The machine doesn’t respond to any command or action. The machine will not respond to ping requests and does not appear to attempt to join the network according to the Airport logs. Closing the clamshell and re-openning does not appear to make any difference. The only action that yields any response is to hold the power button until it turns off and then turn it back on again. This has happened 100% of the time since the MacBook Air was purchased. This behavior does not happen with the 2009 MacBook pro also running OSX Lion.

Complete reinstall of OSX Lion
Any advice?

I have the exact same issue 100% reproducible BUT I also know how to exercise the bug without needing to run down the battery. Simply do sudo pmset -a destroyfvkeyonstandby 1 hibernatemode 25 then remove the power cord, close the clamshell, plug the power cord back in so it charges for a second, then open the clamshell. You will be in the same blank screen state as if you had let the battery run out.
hibernatemode 25 basically just tells the computer to go into hibernate mode instead of sleep mode wheenver you close the laptop.
destroyfvkeyonstandby tells the computer to power down the ram as soon as it enter hibernate mode.
This problem is way worse than any of you suspect. In all probability the system was intentionally broken in order to provide a backdoor into FV2. Let me explain:
It's impossible to achieve a secure FV2 system without using the following settings:
sudo pmset -a destroyfvkeyonstandby 1 hibernatemode 25
because otherwise what will happen is your FV key will be stored in RAM during both sleep and hibernate states. That means if a bad guy steals your laptop while it's in sleep or hibernate state he's then free to take an unlimited amount of time to attack it. He will be able to retrieve the key from ram as DEMONSTRATED LIVE a few months ago at a security confrence. The tools to preform the attack to retreive the key along with a detailed writeup are availble here:
http://www.frameloss.org/2011/09/18/firewire-attacks-against-mac-os-lion-filevau lt-2-encryption/
So at the risk of repeating myself... the conclusion is it's impossible to have a secure FV2 MBA system because of this bug. I suspect it's a conspiracy because it's too convenient of a bug..
apple has the fV2 system insecure by default (key stored in ram by default) and then apple happens to have a bug that prevents you from flushing that key then hibernating which would be the secure way to do it. Too much of a coincidence.

Macbook Pro 17" (Mid-2009) Randomly Getting Stuck in Sleep Mode when Unplugged

Hey guys, this is my first time posting so please excuse me if I do anything wrong. Here's the issue:
I have a Macbook Pro 17" (Mid-2009) that has had an issue with the whole computer shutting down at random, but only when unplugged from the MagSafe power adapter. Upon scouring all the forums and discussions I could, I haven't found anyone with the same exact circumstances as myself, hence this post. Let me explain.
Many say it's a battery issue. That can't be, because this has been happening for months, and after I finally got my laptop repaired a few days ago, it still occurs. I had sent it in for a logic board failure, but consented them to fix any other parts that weren't functioning properly. Upon the return of my machine, I found that they installed a fresh hard drive, new battery, new logic board, and a new speaker on the right side. This must mean that neither the logic board nor the battery are the issue.
What else can this point to? Again, it only occurs when the Mac is unplugged from a power source, and it doesn't totally shut down. It goes half way, essentially stuck in sleep mode. The white indicator light on the front freezes, and the power button has to be held to fully turn the laptop off, then pressed again to reboot. It can last anywhere from a single minute to a few hours before shutting off again, and it's always the exact same circumstance, no matter what kind of computing I'm doing at the time.
Note that while no one else has found the solution to lie within resetting the PRAM or SMC (in the discussions I read), I still need to try that tonight and see if it affects anything.
Thanks in advance,
Sean

Macs are having problems with SSD drives. The root cause is the OS X journaling file system. The Apple-written SATA controller driver can saturate the bus at times, inhibiting performance. Some manufactures are even selling special "Mac" versions of their SSD drives that are slowed down on purpose to compensate for this problem. Unfortunately, the problem still exists in Snow Leopard, from what I've read.
Also, I read that Apple has secretly slowed the recent new laptops down (3.0GB/s to 1.5GB/s) to compensate for the problem.

Power mac G5 unexpectedly goes in sleep mode or shut down.

I have a very strange problem.
I was using my 2 year old G5 without any problem untill some weeks ago. Randomly it would go into sleep mode without any mesage, you could start it again by pressing any key. It would start working for a little while(minutes), but then it would freeze and either go in sleep mode again or eventually it would shut down (without any mesage). However the little light above the power button would stay on. If you don't touch the keyboard or computer it will try to start again by itself.
If in sleep mode it will just come back with the screens I was in or it will boot and try to go to login. I say try because sometime it will shutdown again before that.
It is not predictable when it will happen. Sometimes it doesn't happen for days and then suddenly two days in a row.
I thought it could have something to do with the power supply so I bought a ups power system, didn't help.
Who can help me with this?
Power Mac G5, 1.6 Ghz Mac OS X (10.4.8)

Thanks for the input
I did the PMU reset, but it didn't solve the problem. Two days later my computer had a nother episode.
I checked the console.log after that and didn't find any temperature messages.
I did find this:

What is causing my Mac to crash during the sleep mode?

