Random shutdown and charging issues

I have only had my Note 3 for a few days and since I activated it there has seem to been some issues. First it doesn't seem to charge completely and drains the battery very quickly (it was my understanding battery life was supposed to be better than the Note 2). It also randomly shuts down for no apparent reason. I also have been having a lot of trouble with apps closing saying unfortunately it has stopped working. Beginning to think that I might of gotten a faulty phone, or does anyone have any suggestions?

My Note III just started with this problem 4-5 days ago. The first time that it had powered off I thought it was just a fluke, I powered it back on, it had something like 30% battery left. Thinking it may have been because of the battery level I charged it back up to 90% and this seemed to resolve the issue for the time being. The next day it started randomly powering off I noticed right after it would go into sleep mode. Fast forward to today and the issue has gotten progressively worse, not only does it power off but the touch screen stops responding at random times, the battery is draining at an accelerated pace and the phone seems to run hotter. If I remove the battery and let it sit for 5-10 minutes it returns to normal operation but that only lasts about 30-60 minutes. The only thing I can think of that may have caused this is an app update that rolled through 4-5 days ago, I have never dropped the phone, never gotten liquid on it, I am super careful with this thing since it costs an arm and leg. I have just done a reset under backup and reset > personal data > reset settings, all this does is reset system settings back to default, it leaves all you data intact, I'm not hopeful that this will work. If it doesn't, I'll be doing a factory reset (complete wipe) as a last resort before I take it into Verizon.

Random Shutdowns and Logs

Like some others, I have started having random shutdowns and some high fan activity. So I can probably guess that it is the power supply.
However, in previous posts on this topic, some have suggested checking a couple of different acitivity logs that exist somewhere on everyone's Mac.
My question is...what logs might they be, and how does one find them?
Thanks for any assistance....
CHUCK
iMac G5 Mac OS X (10.4.8)

Hi Chuck--
But is there a log that would show me why the
computer randomly shutdown?
Shutdowns and going to sleep are two different things. If your power supply is starting to fail, your computer will periodically just shutdown completely. Sometimes, the fans will run faster, but often, they won't. If this happens, you can find it out by looking at the system log right after you reboot, or by typing a command in the Terminal application. Terminal is found in your Utilities folder. You would just open it and type the following command, followed by the "enter" key:
<pre class="command">sudo dmesg | grep shutdown</pre>Unfortunately, those codes are not published anywhere. However, my iMac G5 has shut off a couple of times due to the UPS inexplicably draining its battery. The last time was Sunday night, and here's the code I get from that command (you'll have to type in your password when it asks):
<pre class="command">AppleSMU -- shutdown cause = -110</pre>I've also seen -118 and -122 as the error codes. I think the latter came when I had the same random shutdown problem. You can also find the same information in your system log, using the Console application. However, it's mixed in with a whole bunch of other stuff, so it's harder to find. You can use the little search window at the top right of the Console app to help you narrow it down. If your system has been on overnight since it last shut down, you may need to look at an older log, so look at the one marked system.log.0.gz for yesterday, and so on, where the larger the number in the name, the older it is.
The second problem is that the computer overheats and puts itself to sleep. This is, fortunately, easier to find in the logs. Once it cools down a bit and you can get it running again, use the Console application and see if you see lines much like this:
<pre class="command">May 28 10:49:08 localhost kernel: Thermal Manager: max temperature exceeded for 30 seconds, forcing system sleep

If you see this error, the fans can't get enough cool air flowing through the interior of the computer. Some people have reported that they've had success in fixing it by carefully cleaning out the vent holes at the bottom of the iMac, so air flows freely again. They've reported that pet hair or dust can get in there and clog it up.
On the other hand, this log is from a replacement logic board on that iMac. When I showed the techs that log, they didn't even bother with any tests, other than look to see if the interior of the computer was dirty (it wasn't) before they decided to replace the logic board as a defective.

Satellite A300D-15B - Switched off and charging issue

Hi
I have a Satellite A300D-15B, running Windows 7 32bit, which bought quite recently used. I have encountered a couple of problems which I hope someone can help me with!
Firstly, the day I got the machine, it switched suddenly, but turned back on immediately and seemed to be ok. Afterwards, 3 weeks later (saturday 2nd July) I was installing some software when I got a virus warning from AGV, within a few moments the machine again turned off suddenly. Unfortuanetly this time it would not turn back on and the charge/AC supply lights would not come on. After doing some research I found that disconnecting the BIOS battery and dissipating the power enabled me to turn the machine on. Is there any known issues which could be causing this?
Secondly, once I had got the laptop to turn on after the sudden shutdown on staurday, I have found the charger still wont register as being plugged in unless i use the folling procedure.
1) diconnect the mains fuse cable from the transformer block
2) remove the battery
3) plug in the DC jack
4) reconnect the mains cable to the transformer which causes the mains light on the laptop to turn on.
5) reconnect the battery
The laptop then charges normally, I am using it to write this post.
I have to use this process everytime the machine is unplugged from the the mains or charger, which is irritating and also a worry that there could be big problems on the horizon.
Any help would be hugely appreciated.
cheers
John

