MacBook :: Shuts Down When Unplugged - Battery Is Good
Jan 10, 2010
I have a 3 1/2 year old Macbook, my Applecare has ran out. About six months ago my computer began shutting off immediately when unplugged. (Was letting my roomates use the computer, came home one day and it started doing this.) I believe that my battery is OK, it performs between 97% and 99% consistently. When I do the battery test, all of the lights light up.
I've read through the forums and it seems a lot of people are having this problem, but their batteries are bad. What are some options/solutions to this problem? I am willing to invest money wisely into the computer to keep it running smoothly for a while.

My Macbook shuts off immediately when unplugged and will not start up unless it's plugged in. This just started last night...I was using it while it was charging and then unplugged it when it got to 100%, and it immediately shut off. Prior to this, it seemed to be charging and running fine. It also runs fine plugged in.
I did some searching and tried some of the suggestions I found...shutting down, taking the battery out, holding down the power button for 5 secs, and replacing the battery...making sure the connectors were clean, downloading battery update, etc. Nothing helped. I also read an article about how the lithium polymer batteries will just quit suddenly like that instead of running down gradually. So I'm hoping all I need is to buy a new battery. But my question is this: Since the system profiler shows the battery health is "good," does this indicate something else is the problem? Or will it still show it's good after it completely dies?
Here are the stats according to System Profiler:
Charge Information:
Charge remaining (mAh):3955
Fully charged:Yes
Charging:No
Full charge capacity (mAh):3956
Health Information:
I am just now learning about these things, so apparently 1047 cycles is a good life for the battery. I just want to know that this is the only problem so I can order a battery and be done with it. Wish I could run it over to the Apple store and have them check it, but it's an hour and a half away, so if I do that, it'll have to be later in the week or next week. Naturally, I don't want to be patient and wait.

This is a new problem, started immediately after moving the computer gently a foot to the left...
When computer goes to sleep it shuts down.
Then when I press the power button I hear the mechanical click but it doesn't power back up.
Then if I unplug and re-plug it'll start back up. Happens every time like this.
I've, reseated the RAM chips, repaired permissions and reset SDC (SMC? whatever you call it when you hold the power button in for five seconds after unplugging).

I have a macbook mid 2007 that shuts down immediately after it is unplugged from AC. I've tried the battery on another machine and it works fine as well as trying a known good battery in this machine.Also I've tried a known good AC adapter. Other things I have done are run the hardware test which shows no errors, reset the smc and Pram, repaired permissions etc. the battery appears normal in the menu bar and says it is fully charged.Also it Appears in system information as normal.coconut battery also appears normal with 275 cycles.I'm hoping the problem lies in the Battery Connector with Sleep Switch and not the logic board. Anyone had any experience with this problem?
One other strange thing is that after unplugging the AC the system shuts down immediately, but once you plug it back in it starts without the power button being pressed.

I used Bootcamp to install Vista on my Mac Book Pro 2.4 Ghz (April '08). It has been working very well until Dec 2008. While running a PC game on battery, Vista operating system would just shut down unexpectedly. If the machine is plugged in, it would work fine. Currently the problem is getting worse; when I boot up into Vista on battery, it would shut down in about 2-3 minutes.
Initially I thought it was a battery problem. I booted up into Leopard and checked the battery information in System Profiler. I didn't see any problem. 332 cycles and condition is "Good." In addition, Leopard works just fine on battery.

I usually use my laptop at a desk plugged into an AC outlet. Well I was going to be away for a week, so I unplugged it, when I came back, the battery went from 97%, not charging to 12% when I booted the laptop up again.
Also, can one continue using a macbook laptop if the battery is dead, but run it through or plugged into an ac outlet all the time?

I was sick of the battery life I was getting on my 15" Macbook Pro 3,1 (early 2008 model), so I went to the apple store yesterday to get a new one. I was over 400 cycles, so I had to just buy it, they wouldn't replace it for me. I expected that, so no big deal. But I wanted to treat this battery right. I got home, charged it up to 100%, let it sit at that for a few hours, and then let it drain overnight and rest at empty for a few hours. This afternoon, I plugged it back in with the intention of letting it fully charge and thus complete my battery calibration, but at around 40% charged, the cat yanked the charger cable out from my laptop. And then a little bit later, my girlfriend did it again. So, has my time been wasted here? Battery calibration is such a pain in my rear. i hate it. I use my laptop often and expect it to be available to me whenever I need it, regardless of how many other computers i own. I really don't want to deal with it again in the near future. And I may not.

I've tried two brand new adapters and neither work after my MBP is unplugged for a few hours and then plugged back in. Eventually it'll work again, but occasionally it doesn't acknowledge the power source. Will AppleCare cover this?

I have an early 2011 MacBook Pro 15 in. that i got in May of 2011. When i unplug the power adapter it works fine, but at about 80% battery it shuts off. i go to turn it back on and it acts as if it is dead, i press the power button again and it turns on without problem (although the date and time at first is messed up). What is wrong? I recently had to get my hard drive replaced 2 months ago and it has been working fine until yesterday.