Hello!
I would to have your help on this situation that i am having for a month or so... Ok... it started about a month ago, I turned it on and all of the sudden, it shut down, then rebooted on its own... (actually it rebooted like 3 or 4 times before running the system) I thought that it was odd. I had my Tech to look over and see what was causing to crash and all... he could not find anything then we all decided to leave it running all time... so we did. a week or two later, it just crashed when i woke the sleep mode and it went on the usual route as crashed and rebooted two or three times before going back to normal.
sound familiar to you guys? after that happened, we turned off the sleep mode and so far, it is doing good... decided not to update the system's Security software because it may have something to cause the mac to crash down...
the mac is 2 x 3 GHz Quad-Core Intel Xeon, 8 Gb 667 MHZ DDR2 FB-DIMM, running on 10.6.8
appreciate your help on this.

One more thing.... it makes weird sounds as well... very high pitch sounds that you hear in movies where UFO flying by while it is doing the rebooting...

My mac shuts down in prolonged sleep mode "because of a Problem".

If my mac book pro mid 2012 goes to sleep for a prolonged period of time I have to reboot it as hard start and get a message indicating that it shut down because of an problem. How Do I fix this?
I had my mother board tested at a mac shop in Nepal while I was there and it came back as everything being perfect.
It does not always do this though and for short sleeps it never does.
I have had extensive changes done to this mac such as a 16GB Ram upgrade and replacing the hard drive with a 1 T Crucial Hard Drive and removing the DVD Player and adding in a 256 Solid State Drive. So far everything has been working great. Just recently I notice this occuring with the sleep mode so as a result I just shut down the computer fully when I am not near to it or using it. Any advice as to what to look at or try out.

godlovestodance,
your Mid 2012 needs 1600 MHz memory modules. Is your currently installed RAM of this variety?
In your current setup, is it your 1 TB HDD or your 256 GB SSD that is in the optical drive bay?
One thing you can try is this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it still crash because of an extended sleep?

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.

Is it possible to shut down the MAC automatically while being in sleeping mode?

Dear all,
on my MacPro I use a setting that after 30 minutes of inactivity, the machine moves into sleeping mode. That works well.
Additionally I'm using a setup within the energy saving section, that the Mac should shut down every day at 10:00 pm and start or wake up every day at 07:00 am.
But it seems, that, if the Mac is in sleeping mode at 10:00 pm, he cannot shut down.
Does anyone has the same experience and/or knows any help?
Thanks in advance - helee29

Dear Martin,
Thanks for reply.
I checked the logs as mentioned, but honesly saying I'm not experienced enough to understand all this notices.
What I found out in the meantime by testing (try and error) is:
- if the Mac is in working mode (just the screensaver is working) the automatic shut down and restart to set times works perfectly.
- if the Mac is in sleeping mode, it doesn't shut down automatically at the set time, but makes an automatic restart at the set time
Ergo there is a problem to shut down the Mac automatically while in sleeping mode, but I still don't know what it is.

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.

Mac will not stay in sleep mode

My IMac running system 10.5.8 will not remain in sleep mode. I have tried closing all running applications and this makes no difference. After restarting the computer it seemed to function correctly for a short time then once again would not remain in sleep mode. The energy saver has no wake options set.

Here are 3 shots...of course things keep moving but I think I got most off.

when i check in device manager for power option in Realtek High Definition Audio property i also cant find that
plz suggest me a reliable solution for the same
thanks

Hi,
As Milos said, first thing we would do is see if all my hardware drivers are up to date. The Windows drivers are the best match for most hardware but you may have better results with drivers obtained directly from manufacturers.
Meanwhile, please try installing the latest version driver for Realtek High Definition Audio to test it.

Mac OS X 10.3 - sleep mode

Hi,
I have a G4 with Mac OS X 10.3.
Whenever I power back on the computer back from sleep, I no longer have access to the internet.
I have a cable connection btw.
I have to restart the computer so that it works.
Any known issues?

Hi post_scriptum,
Do you have in your System Preferences>Energy Saver>Options tab>"Wake for Ethernet network administrator access" ticked? Not sure if that is something that needs to be checked for the computer to connect when waking from sleep or not but worth looking at.
post back if still no luck,