Hi
I upgraded it to 7, the first time it shut down was the first time it was switched on after the recovery disc had been used. Could that be an out of date driver on original settings? Then upgrading to 7 giving similar problems?
I upgraded to 7 not a fresh install, which I never usually do.
The charger is a genuine unit not a 3rd party, I won't use them as I've had issues in the past. I'm just concerned it's a mainboard problem given the shutdown and subsequent strange charging behaviour. Do these have EEPROM's in the chargers and maybe clearing the CMOS has caused a recognition problem?
Cheers

Touch Screen and Charge Issue

Hey everyone, first time here but also registered at precentral
Asked there, but I'm hoping here would be a better place to voice this issue.
This is my 2nd New Pre I had as the first one had random keyboard loss when my phone died due to battery. I was able to fix it with a 5th batt pull, but I wasn't chancing it..so swiped it.
Well, got my phone with 1.2.x out of the box and tested fine at the store. When home and updated to 1.3.1. weeks later the issue.
touch would random stop working...I had preware so I decided maybe it was a patch or app messing it up (I noticed I didn't have message foward working after update)
So I Doctored it. The Process went nervously fine, up until I got to the home screen. The Touch went out again!
But after messing around a bit after getting it back after a battery pull (at the time touch comes and goes) I was easily able to recreate the issue.
For example:
Touch = dead, once I plug it into a charger (usb/wall), Touch returns.
Touch = alive, (after it came back during day) Once I Plug in to charge, Touch gone.
There was a point that touch wouldn't return if I had the phone slider closed, with screen unlocked. Wether I was plugging it in or removing to charger.
I hope this makes sense, and really hope its not hardware, as I don't wanna return phone to find out it repeats on a new/refurb one. As this one feels solid in every other dept.
Q's Did palm change how the phone locks..reacts to charger??
If so, god, please fix it!
Post relates to: Pre p100eww (Sprint)

ok, I left work today. in the elevator down to my car i started pandora, bluetooth. Got in the car, docked the phone, plugged in the aux wire to my radio, charger to the phone. Music, couple of calls, music agian, skipped some songs, changed pandora stations, etc...
Got home, undocked the phone, unplugged aux cable and charger, close pandora, turn off the light. Grab my stuff, phone rings can not answer it. Screen now does not work anymore.
Pull the battery twice, no luck. Do some searching and see some post that it is realated to the battery connection and a post that other have got it to work with the charger plugged in.
I take the USB cable, PC to phone and it starts working!! yeah... mess with that batter and no luck. stops working again. unplug the USB from the PC and it is still working. Uplug the USB from the phone, stops working, plug it back in to the phone, not the PC and the screen works again... not really sure what that is about. now it is working with no wire.

Battery and charging issues

I have a DROID X and have been having issues for the last few weeks with my phone staying charged and charging. I have had both my home and car chargers replaced. Everytime I charge my phone it says that it is charging bit the battery level does not improve. When I use my roommates charger it charges fine. Also the battery says I have a certain % of battery left then the next minute it goes down 10%andthat that happens whether it is charging or not. I don't know if a certain app could be causing this or if the phone is junk and I need to get it replaced. Its getting annoying that I have to charge it every night and can't be away from home because I wont have a charger. PLEASE HELP!!!

What app or type of app would you think could be causing the problem? I don't want to uninstall or factory reset my phone...if I wanted to do that I would just get a replacement phone. I do have an ATK on my phone...
From your home screen, press menu>settings>about phone>battery use (unless Moto moved it). This will give you a list of apps with a percentage of how much battery they have used. Also an app called system panel in the market will help you to monitor what is using system resources. I would also personally recommend uninstalling ATK, though not all users would agree with me. Maybe try turning off autokill and see if that helps. I do agree with dirkbonn, though, that it sounds like a bad charger,

Accessory may not be supported error and charging issues with iphone4

Hello,
From past 2 weeks my Iphone4 (say A) keeps throwing error message "Accessory may not be supported" and doesn't charge the iphone after couple of minutes of charging. This happens when device is connected (for charging) to power outlet or to computer (USB port). I tried multiple original iphone/apple cables. The same cable allows me to copy pictures from this device/Iphone4 when connected to computer via same USB cable, but the device/iphone4 does not charge. The same cable and charger charges my other Iphone4 (say B) perfectly fine.
I am really frustrated as to why this is happening.
Searching on internet, it seems lot of people are facing this problem with their iphones and ipad devices and refer this issue as a software bug, which I also seem to think. How can it be the hardware issue when same charging port and same cables allows you to copy your pics etc. from your iphone device to your laptop but does not allow you to charge the same device? Same charging cable works with my other iphone4 and i tried multiple cables so I dont think it's a cable issue.
Any help is appreciated. I was expecting apple products to be better in quality but lately I have seen this issues quite often.

Make sure you are using an Apple approved charger and cable. The best would be the charger and cable that came with the iPhone in the original box.

IPad 3 Syncing and Charging Issue...

Hi I just recently bought a new ipad (3rd gen) in a local apple store,,, an now I try to sync it on my PC via itunes and I noticed that in the batter indicator it says "Not Charging" even though I hooked it up on a USB 2.0 port,,, why is that? I have an iPhone 4s but everytime i connect it to my pC it automatically charge why is that my iPad is not charging????

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Hi all, I have the following question - bought iphone 5c used a couple of days ago and have 2 issues so far - I have problems charging it - the battery would drain to 0% and will plug it in but will not charge, instead after a while the phone would turn on and stay 1% forever. Tried another charger and it charges but when it is off and charging it does not show the percentage bar on the screen. Secondly - when I turn it on, seems like there is weird light from the top and the screen seems to be no very responsive, when the phone is on.
Return the phone and get your money back, Then purchase one from an authorized Apple dealer.

Iphone 4s frequent shutdown and rebooting issue

My iphone 4s goes looses network then restarts or shutdown and start heating up. Requires hardboot to make it functional again. Frequency of restart and shutdown are multiple times a day. Submitted the phone to apple support and they says there is no issue in the phone. Please help

did you take it to an Apple Store? Also, are you seeing any of the symptoms in this article? Not sure where you are physically located, but I've had trouble with mine if I leave it in a hot car during the summer...as described in this article

Random Shutdown and Mooing

I'm curious. Of those who have MacBooks that exhibit the random shutdown syndrome, how many also have the "mooing" fans? And how many shutdowns have occured to people who don't have a fan that moos?
My fan mooed and only turned on once at full throttle since I purchased my MacBook, and it started shutting down after about six weeks. I wonder if the problem involves the failure of the fan to cool the logic board (or some other part of the computer), which at some point fails due to the high head.
For now, my MacBook again works perfectly, but I wonder what will happen in six weeks' time, since I still have the moo.

I have bought a white MacBook at the Farmer's Market Apple Store in L.A. about a month and a half ago. Since last Sunday, it has been randomly shutting down on me.
It has happened both when the computer was cool (just turned on) and when the computer was hot (not alarmingly hot, though). It has happened with the computer plugged in and with the computer not plugged in. It has happened before the computer has gone to sleep and after the computer has awaken from sleep, never with any overwhelming workload.
It seems pretty random to me and, even though I almost never hear the fans, the temperature seems to have nothing to do with it.
For the past two days, the only way I had to turn it on and not get a shutdown a few seconds later, was to press the on/off button for ten seconds, until the light started blinking fast and it emitted an alien beep before turning on. Even so, it usually shut down after the first time it went to sleep.
Now that I am back in Brazil, where I live, the Apple phone service tells me they can't offer me any support (even though I bought it less than two months ago), 'cause you only get phone support for three months in the country where you bought the computer. This after two days of getting nothing but a busy signal from both numbers listed for Brazil in the AppleCare Service and Support Guide.
Granted I haven't bought AppleCare, but this is a major defect and I am appalled that they aren't dealing with this in a more forthcoming way, especially since I am still fully covered by warranty.
I have entered Brazil legally with my laptop, and for a simple lack of assistance and options, I have left it at an Apple Store in Rio for hardware tests. Unfortunately, my computer started up just fine in front of the tech support guy today, for the first time in nearly three days. Let's hope they can replicate the defect and SOLVE IT, godwilling.
But I've looked at many forums and found reports of people having to get their logic boards replaced two or three times, isn't Apple at least acknowledging that there is a problem here?

Random Shutdown and Previous shutdown cause: -x2

Hi,
I had twice "random shutdown" for now. My MacBook is about 4 month old and It happend with about 3 weeks between them.
I tried stress testing it with 'yes >/dev/null' heating it up and cooling it down several times but I could not reproduce the Problem. However, looking at older system.log files, I found the "Previous shutdown cause: -82" lines in there. My question: Some MBs seem to report -72, others -82 as the shutdown cause known as random shutdown but what actually is the difference? Is it possible to guess the time it will take to get it repaired depending on the shutdown cause (which obviously describe two different conditions)?
Thanks a lot in advance and sorry for my somewhat clumsy english;-)

I don't know where you are in Austria, but I took my RSD macbook to mcshark in Vienna, and they repaired it, replaced the case, and returned it to me in one day. That was last Friday and it's been working great since. They knew all about the heat sink problem, didn't even ask for my user name or password, left my hard drive completely intact - they were absolutely super.
If you are anywhere near Vienna, call McShark and make an appointment - they'll repair it quickly for sure.

Random shutdowns and restarts...where to begin?

This is a client's machine.
It is a second generation G5, 17". It passes all TechTool tests. We have the back cover removed to check for overheating. Thus far, we have not been able to duplicate the problem of the shutdowns and restarts...but the machine is essentially idle all day. The processor is not really being used, so it is not an accurate test.
1. Is there are software utility that will put a load on the processor so that we can recreate the issue?
2. Does this have any known heating issues, like the 20" of this series that were recalled?
Thanks in advance for any help.
G5 Mac OS X (10.4.8)

One not uncommon cause of this problem can actually be the very simple matter of a misaligned power cord collar, Bailey's Dad - see http://docs.info.apple.com/article.html?artnum=86817
This might also help to explain why the behviour hasn't been easy to replicate after the move and with the back taken off. Maybe it is now properly seated!
Putting it under load would be a good idea , though. A power supply issue is not out of the question. The SETI "BOINC" software - http://setiathome.berkeley.edu/ - can be used to create an ongoing artificial load. Playing or rendering videos works pretty well (as Miriam has already suggested) too though. So does running "Classic" applications, using the Classic OS9 emulation.
Printing will provide a short term load on the processor and power supply, too.
THe "Rev B" extended repair program that Miriam has linked to only applies to the 20" model , I'm afraid, not the 17".

New Mac Battery and Charger Issue

Ok today I got a new battery from the apple store for my macbook pro. Everything seems to work. As usual with any new battery I wanted to turn my macbook pro off and charge it fully. Well I went to charge it and the light on the indicator was red meaning charging. But all of a sudden the light turned to green. This I know is not correct because I know from when I was in the apple store, the battery was at 56%. So right now I am not charging it because I don't want to destroy this battery like my last one. is this a malfunction with my computer or charger?

If you have a charging problem, it's probably related to hardware rather than OS 10.4.x. So, suggest you post your question in the MacBook Pro forum http://discussions.apple.com/category.jspa?categoryID=190 where other MBP users hang out.

Early 2011 MBP 17 Random Shutdown and Battery Behavior

Hi all, new to the forums here.
I recently purchased a refurbished early 2011 MBP 17' 2.2 Ghz i7 with 8gb and 10.7.5. Out of the box, machine looked great, but I noticed that the power cable was different than the one I had for my early 2011 MBP 15' I have for work. This raised an immediate redflag (buying from a refurb site outside of apple is always a cause for concern IMO) so I abstained from using that charger until I knew a little more. I plugged in the machine and booted it up and everything worked great. The batter was close to 100%, so after charging for approximately 20 min, I unplugged it, and the laptop immediately died. I powered it back on, and the harddrive began to spin for a few seconds, then the same result, total loss of power. Started up again, and I was able to boot into OS X and play around for a bit for a period of time before again, shut down.
For the next few days, same story. I was able to at one point, drain the battery completely and do a full cycle charge. The first time I did this, no change in behavior. Again, a few days later, I was able to drain the battery and perform a full cycle charge, but this time, a major change in behvior. Since the second full cycle charge, I have had absolutely no power problems. I haven't really "pushed" my MBP to see if fully utilizing the CPU/RAM/GPU will produce the similar results I had early, but it appears that everything is working great.
Here a few interesting notes to my situation.
When I was first operating the system (when plugged in, there were no shutdowns, only while on the battery) I pulled up my system report, and noticed that my battery cycle was very low (~5). This seemed odd, because I had opted for a used battery instead of a new one.
Prior to reinstalling Mountain Lion, my volume up key would trigger a few strange events. The screen for briefly get quite bright, then all open applications + the doc and widgets would restart (similar to killing explorer.exe in the windows task manager).
Since performing the fresh install, I have had abslutely no issue with my MBP and I love it, its a beautiful machine. However, as I purchased refurb, I'm hesitant to proceed (I will exceed my return period in ~2 weeks) without knowing my machine is in prime working condition. I have read issues about early 2011 models having issues with batteries and GPUs, but my symptoms were dissimilar to those described by others with those particular issues.
Any thoughts?
I have a genius appointment tomorrow evening for a general diagnostics check, but if others have experienced these issues, I would appreciate some input.
