MacBook shuts off without power cord, even when battery is charged
I bought my MacBook in October. I've been treating it really delicately. But for some reason, it will not run without the power cord plugged in (as of yesterday morning).
If I pull it out, it shuts down. If I try to start it up without the cord, it shuts down. It gets about 2-3 seconds before it just shuts off. (It will run in sleep mode without the cord plugged in.)
And for a brief time yesterday evening, it worked without the cord plugged in.
This is my first Mac and I have no idea what is going on.
This is a recently common issue with Macbook Lith-ion batteries.
You have a defective battery, although AppleTech defines defective as a battery below 350 cycle counts. That's the lifetime of your $130 battery, which may average between 6-13 months depending on how you use it.
Some customers have had to buy 3 batteries in the past 2 years because AppleCare doesn't cover consumable items, eg. batteries.
check consumer comments at http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?fnode=h ome/shopmac/macaccessories/power&revw=MA561LL/A
I'm hoping Apple will realize that a $130 macbook battery with a 350 cycle count lifetime, doesn't live up to "Apple" standards. Lith-ion batteries are known to have a 2-3 year lifetime not 6-13 months.
Customers shouldn't have to purchase AppleCare only to realize they have to continuously purchase new batteries every 6-13 months.
This is truly a manufacturer defect in my personal opinion.

My ipad2 won't charge, it's been on 1% all day now. It's plugged in and keeps shutting off. The cord works fine, it's charging my husbands iPad. Any suggestions?
Is this with the power adaptor that was included with your iPad 2 purchase?
The same power adaptor and USB dock connector cable charges your husband's iPad?
If so, sounds like a hardware problem with the battery or something else. Have you tried powering the iPad off and on and/or a reset which is similar to a computer restart?
If so with no change, make an appointment at an Apple store if there is one nearby. -

Macbook pro turns off when taken off the power-cord, is the battery bad?
For a while my MCP when I take it off the charger it doesnt hold the whole time as it should and the battery doesnt last long, and now the past couple days when i take my laptop off the power-cord it will stay on for five minutes then shut down. I dont know what is going on, maybe a bad battery? I got my computer august 2006 . These are my numbers.

isnt the fully charge capacity a little low? what should I do?
thanks!If your MacBook Pro is a core duo model you may have a bad battery and be elgible for a battery replacement. The batteries on the original core duo MacBook and MacBook Pro had the warranty extended and extra year. The details are in this link.

MacBook shuts down without warning during calibration (39% battery power)
My MacBook has been shutting down without warning during recent calibrations (which I've done approximately every two months). Most recently it shut down after 2 hours and 20 minutes on battery power with a battery reading of 39% -- i.e., nowhere close to the 0% of a fully rundown battery.
The result is that:
I'm not seeing the 'low battery' warning dialog before the computer shuts down; and
(ii) I'm not able to save current work and close all applications when the battery's charge gets low, before the computer goes to sleep (because it just shuts down without warning)
Can I do anything about this? Is it just an unavoidable indication of declining battery performance?
My MacBook is 15 months old. Current 'battery information' is listed below.
Thanks. Replies appreciated.

1. I'm not sure how to match the path you listed re: the '1.3 battery update' to what's on my MacBook. Maybe I just don't understand how to interpret it, but I don't have a root folder (or any other folder) identified as 'MacBook.' When I used Spotlight, I also didn't come up with a BatteryUpdater.bundle. A file named BatteryUpdate2007001.pkg was all that Spotlight turned up.
On my MacBoook my hard drive that I boot from is named Mort's MacBook. Yours may be similar I don't know. It is the drive you boot from. Mines shows in finder as the top level drive. The next level in column view. Then you find the System file and go from there.
If your not sure what you named your drive or which one it is click the apple in the upper left corner and then pick *About This Mac* You then should see *Startup Disk* and next to that the name is what you refer too when you look for the folder path I gave.
2. You recommended resetting the SMC. However, the info file you provided a link for says it shouldn't be "necessary except as a last resort in cases where a hardware failure of the power management system is suspected." Does that accurately describe the condition I reported? Also, the problems listed as possible reasons to reset the SMC don't include the one I posted about.
The reason I suggest resetting the SMC is that your changing one of the components that is controlled by the functions of the SMC. The battery is a big part of the system which the battery update changes. To get it to be sure to recognize the new bundle you reset the SMC. The instructions linked are not all inclusive but if you don't want to reset it that is up to you.
3. Similarly, re: the 1.2 Battery Update, it's not clear to me that any of the listed 'symptoms' of a faulty battery apply in my case -- unless what I reported indicates a "+low charge capacity/runtime+." Does it?
The battery update instructions are again not all inclusive. If you don't want to do it that is fine. All I know is you have a MacBook Pro update installed at the moment. You don't have a MacBook Pro. This suggestion of mine has helped many people with problems as reported by you. You do not have to do anything you don't want. That is your choice. Is your battery cutting off at 39% considered normal operating or capacity to you? I personally would call it a faulty battery, but thats just me.
What would be your definition of a faulty battery?
4. Apparently, you had a faulty battery which Apple replaced. I wasn't sure from your message whether you had other things going on that made it clear you had a faulty battery, or only the same symptoms I reported. Were there other power-related problems in your case, or only, as you wrote "the same thing as yours except mine cut off at 28%"?
I guess I misunderstood your original post, everything yours was doing mine was doing except mine cut off at 28% not 39%. I can only give advice on what you post. Are there other things happening that you didn't mention?
My idea of a faulty battery must be different than yours. If I don't get warnings I should and the battery does not work like it used to then that is a faulty battery in my opinion.
If your not comfortable with any of my suggestions contact Apple support and maybe they can help you. Possibly one of the other posters on here can give you different advice that you agree with. Never do anything advised in the forums unless you agree with it. -
MacBook shuts off without warning
The MacBook I use at work suddenly shuts down without warning after running for about 60 seconds. This only happens when the battery is in. If I use the MacBook with the AC power alone, it is fine.
Is this a battery problem or could it be a problem with the MacBook itself?Hi! Well, i work @ the Apple Store in San Diego and this issue has been a rpoblem for the last month or so. The good news is that in most cases the sudden shutdown was caused by a lack of software update of Firmware. So i thought I recommend taht you guys check for updates every single day, its critical to the performance of ur equipment. Dont get me wrong, I said most cases were fixed with the upgrade and there is a possibility that the battery is damaged. For that, I would recommend calibrating your battery about each month in order to have the best battery performance. Instructions for calibration can be found online or in your user's manual. I hope this helps and last but not least, go to the Apple Store if you have any questions, talk to any employee and they will find the help you need! Good Luck and again hope this infromation is useful.

