Shuts Off with No Warning

I've had my MacBook plugged in and turned on pretty much steadily for the past month or so (something I've done before with no problems).
In the past few days, it has just suddenly shut off -- instantly -- a number of time. Doesn't go to sleep -- just turns off. Sometimes it will shut off again before fully rebooting.
I have also noticed that the power indicator is not going above 96% even though the MacBook is always plugged in to a power source.
I'm also using it with an external monitor and mouse.
Does this seem to be a power/battery issue? I would think that even if there were some sort of power blip, it would go to battery. Is this one of those things where it helps to take the battery out and out it back in?
Could it have anything to do with whether the MacBook's cover is open? I've read in these forums that it doesn't need to be, and it seems to work with it closed, but I have a slight impression that leaving the cover open somehow helps?

Note the exact time the issue happens and check your System logs in your Console application for clues to the cause.
It sounds like it could be thermal-related or possibly the battery if it has a lot of load cycles on it.

Shut down with no warning 49% battery left.

Macbook Pro 15".
This is a brand new battery. I bought it because I was told my laptop was shutting down early with no warning because the battery was bad. Well, this is a new battery and it's doing the exact same thing.
I have NEVER had a warning prior to shut down. And it doesn't go to sleep. It completely shuts off with NO warning and I lose anything I was working on at the time.
There is no way I can recalibrate it according to the many posts already about this problem. They all suggest recalibrating the battery by running off the battery and waiting for the low power message. There is no message. And I can't run the battery down because it won't go down past 49%. Or at least that's what the computer is showing.
Since this is not a battery issue I'm thinking that this is a software issue. Something that happened with one of the leopard updates.
So what now? What can I do software wise to repair or update the battery sensing part of my software?

The same thing is happening to me. Again. Last year same thing happened and a new battery fixed it, but going bad again way before it should. Problem started with computer not waking from sleep, and now the sudden shutdowns. I did update Itunes fairly recently, around the start of the problem, otherwise use 10.4.11 and had not updated anything since the last time I had this problem (curious).
There are an overwhelming number of bad batteries for this machine, I would not conclude it is not the battery and I would turn in the one you just got and try another one.
Also there is another reset to try besides recalibrating, since that is not possible, (PMU?) that I cannot seem to find this time. It did not work the last time but wanted to try it anyway if anyone knows of it, I think it involves removing the battery. Please post it if you know what I am referring to.
I was lucky last time because when I took it in to Apple store it shut off right in front of them at 97% charged!

My iPhone 3g is stuck in recovery mode. When I connect to iTunes to restore it shuts off with only 4 mins. left. How can I fix this?

I changed a few settings and now cant get the iPad to shut off with the shut off switch and can't back to the settings icon to change it back. Any ideas?

I changed a few settings on my iPad and now cant get the iPad to shut off with the shutoff button and the button to get to all the icons won't let me get back to settings to change the settings back. Can anyone help?

Have you tried resetting your iPad?
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10-15 seconds).
No data will be lost.

Snow Leopard shutting down with no warning is getting more complex!

I have a series 1 Macbook Pro and have updated to Snow Leopard. As with most other people I immediately got problems with the "battery Service" message. So, having read all the various posts, and tried re-calibration, I bought a new battery.
Charged fully and disconnected adaptor. The machine shut down with no warning at about 85%! I tried a few more times after fully charging the battery and it shut down a number of times - 83%, 85%, 89% and 98%. The battery shows a cycle count of 1. The last time it shut down (89%) I decided to try re-starting without plugging the adaptor back in. The machine started and ran up to the point where it properly started Snow Leopard - when it was about to change from the blue screen - at which point it shut down again. I tried this a number of times and it was absolutely conisistant, doing it every time.
I then had the bright idea of plugging in the adaptor but watching the LED to see what happened. The LED came on green for 1 or 2 seconds, then went red. I then immediately unplugged it again. I then tried to start the machine with battery only. It started perfectly and went on running until down to 15% at which point it shut down, again with no warning. Tried re-starting - it wouldn't! Plugged the adaptor in so that it would charge the battery whilst using the machine. Then, much to my amazement, while the adaptor was still plugged in, and the battery was far from fully charged, the machine shut down - again without warning. That's "it shut down with battery installed AND mains connected". The machine then wouldn't start, with mains connected. It would switch on for a few seconds then shut down again. To get it to start I needed to remove the battery and run it on mains only.
That's where I am at the moment, running 'mains only' with no battery installed. It looks as if Snow Leopard sets the battery monitor / charging hardware incorrectly on the MBP. Once set incorrectly it looks as if it loses itself!
Has anyone else experienced anything like this?

