Satellite A75-S229 often turns off without any reason

Satellite A75-S229 often turns off without any reason, everything ok with the AC power, the battery is allways remaining 100%. What's wrong? maybe the battery is too old (about 2 years) and need to be changed?
THANX!

Hi
Was the AC adaptor connected to the notebook during the automatically shut downs?
If yes then I dont think the old battery is a reason for the shut downs.
I presume this is a simply overheating issue. Did you ever clean the cooling modules in this notebook?
The notebook is about two years old and maybe a dust and debris inside the notebook could have a bad influence on the air circulation.
I think the professional fan cleaning will help to avoid the random automatically shut downs.

Mac mini turns off without any reason

My Mac mini turns off without any reason. I just want to make a backup with time machine and after a while the computer doesn´t work anymore. I just see the start-screen with all the users and I had to sign with my user password. After the mac restarts, I had to start time machine again. I stopped energy-management, because I thought that might be the problem but not. Time machine should work the whole night, but I don´t want to sit the whole time next to the mac to wake him up every several minutes. What can I do?

My macbook pro won't turn on without any reason?

my macbook pro won't turn on without any reason, is there any solution in this case?

You need to hit the "reply" button on post to whom your responding too, it's hard to tell if your responding to me or someone else.
small button on the side of the computer and didn't lightting up( no reponse at all). is their any problems do think with the battery?
Usually if your battery is dead because it wasn't charged you can do the SMC Reset and then check the Magsafe if it's connected and showing the orange light, then let the battery charge up.
Once the battery charges up, the computer will boot normally and then you have to reset the PRAM, time, date etc.

Satellite C855-1CU switch on itself without any reason using Ubuntu

Hi to all,
I hope that somebody can help, I have a notebook TOSHIBA C855-1CU
I installed Ubuntu 12.10 on a partition and WINDOWS 7 on another partition
the question is : if I turn off my PC from Ubuntu then stays turned off for about 4-7 seconds, and then switch on by it self without any reason!
Knowing that the same thing happens with my friends who have the same notebook .
Thanks in advance.

Hi there
I recognize this. Had the same issue with Fedora recently.
It is most likely a Kernel bug.
You can try the following:
- when running Ubuntu, remove the external power (unplug the AC adapter from the PC)
- shut down the unit.
Does it stay off now?
If yes, I am most certain that this is a kernel bug and is already solved upstream.
If You use Ubuntu 13.04 I believe this is sorted out.

PWG4 12 inches turn off without any warning still 47% bat

Hi
Is anyone have this problem before, whithout any warning my PBG4 12I turn off even if is still have power in battery 40 to 50%, The only way to turn it on is to plug it and it came alive again.
By the way i dont remember wher to set the warning time % of battery,i check in pref sys pwr energy on battery mode see nothing.
Thanks for help

This is the sign of a lithium battery almost on it's last legs, and it's not an unusual indicator. You can charge it up, and somewhere below 50%, it will just go to zero, shutting the computer down. It happens so quickly you don't get a warning. IF the battery stats are still good, you probably have a fair number of cycles on the battery.
Time for a new battery. Recommend either an OWC battery, which has gotten good reviews here, and can be seen at http://eshop.macsales.com/shop/powerbook/battery/g4-12inch-aluminum/ or an Apple battery, although the comments on the Apple web site are not very positive.

Macbook switch off without any reason...

hi there!
maybe that question was asked before and then sorry for this but my bad english don't allow me to look easily for older topics.
so here is the problem:
my macbook (10.8.5) often switch off even if i'm 70% charged (or more) if i'm not plugged. Then i can't put it on if i don't plug the macbook before.
i first thought that the battery was in bad ealth, but it's not (one and half year old, more than 75% of lifetime according to "coconut battery" software.)
I secondly thought that the processor was overheating, but by checking it's temperature, i know its not.
i heard that there was the same kind of problems on the 10.4.8 version generated by a kind of problem of transmission inside the computer (not sure exactly) and apple published a software whitch resolved that stuff. i got it but as it was for an older version, my macbook doesn't take it.
Do you know if there is a newer version of that software?
here is a link of the old one: http://support.apple.com/kb/TS1599?viewlocale=en_US
maybe this is another problem, but i hope not and i wish you can help me.
thanks for reading me (and i hope understanding me!)

Two readings concern me:
full charge capacity (mAh) : 3078
cycle count : 465
That is a very low full-charge capacity, and a very high cycle count. When batteries get older, and their cycle counts get higher, they can report incorrect information to the system about, for example, how much charge is left. Batteries can also become less stable and less able to handle fluctuations in power demands. Apple usually states that their batteries should offer good performance for 300 cycles, and you have gotten many more than that.
I suspect you need a new battery.