Computer Shuts off Without Warning and with Full Battery
I have been having a problem with my Macbook Pro, where it will shut down completely even though the battery is full.
It is a fairly new battery, because I had it replaced back last fall. When it shuts down, my first instinct is to try and turn it back on. When I do this, it starts up normally, goes to the white screen, but then shuts down again...
However, when I wait about a half hour and try turning it on again, it will boot up normally. It also works fine when plugged in.

Sometimes it is under resource intensive games, other times it is when I am checking email with nothing else open. If I hit the power button after a random shutdown, the machine will not start. I either have to wait for a while, (10-30 mins) or plug in the magsafe adapter.
IF I unplug the magsafe adapter while booting, I will get a random shutdown in the middle of booting. I cannot explain the behavior - I've tried recalibrating my battery, SMC reset, etc.
I put the battery into my other MBP (a 1.83 ghz Core Duo) and it reported a 90% charge and ran for hours without a random shutdown, so I am quite sure that the battery is not at fault. -
2009 Macbook shutting off randomly with over 50% of battery left
Recently my 2009 Macbook has started shutting off, with no warning and 50% or more of the battery remaining. The battery life has also dropped considerably. Is this a common problem? And why is it happening?
How many charge cycles does your battery have? If you are upwards of 300, then you could be getting close to the life of the battery, and it will demonstrate this behavior even though the reading shows better health. Check your System Profiler:
> About This Mac > More Info >…
There is also an open source utility called Coconut Battery that you could download here:

When the battery begins to die it discharges sooner than it is able to activate the script "10% remaining" notice. -
I had trouble upgrading my iPad2 toiOS 5.1.I have had it for about 1 year. I had never upgraded it. I tried a few times but I kept getting a message that I would loose everything on my iPad if I did. I bit the bullet andfigured that I would restore it from the back up on my laptop. Some of the backup files were corrupted. I was unable to retore my exchange email or my notes from the noted app.
Today, my iPad shut off for no reason and I couldn't get it to turn on again, even though the battery was 70% charged. I had to press the on button and home button to get it to come back on.I'm not sure what problem you are experiancing but it would be well worth contacting apple.
If you have had it for less than one year it should be covered under warrenty

MacBook shuts off when power cord is disconnected
2007 White MacBook shuts off (not shutdown) when power cord is removed. Battery shows 98% charge. Any ideas? I plug AC power back in and it reboots when start button pushed. This problem just started tonight.
HELP!Ronan... in your case, it looks like it's just time for a new battery. Your battery should hold a full charge for up to about 300 cycles. At that point, you should expect a decline in the charge capacity. As your battery has over 600 cycles, it sounds like it's had a good life. As you've had your MacBook for less than two years, it sounds like you are possibly using more cycles than necessary. You should try to use your MacBook while plugged in the majority of the time... but occasionally use it on battery (going through one or two cycles a week). A full cycle is a full charge and discharge. For example, if your battery is at 100% and you let it discharge to 90% and then you charge it back up to 100%, that is 1/10th of a cycle. You would need to do that 10 times to equal one cycle. If you started at 100% and let your battery discharge to 50% and then charged it up to full, that would be 1/2 cycle... doing this twice would equal one cycle. The number of cycles is the primary indicator of the life of your battery. It sounds like you are using your MacBook mostly on battery (with over 600 cycles in less than two years). After you replace your battery, try to run it plugged in for the majority of the time if possible. Many people are mistakenly under the impression that they should fully discharge their battery before charging it. This is not the case with Lithium Ion/Polymer batteries. This was the case with Nickel Cadmium or Nickel Metal Hydride batteries (much older rechargeable battery technologies). It seems many people still feel that the memory effect of the older battery technologies applies to newer battery technologies. Just the opposite is true.

I purchased my MacBook Pro 13" from the Apple Store in Tucson, AZ, in mid-January. Since then, every time the Mag-Safe cord is jostled, not even disconnected, sparks fly from the power terminal on the computer, the computer shuts down, and dumps its passwords, as well as the date and time.
Any work in progress is also lost.
I work overseas, and Apple's advice was to give them my credit card number, await shipment of a new power supply and cord, and then, when I return the old power supply and cord, i'd receive a credit. That won't work, as packages from the US to my location take weeks if they arrive at all. There is no Apple Store within a reasonable distance. Or, Apple suggests, when I'm home on leave in mid-June, I should bring the computer to the Apple Store for repair--I have only days in which to do that, but I suppose I'll need to try. My concern is that I'll need to return overseas without my computer and won't be able to retrieve it for months, until my next leave.
This issue shows up elsewhere online. Is there a short in the power terminal in the computer, or on the Mag-Safe power cord, or within the computer itself? It's a known issue, thus I wonder why it hasn't been fixed.Odd, but here's a copy of Page 1 of the links I got:
