Macbook don't reconize the battery

Need help!!
the battery is at 100% charged, but if I unpluged goes off.

Have you tried resetting the System Management Controller? That is a good first step for power related issues such as this.
If that does not work, you might try using a different battery to test. If it works with a different battery, replace the battery.
Best of luck.

MacBook does not "see" the battery. Poweradapter won't charge it ..

Hello, my Macs seem to be at war with me. Today, it's my MacBook playing up. I plugged it in this morning and was surprised to find that it switched off the moment I took the poweradapter out. I then realized that it only works when powered off the power adapter. "No battery" is what the computer thought. I took the battery out and put it in again but nothing changed. I switched the computer off and on again and it nows recognizes that a battery is in but it shows me that it is at 0% and says that "battery is not charging". The power adapter is attached at all times .... It is an older computer (end of 2006), perhaps an old battery, but hey .. is it normal for things to go so out of order from a moment to moment?

Hi, m.g.h. Have you ever tried a different, known-good AC adapter, just to eliminate the possibility that the problem resides there? If you plug the adapter in and the adapter ringlight glows green, turn the Powerbook over and press the button on the battery. The lights on the battery should glow green and stay on if the adapter is working correctly.
I don't see the Battery Info in "About this Mac..." (it's not listed at all; is this because I'm in OS 10.3.9...?
Yes, it is. That info doesn't appear in Panther's System Profiler, so you were right to check it in Terminal.
Your battery is obviously connected to the Powerbook, given the Terminal readouts. That being the case, it would seem that the possible causes include a bad (though new) battery; a bad PMU; a bad DC-In board, if you have a DVI Tibook; and a bad AC adapter.

I dropped my Macbook Pro and now the battery is swollen, should I bring it to the genius bar?

My Macbook Pro fell off my bed (approx. 3ft) and dented the left side of the front left corner on the battery meter. Besides the damage everything seemed okay for a little while until I kept getting a erratic curser track pad. I kept cleaning it thinking some dirty or oil may of got on it or in the edges, but long story short I found out my battery is swollen and thats the reason for the erratic curser. The drop and dent impacted the battery causing it to swell. I feel that I just need a new battery. I purchased my macbook from the apple store and still have applecare. However I've researched online a bit and saw some people posted that if you drop your macbook, Apple will void my coverage. I also read that when people have had a swollen battery and applecare, they just brought it into the Genius bar and they went to the back and brought them a new battery. I've been super nervous to go see them as I've spent the extra bucks on Applecare and did not get any use of it. If anyone has had this issue or knows about it, please let me know!!

Yes !
I would take it in before it gets worse and breaks something.

If the macbook its off and the battery its charged consume electric energy?

hi my question its about saving energy from my house so what if my mac its conected to the electric power the macbook its off and the battery its full charged the question is there is a electricty consume?

Yes. The charger circuit still continues working to keep the battery charged.

Mid-2013 Macbook Air: question about the battery life

First of all, I'm sorry if these questions have been already asked, I've looked around and I've seen some answers, but none that fit my specific case.
I have had this computer since December (Macbook Air, 13'', Mid-2013), I've been using it for a month now. At the beginning, I used to use it until my battery was low (between 10 and 20%) and then charge it. Then I learnt that it's better to keep it plugged as much as possible (I have read this in other discussions and on the Apple page). The problem is that my battery is no longer a 100% of its capacity according to Cococnut Battery. It started with 99%, then back to 100%, then 98, 97... and now it varies from 97 to 98 (right now it says that my computer's current capacity is 6948 mAH). I don't know if this is normal, or if this is caused by the use I used to give to my macbook air at the beginning or by any other thing. I also have 19 loadcycles already. Besides, I have noticed that sometimes it jumps form 100% to 99% of battery pretty fast when I don't have it plugged, and I'm not sure if that happened before.
This is my first time dealing with a macbook and I don't know how these things are supposed to work, and I'm worried my battery might have any kind of problem and that's why itdoesn't have full capacity anymore, since I've been using it for only a month.
Also, sometimes it takes a little while to shut down. It usually takes 2 seconds, but sometimes it takes longer, maybe 20 seconds (first the screen turn white, then the loading icon appears and then it finally shuts down). Is this normal too for macbook airs?
Thanks for the help!

Those are only averages, for purposes of the battery 97 98 99 and 100 are the 'same thing'........theyre all estimates.
Normal on shut down, sometimes you can see a few seconds, sometimes 10, 15 seconds shut down.....depends on what and HOW much its shutting down before poweroff.   Normal.
ON BATTERY USE:
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
*However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.

Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace

My 13 MacBook Pro acts like the battery has died while it is plugged in.

I will use my MacBook normally, it will be plugged in and fully charged. I will leave it on, close the lid and leave it plugged in for the night. The next morning it will still be fully charged (the charger indicator light is green, pressing the button on the left also shows full green dots). I will open the lid and instead of being ready to go right where it left off it has a white washed screen with a loading bar across the bottom. It goes through what normally happens as if the battery has died. It takes several minutes to fully start up before I can use it. Battery indicator is still at 100%. Strangely, this problem does not occur when I leave the computer on, UNPLUG it and close the lid. The next morning it will be ready to go without the white-washed loading screen. There is some, but minimal, battery depletion after that but only do to being unplugged. Otherwise it's fine.
Right now it's in diagnostics overnight at my local apple store. But the apple genius, and several other people I have talked to have not heard of this problem. Any insight? That computer is less than a year old, purchase december 2012. Unfortunately I can't remember the exact operating system. Thank you!

Youve got a wake from sleep issue when powered.
yes, youve got a late 2012 macbook Pro running 10.8.5
Theyll diagnose it and take care of it or replace the logic likely.

Macbook resetting itself when the battery dies.

Hi all I am really hoping someone can shed some light on what’s happening to my Looney MacBook.
About two days ago I forgot to put it on charge when the battery was on 3% and it shut down, so I turned it back on when I had connected it to the power like normal and expected all to be okay. The computer had completely reset itself, time, date, Internet passwords, background everything. I put everything back to how it should and tried to connect to Facebook. The webpage was just the raw webpage, without its style sheet (is the only way I can describe it). So I was like okay that’s weird, and normally after a few refreshes it goes back to normal but it didn’t. It wasn’t because the Internet connection was slow either.
The next day it was still the same, deleted the cache reset everything on safari and restarted which seemed to fix it. I have just let the battery run down again (bad I know) and it did it all over again.
So I am turning to here to figure out what is going on! I hope it can be fixed, as I love my mac too much!
Appreciate any help!
Thanks

The next day it was still the same, deleted the cache reset everything on safari and restarted which seemed to fix it. I have just let the battery run down again (bad I know) and it did it all over again.
If you love your Mac, stop running its battery down the the point that it shuts off.

Dual Monitors with MacBook Pro fails using the battery

Hi guys
I am sorry I am new with Apple and need a help from you guys. I have a MacBook Pro (retina) and connected two monitors to it, using Thunderbolt plugs.
It works fine when I close the lid and one monitor gets the Apple OS and the other I run Windows (VMWare). The problem starts when I remove the power
from it and run using the battery. Monitors got blank display and I have to plug the power back to the MAC, in order to get the OS back. I've tried any combination on the System Preferences/Display and Energy Saver. No go!
Any ideas?
Thank you!

I had the same issue a few months ago when I tried connecting to external monitor, it is only possible to run external displays from a Macbook Pro while the power cable is attached, if you try and connect to external display without having the charger attached the external display will flash your desk top for a second and then your Macbook Pro will go to sleep. Hence connect your charger every time you wish to connect to external display, its not a problem with your Macbook Pro, it's just the way of Apple. Hope that helps.

My New MacBook does not charge the battery at all

Initially, it stayed at 65% with the exteranl power connected all the time. Then it stayed at 0% after I used it without external power. Now it definitly does not start if no external power attached, and sometimes does not start even with exteranl power attached - I can only get it started by taking out the battery, putting it back and plugging in the exteranl power. And the cutomer service ***** - I am retuning it for sure, wasted too much of my time.
MacBook Mac OS X (10.4.6)

Well, I did want to exchange it initially, but the process of getting Apple to admoit there is something wrong with this BRAND NEW system was too painful for me. I never had a similar experience before. Yesterday, after spending almst half day on the phone, I finally got a technitian to admit that the bettery was bad, but the customer return department already closed. (I called both of them a number of times and experienced serveral transfering back and forth, and cutting off). What really pi**ed me off completely is that this morning when I called the custermer return again, the guy STILL transfered me to the tech support WITHOUT listening to me and WITHOUT my permission. Maybe the Apple product IS really that great and worth being abused and treated badly for, but I have never had such a bad experience in my life before, and I do not want to spend a premium price for a system comes brocken and needs half a month to get it "repaired", not mentioning wasting my warrenty on it. So I am going to stay away from Apple's product till they really know how to treat their customers. Before then, I will just return everything they sent me and let my credit company, American Express, a company really stands behand their customers, to deal with them and get my money back.
Ironically, I am the lead quality and reliability engineer who qulified the Intel GMCH for Apple...

Macbook can't see the battery

macbook can't see the battery

Try starting the MB in Safe mode. If the trouble goes away in Safe mode, then there is definitely a problem with the configuration of your main account. If the problem persists under Safe mode, then it could be a hardware problem, in which case you will need to have it serviced.

Don't forget the battery

How many people are now willing to give Apple $80.00 some dollars for a new battery that should cost more like $40.00?

What is happening is that your on-device battery meter is off-sync with the actual battery charge. Connect to your OEM wall outlet battery charger and while still connected and powered on, remove the battery a minute to reboot. After reboot leave to fully charge to 100%.
Thus will reset the false charge reading. You may need to do perform this procedure 2-3 times.

MacBook don't show the login/pin screen after iCloud lock

I locked my MacBook Pro From my iphone But when i try to open it it show the apple logo then it shutdown (without showing where to put the pin code) When I use opetion when booting it it ask for the password I put it right so I have the bootcamp (windows work) but when I choose Mac or recovery it show the logo then shutdown , Any help !?? :'(
I have the OS X 10.9
And Windows 8.1 on BootCamp

I don't know if this would work when you are dealing with a Filevault startup, but this outside thread contains the following suggestion. You would need an external USB keyboard and mouse:
Operate the MBP the same way as you would in "Clamshell" mode. The external display will automatically become the primary. I operate my MacBook that way when at home. I keep the lid shut on the MacBook, have an external USB keyboard and USB mouse attached. Turn on the MacBook, immediately shut the lid and the video will automatically go to my large external monitor.
You must be on AC power for this to work. Will not work on battery only.

Nokia 5130 don't reconize the nokia ringtone .acc

How I can repair this thanks !!!!

Yes, there's probably a problem with your phone. But make sure that these memory cards (which you put on your phone) are not corrupted. You could try to put them on an other phone to see if they work. If so, then your phone has the problem and you will have to take it to a Nokia care point