MacBook turn off without warning

My 4-year-old MacBook start turning off without low power warning while on battery.
I checked the battery level, it's usually around 20~30% once I plug it back on and restart.
Any one have any idea? I got a new battery last summer, and I really don't want to pay for another one.
The following is the information of the battery and my MacBook.
Model Name:          MacBook
Model Identifier:          MacBook2,1
Processor Name:          Intel Core 2 Duo
Processor Speed: 2 GHz
Version 10.4.11
Battery Installed:          Yes
First low level warning:          No
Full Charge Capacity (mAh):          3989
Remaining Capacity (mAh):          1409
Amperage (mA):          1584
Voltage (mV):          12028
Cycle Count:          152

Your battery info doesn't look bad. Have you ever calibrated your battery? This is necessary not so much for the health of the battery, but rather to make sure the battery and your MacBook are in sync. Calibrating your battery is what allows your MacBook to estimate how much of a charge is remaining. Over time, without calibrating, they can become out of sync. When this happens, your computer may think you have a 20% charge, when the battery only has a 1 or 2 percent charge. Since your computer "thinks" it has plenty of charge remaining, it doesn't alert you or go into sleep... but then the battery just runs out. Here are the instructions for calibrating your battery:
http://support.apple.com/kb/ht1490
You might want to reset your SMC first as this is a fairly quick process and see if that resolves your problem first (although you should still calibrate your battery if you haven't done so):

Computer turns off without warning on battery power

Starting a few weeks ago I've found that my Macbook Pro has been turning off without warning while on battery power. The first time this happened it was after about an hour of use and now it happens within a half hour or less. If I try turning it back on it shuts off before OS X is fully loaded. According to CoconutBattery my battery's health is at 97%, so the battery isn't losing overall charge capability. When I'm on battery power it says I have 2-3 hours of battery life left. Sometimes I notice this will drop between 1-2 hours after 20-30 min of use (if it'll stay on that long) but it never drops and gives me a warning of low battery. It just shuts off without warning. If I press the button on the battery after this happens I do get 4 out of 5 lights. This never used to be a problem. My computer is 14 months old. I've replaced the battery once about 8 months ago (under warranty) because my original battery was losing capacity very quickly. Because 14 months have passed I can't simply get a new battery under warranty. According to Cocoanut Battery and the Finder my battery should last near it's full capacity. I can't figure out why it's randomly shutting off. I have had all the latest updates including the recent battery patch. Any help would be greatly appreciated. I will award "solved" for a solution and "helpful" for posts that contribute to the solution. thanks!

Actually (and fortunately), that's incorrect. Apple extended the warranty for all Core Duo notebook batteries to *2 years* from date of purchase. Details are here:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
Your full charge capacity is fine (as you noted). But one of the symptoms listed on the linked page is +"Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300."+ The word runtime in there applies, so I would call Apple or make a Genius Bar appointment and head into a store. (I did the latter, they replaced mine - free of charge - 15 months after purchase, no AppleCare, and no hassles).
Hope this helps...

Ipod 20GB Won't Turn Off. Any ideas?

It seems everything else works but the darn thing just won't power down. Any ideas?????
Thanks!!!!!!

Are you trying to get it to turn off without running the battery down? Have you tried reseting it?
If you're willing to wait, you could let it run down, recarge it, and see if the problem is gone.

My MacBook Pro turns off without warning

My MBP (13 inch, purchased mid 2010) turns off without warning. It is a 2.4 GHz Intel Core 2 Duo processor with 4 GB Memory running OS X Version 10.9.4. It happens after periods of both short and long use and has been occurring for the last few months. I keep it updated regularly. I have yet to receive a report when I turn it back on that explains the shut down. So far I have reset the SMC and PRAM as others have mentioned that it helps. No luck though. My battery lasts all day, and I don't use my computer heavily. It doesn't feel hot when it turns off either. There is simply an audible "click" and a black screen. Can anyone help explain this? It is getting very frustrating having to constantly worry that it could crash at any second.

So I have an iPad with the smart cover, and it's usually supposed to turn on the iPad when u open it, but it's no doing that for me. Nor is it turning off without pressing the button. What is the meaning of this?

So I have an iPad with the smart cover, and it's usually supposed to turn on and off the iPad when u open it and close it, but it's not turning on for me. Nor is it turning off without pressing the button. What is the meaning of this?what caused it to be this way? Is there someway that I could fix it?

Wait a sec did this just start?
You set up the smart cover function in settings (you did that, right?) so, if you did that and it's failed you make an appointment at your nearest Genius Bar now.

Macbook air turned off without warning?

Hi! Last night my macbook air turned off without warning and wouldn't turn back on until I tried again this morning. A few weeks ago I had my battery and logic board replaced and since then it the screen has gone blue for a few seconds and then back to normal a few times, (in case this is related at all). Is there something I should do to make sure this doesn't happen again.

As you say it is just been repaired I would take it back to the place that repaired it and ask them to look at it.

I was in the middle of using my iPhone 4 running on the latest iOS before iOS 6 and the screen went black but you can see it is still on because the color of the screen is blueish blackish like when your phone is turning off. Any suggestions?

Reset the device by pressing and holding the home and power buttons for 15-20 seconds until the white Apple logo appears.

My nokia 6230 turns off without cause!?

my nokia keeps turning off,
i am reasonably sure it is not the battery as this problem occours while charging aswell as without charging. Also occasisonally, it doesn't turn off completely, just goes onto a white screen and can only be stopped my the removal of the battery.
Has anyone else had encountered a similar problem and can help me?
Thankyou

Definitely agree with this. Sometimes a slightly corrupt firmware might compromise the performance of the phone as a whole. But there is also a possibility that it's a hardware problem.
Good luck

Does anyone know how to change the settings so it will turn off/dim/lock automatically without needing to press the white button at the top all day? I'm draining batter and it's so annoying!

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
- Make an appointment at the Genius Bar of an Apple store.