So I usually keep my UMBP plugged in at all times. It unplugged by accident and went to 99% so I left it unplugged but literally less then maybe 7 minutes my battery is already reading down to 92%. Brightness on screen is set all the way up, if that has anything to do with it.

Firstly i have a MacBook 10.4.11 that is somewhere between 2 and 3 years old. I have had no problems with the Mac up until yesterday. Yesterday i was charging my Mac and everything was fine but i noticed that the MagSafe Adapter was lit up Green, even when unplugged from my Mac. I shrugged it off until this morning when i realised that when i unplug my adapter the Mac just turns off and won't turn back on until i plug the adapter back in. I have seen different threads about it being a battery problem or a charger problem but i am not sure where to start as most of the threads say that their Battery Icon on the Mac screen has a black "X" through it. Mine just has the Forks in the battery icon and where it would have a Time or % of what is left in the Battery, it just has a (Calculating...) and when i click to see how much it has charged, it says 0%
I also downloaded Coconut Battery and here is what it says:
Current Battery Charge: 0 mAh
Maximum Battery Charge : 5093 mAh
0%
Current Battery Capacity: 5093 mAh
Original Battery Capacity: 5020 mAg
100%

My 10 month old Macbook Air 13" battery behaves weird every 4 weeks. When unplugged the MBA switches off suddenly without a warning even the battery is still more than half full. Plugging it in it tells it takes 20 hours for a full charge but never gets full. After unplugging it crashes after some minutes again and goes dark.
The battery' got 178 load cycles and 5675 mAh out of originally 6700 mAh (84%). Did several SMC resets and PRAM resets. I even reinstalled Lion from scratch without changing the battery's behavior. Calibrating the battery isn't possible because it does not discharge but crashes. I tried three different power adapters.

My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.

I have a 13" 2.4 GHZ white macbook that I bought in march of 2008. About 4 months ago I all of the sudden started having problems with battery life. It was very abrupt. I used to be able to take my macbook and sit through 3 classes or more with no trouble in regards to batter life. Then suddenly the battery would drain within a few hours. It has remained that way since.
I've spent the last month or so looking around forums and other places to try and find someone with a similar problem and possible solutions. As a result I've discovered that my situation seams to be somewhat unique.
Using cocoanut battery I tested my battery's capacity and it remains at a solid 98%. How can my battery still be at 98% capacity and have such a short battery life? I also seam to be losing charge while my macbook is closed. How and why does that happen? If I leave my macbook closed for a day or two it can lose up to 25% charge just sitting there!
I've tried loads of things including turning off unnecessary things such as sharing and bluetooth and calibrating my battery, all with no avail.
What is going on?? My battery is too old to be eligable for a recal and I'm not paying $30 just to have a phone conversation with a "Genius". If anyone has any idea what's going on and any possible advice, I would greatly appreciate it.

My Powerbook G4 only turns on if the battery charger is plugged in, and if I unplug it, the computer shuts off. On the menu bar, it says charging. I know the battery has to be full. This just started happening last night. Also, I just had the hard drive replaced and I've only had it back for a couple weeks.

I made the mistake of unplugging and removing the battery from my iBook while in sleep mode, to reinsert a screw I found on the floor. Now at startup it's stuck on the blue screen. I've tried several resets, icluding shift-command-option-power, zapping the PRAM command-option-P-R which got my "startup sound" back, which I let chime 3X, I reset the NVRAM, single user mode confirmed the clock was reset (to 1904) and an fsck said the system "Appears to be OK." I've had no luck with "safe boot," I have no reset button and no OS disk to boot from. Verbose mode prints up the same 10 lines over and over "(error) imprt: importer start failed for 89, invalid destination port, no such file directory, run loop could not be started." It's a 14" iBook G4 running OS 10.5.6. I don't mind if files are lost-there's nothing important on there.

Is it strange that my MacBook now just shuts down when it runs out of battery instead of just going into sleep mode? It's about two weeks old now. It used to go into sleep mode, but now it just shuts down once the battery is down. Also, I had the most wonderful experience with Apple. My first macbook (three weeks ago) had a small chip on the screen. When I finally noticed it, I thought it was a large piece of dust so it wasn't too terrible. I tried to exchange it at the local store where I purchased it, but it had already been four days and I had cut out the UPC for the printer and ipod rebate the day before and sent it out. So they recommended that I go see a mac genius and see if I can get the screen replaced because I could no longer exchange it or return it (risk losing my rebates).
So, a bit upset that I was too prompt about getting the rebates in, I scheduled an appointment with a genius. When I spoke to him, he just went to the back and got the manager. The manager said instead fixing the screen, he'd liked to give me a new macbook and instant reimbursement for the ipod and printer! (the rebates I sent in will be rejected since the mac has been returned). The new macbook I noticed has a much louder superdrive seems to be working hard every time the computer wakes up and when I open it, but that definitely beats a chip on the screen. But now it doesn't go to sleep after the battery gets low, but instead shuts off.

My MacBook shuts down on random percentages when used on battery power. I can only use it for FIVE minutes before it shuts down. And as I said, it shuts down before the battery runs down to 0%.

I want to calibrate my battery -- is there a recommended app for just chewing away to make the process faster? Do people just play movies over and over again?

I have a 2010 13" MBP that will shut itself off instead of going to sleep when the battery is drained. I tried recalibrating and resetting the SMC, as well as disabling hibernate, but the same thing happens. The computer is barely a month old. Anybody else with a 13" experiencing this? I posted this issue on the Apple forums and someone replied stating that they heard Apple is looking into it, but usually occurs with i5 and i7 machines.

My Macbook Pro keeps shutting down before I reach zero percent battery and often when the battery still has 25% left. I am wondering if this is a software issue that may be fixed or if there is something incompatible with my hardware. I am running 10.6.4 with a 2.16 GHz Intel Core Duo, 2 GB 667 MHz DDR2 SDRAM memory bought in April of 2007. My mac was originally running Tiger, but a few months ago I updated to Snow Leopard.

I have a 1st revision Macbook Pro 15" that's about 2 years and a few months old, and all of a sudden the battery will not provide power past approximately 76%. As soon as the the battery displays, 75% or 76% of the charge remaining, the laptop shuts off completely, does not warn me that my battery is low, and does not sleep or save the contents of my RAM - nothing it should be doing. The battery is only at 149 cycles as of today, and I don't have any sort of AppleCare plan. Is this something I can get replaced under a warranty, or would I have to shell out for a new battery? And is it even worth it?

Recently my battery health has dropped to 21% with only 79 cycles. I have tried calibrating the battery and have always done it at least once a month. Just this morning I was running on battery power and it shut off with 65% of charge left. I'm off to college in a month and am wondering if Apple will replace my battery even though I'm not under warranty.
I would take it to an Apple Store but unfortunately the closest one is an hour and a half drive away. Should I try calling Apple?

I own the first 'remolded' revision of the Macbook released in '08 (5,1), and have had it for over a year now. Recently though, after 10 or so minutes running off just battery power (fully charged), it shuts down unexpectedly. It doesn't say the battery is low, or near low, it just shuts down. It's really annoying, I have to use the charger wherever I go. I really need my laptop so I don't really want to take it to an Apple Store and have to wait a week to get it fixed, unless it's really necessary. My software is up to date. Any ideas on what my problem is/how to fix it?

For the past few days, my mid 2012 15" rMBP has been powering down or sleeping while in the middle of performing tasks, and more importantly when it's ABOVE 15% charge. Just today however, I now have a red battery indication at 52% and holding.
At the time, I had an external monitor plugged into the thunderbolt port closest to the ac adaptor port. I was running Adobe Lightroom and Photoshop, but nothing else, and was not connected to the internet. I had turned wifi off. My problems continued until I plugged in. Once on a full charge, I unplugged and the same thing happened all over. Numerous times. So, I disconnected the external monitor, and thought that solved my problem. The next time I used the computer, I put the external monitor into the other TB port and did not have any issues, however I wasn't using the rMBP as extensively.
Today, again while performing tasks such as importing/exporting images with LR & PS, my laptop shut itself down. It runs warm, and fans are purring like crazy, but that's normal for the work I'm doing. Prior to the shut down, the battery read ~24%. I plugged in and woke it up. No external monitor is attached today. I am not running any other programs besides Chrome at the moment. I noticed a red battery light at 52% and it has not changed. Option clicking the indicator shows a "normal" condition.
OS 10.8.5
2.6 ghz intel i7
16 GB 1600 MHz DDR3
250 GB SSD (with ~25GB free)
NVIDIA GeForce GT 650M 1024 MB
I have had a Speck hard shell case covering the laptop for a few weeks, but no issues until this week.I am a pro photographer who shoots tethered on location and carries my rMBP around on assignment. It has never been dropped, or damaged in any way.
This is my current system info:

I have a 13-inch Macbook, Late 2008 model, using iOS Mavericks. While on battery power, the laptop will randomly just turn completely off, despite still having plenty of battery power left. I know it's not a calibration issue where the battery is dead but appears to have charge left, since I'm able to turn the computer back on again and continue using it.

I have a macbook pro (early 2011) And it went flat two nights ago whilst watching a movie. It was plugged in but I've been having charger issues. Anyway, now that it's fully charged, whenever i turn it on it gets to the apple logo with a progress bar (restoring the previous session maybe?), but then shuts down. I've tried a few times and its the same everytime.I suspect that it's trying to restore the last session (the progress bar - I cant recall whether that happens normally) and running into problems because of the flat battery episode. Can a session restore be cancelled?
I can still boot up the windows partition by pressing the option button during start up, its just the mac partition that wont boot. Also, I am still running Snow Leopard (what it came with, though with all updates).