It really doesn't get any better! Well, not a lot. I decided that I'd try yet another brand new battery. I charged it fully, disconnected the mag connector and it ran happily without shutting down - hooray. However, after putting out the message about low power and about to shut down, at about 5%, it ran to about 2% and shut down without warning. It didn't go to sleep.
I then couldn't get the machine to start again. I reset the SMC and still no joy. it would start to run, flash the screen a couple of times and then die. To get it to run I had to disconnect the battery, start it, then plug the battery back in again. Snow Leopard does appear to do something odd with the charging hardware. It appears to leave it in an odd state.
You may be right about Battery Update 1.3, but there appears to be no way of installing it under 10.6.8 - unless you know something I don't!

Hold down home and sleep buttons for about 15 seconds. If you don't see the Apple logo, plug phone into wall charger for at least 15 minutes.

My iPhone 4S shut off with a 62% battery life and hasn't came back on yet. I've charged it and all it just won't come back on at all. Is this a common problem? Is this covered under my 1 year warranty?

My iPhone 4S shut off with a 62% battery life and hasn't came back on yet. I've charged it and all it just won't come back on at all. Is this a common problem? Is this covered under my 1 year warranty?

No it is not common.
Most have no issues.
Have you tried basics from the manual? Restart, reset, restore?
The warranty covers defects. If the iphone is defective, then they would replace it.

MacBook Pro shutting off with battery charged

I have a MacBook Pro I purchased about 22 months ago. About seven days ago, I started noticing the computer just shutting off without warning, even with a charge of 20% or more. Using Coconutbattery my batter still has 62% of it's original capacity with 367 load-cycles. Battery life isn't great, so I was considering buying a new battery, I'd just like to know if other's experience this, and would a new battery solve the problem.
There are no other problems with the machine.

My ibook G4 shuts off randomly without warning when it's plugged in.

I have a ibook G4 (late 2004) running leopard. I recently (a month or so) installed a new HD, since original finally failed. I have been running my ibook on power only for 3 years, since my battery stopped charging.
In the last few days my computer has started shutting off completely without a pattern or warning. I hear a single click as it shuts off.
This began when I was using hulu and wanted to plug the video adapter in as a larger display on my TV. In order to do this, I closed the ibook (putting it to sleep) while on hulu. Plugged in the video adapter and opened the ibook. It seemed that my computer had shut off suddenly when I opened to awaken it. I held down the power button to hard reset it, not knowing if the comp. was off or not. A low-long beep came from within the computer and the sleep button blinked very quickly about 8 times or so(too fast to count).
Ever since then I can't trust it to stay on for any amount of time. Sometimes it will shut off as it is booting. Other times it may run for several hours then suddenly shut off.
I am wondering if some other part of this ibook is dying or if I created an issue with the video adapter? Any help would be greatly appreciated.
Thanks in advance,
Jason

HI,
Try Resetting the PMU
Might want to run the Apple Hardware Test also.

Answer to issue w/ ipod shutting off with older docking station

Since I have gotten a lot of help over the years using forums, it is now my turn to help others with the problem of the ipod 5g showing low battery error and then shutting off. The apple store could not help me, so I took a chance and purchased the scosche home dock adaptor. This fixed my problem for the 5g and I can now listen to my ipod in my hot tub again.

Additional information: My car battery died, which reset the radio and the integration kit. The integration kit worked perfectly for about three days, then once again the two stopped talking with each other. So it seems that the kit may work at the beginning, but then it peters out.

Why does my Macbook Pro keep randomly shutting off with or without the adapter?

I had this problem before that my 13-inch Macbook Pro would stop working without the plug, and then it started resetting its clock to 2000 every time i rebooted it until it eventually died altogether. I found out that my data cable was bad and got it replaced.
Now, it works completely fine except that it will randomly shut off without warning, even if it's plugged in.
I don't know if it means anything, but I'm currently using a Macbook Air adapter.
It's actually shut off while I was typing this post. Incredibly frustrating.

I think (let others bust my chops if I'm wrong) that the MBA uses a 60W MagSafe Power Adapter, whereas the MBP uses an 85W MagSafe Power Adapter. That could be causing problems.

Apple Display doesn't shut off with new Mini

I have a brand new 2009 Mini hooked up to my 23" Apple Cinema HD display.
When I shut down the Mini, the power on the display does not power down.
I used to have this same display hooked up with the same mini DVI to DVI connector hooked up to my late 2006 MacBook. The display used to shut down when I shut down the MacBook.
There is absolutely nothing different in my setup between the MacBook and the new Mini as far as connections and cables as I'm using the same cables.
Is anyones display powering off with their new Mini?
I wouldn't think that the mini DVI out would be any different on the MacBook as compared to the new Mini. But apparently there is unless I'm missing something.
I don't really want to live with this as all of my computers shut down automatically at night using the Energy Saver control panel. With the new Mini, the display remains on all night.
Maybe I should have bought a new MacBook Pro 13 to replace my older White MacBook 13.
Ideas? Suggestions?

I would hate to say that this might be an upgrade issue with recent updates.. I 'used' to be able to power off the monitor (touch the switch on the side and the light goes off) but no longer able to.
And to confuse the issue, the 23" ACD power switch is now acting like the Mac Pro's power switch.. While the Mac Pro is running a lengthy process, I'll often turn off the monitor if I am away for a few hours but now, when I touch the ACD power button, the Mac Pro responds with a "shut down, sleep or log off" kind of query.. Well that is certainly new to me..
Does this happen to yours as well?

Iphone 4s 1 month old Shuts off with battery life remaining!

Just wanted to put this out for others to see.
I bought this iphone online from Cricket brand new in June 12, 2013, didnt activate it till July 9, 2013 and today 8-2-13 I had to take it to Apple to diagnose because it was shutting down by itself even though it was showing 50% battery remaining and would not boot but showed the "battery icon with the red bar inside" indicating it needed to be charged. However, when you did charge it and then booted it, it would show that there was 50% battery remaining since that was the point it shut down at and started charging from that point or at whatever battery %(percentage) it shut down at. Initially it started turning off the 1st week at 5%, then 10%, then 15%, then 20%, then 21% and so on until by the end of 24 days of light use it was shutting off at 50%. I took the phone to Apple and the Apple employee saw the problem i was having and had a technician open it. Apple's conclusion from the store was 1. The battery was working 100%, 2. Everything inside looked original" (It should, it was a new phone, not refurbished). So basically the iphone 4s was defective but he didn't want to say that. The problem was Not the battery but something hardware or software related. They gave me a new iphone 4s to replace mine since it was under warranty for 1 year and thanfully Cricket didn't charge to reactivate the phone otherwise Apple was refusing to take liablitiy for a defective product and pay the activation fee had Cricket charged me even after i spoke with the manager. Hopefully this phone will be ok, otherwise its another trip to Apple.
Bottom line is it was not the battery but something defective with the hardware or software for anyone else that might be having this problem. IF your phone is under warranty I would have them look at it.
Good luck.

The first time this happened to me was at noon and the battey was about 80%, then again about 4pm and the battery was about 53% and again like one hour ago. This is very anoying, i am happy with my new phone but i feel bad about this issue.

Mini 2140 shutting off with any kind of movement or jarring rendering the battery useless

Hello, I have about 260 of these devices and I am running into an issue with the 6-cell extended life batteries.
We have replaced the 3 cell standard life battery with the 6 cell extended life battery. Now for the issues. I have had several of these come to me with the same problem. When a using sets the machine down it will instantly power off. Almost as if you pulled the battery out. Now, once the machine shuts down you can power it back up just fine. Of course it will shut down instantly again if you touch or jar the battery at all.
Now some of them get so bad that the machine will not power on and I have to replace the battery with a new one. Does anyone know what cause this? Is there a fix for this?
I am running
HP Mini 2140
XP Pro SP3
6 cell extended life batteries
I do have 3 cell batteries that we use as back ups. I have never had one of these go bad so far.
They have been in use since August of 2009
Please let me know if anyone else has seen these issuses.
If you need any more info just let me know.

wouldn’t be concerned with this if it wasn’t wasting the battery.
The battery is not being wasted.
Apparently this mini ipod is suppose to have 14 hour battery life
That is the "estimated" time of battery life.
Depends on a lot of different factors.
As a matter of fact, last night ~11 PM, I turned on my fully charged Mini, set it to Repeat All and hit play. I turned on Hold, set it on my dresser & let it go. on & let it go.
It was still running tonight at 8:30 PM. It finally died within the last 1.5 hours or so. 21-23 hours is how long I got out it.
but mine is much less since it doesn’t properly shut off.
It is properly shutting off. Your battery is probably going bad.
Your iPod is working exactly as it is supposed to work.
