Macbook pro battery percentage not correct

The percentage will say one thing then suddenly something else. Not sure why.

Resetting SMC may help.

My macbook pro battery will not hold charge

My macbook pro battery will not charge. The laptop will only turn on after it has been plugged in to charge, and when unplugged it automatically dies. When plugged in the battery indicator is green and the top right corner of the screen says "Not charging". I left town for a week with the laptop off and I came back in town and it won't charge. What can I do to fix this?

If you are under warranty call Apple and get a case number.

Retina MacBook Pro Battery Percentage issue.

Hi,
I got a 2.3Ghz Retina MacBook Pro and have noticed that the battery indicator tells me (currently) I have 75% charge remaining. However, when I look into iStat widget, it tells me it's 72%.
I ran into System Inormation under 'Power' tab and divided the total capacity by the one left and it does come out to 72% indicating that the iStat is indeed correct.
Does anyone else have a similar problem? I just find it quite weird. I had to exchange the laptop once for batch of bad pixels on the screen. I really don't want to go to the store again and deal with setting up a new device if it's just a software glitch and not a battery issue.
Thanks,
Paul
ALSO,
I've checked the display for ghosting etc and no issues here. I've noticed that some of you have that problem. Just wanted to give an update on another rMBP.

MacBook Pro battery does not charge

My macbook pro is dead after the battery went flat. Now the battery will not charge, the LED on the power cord remains green, and I am unable to turn on the computer. Any suggestions on how to correct this problem?

When the battery is really dead there are three possibilities:
- Reset the SMC and hope the problem went
- Bring it to an Apple Service Provider, if it's covered under warranty
- Buy a new battery
All if it is the battery, and not something else with the power adapter or the MacBook Pro itself.

Mid 2010 Macbook Pro battery will not charge after plugging in firewire cable shut down computer

I have a mid 2010 15" Macbook pro with Lion installed.
I was running off battery, and I went to plug in a firewire cable, not plugged into anything, and when I inserted it, the computer shut off.
The computer would not turn on again without being plugged into the AC adaptor. The magsafe charger shows green, but the computer says not charging. The battery is showing 57%, but the indicator lights will only light up when AC charger is connected..
I have let it sit off, and plugged in for a couple hours, and nothing chages, and let it sit overnight not plugged in, but nothing.
I have read other forums about the same issue,, it seems like its a common issue, and some have said what it could be, but no one said what it IS.
I have tried resetting the SMC and PRAM, but to no avail.
When i plug in the AC adaptor, the computer immediately turns on (which I find kond of funny), and I am able to turn it off normally, and it will stay off, and I can also turn it on if the charger has been connected from pervious.

MacBook-Pro battery can not retain charge

Hi,
I have this Macbook-Pro 13 inch since 2010. I have very sparesely used it. Recently i discovered it's battery is not able retain charge. I charged it overnight. In the morning i found battery charge is 0%. It was very poor by apple standard for a bettery to die in a sparsely used notebook. What can i do to fix the problem ? Any help is appreciated.
Thanks!

Try a SMC reset and see if it will charge.
http://support.apple.com/kb/HT3964http://support.apple.com/kb/HT3964
You may want to check the info below before, then after the SMC reset.
You can click on the Apple logo in the menu bar holding the option key and click on system information, select power in the left side bar under the Battery Info and check the battery condition and if it is charging, and other stats. Then pull the charger and see what it says.

Macbook Pro battery is not charging but the battery meter is full

Hi guys!
I have a 19 months macbook pro. I've tried using 2 different AC adapter but my mac's battery is still at 0% and the status says "Battery is not charging". I think my battery is dead but the LED battery indicator on my battery shows 5 lights, means its at full power.
I've tried to disconnect the AC cable and remove the battery, then press the power button for 10 sec but nothing change when i start my mac again...i also tried to reset my PRAM ( i think ) by holding a cmdopt+PR while rebooting but it didn't help to solve the problem too. I also have the battery update 1.2 installed on my mac and the results is still the same.
This is my battery info from system profiler. I hope someone can tell me what to do before I visit the Apple store.

Hello,
I am having some strange battery behavior. I bought a FastMac TruePower Battery that is supposed to have extended capacity. Now when the battery dies, i plug in my MagSafe to charge it and it immediately says 'not charging', but then begins to charge. It either continues to charge and gets stuck at 80% or so and reads "calculating" in the menu bar, or just jumps between 'charging' and 'not charging'. The symptoms are very strange, and FastMac already sent this battery back saying it passes all of their tests. I do not want to send it back again because they charged me to send it back to myself even though it still does not work as advertised. I have my original Macbook Pro Apple battery which still charges fine, so i assume it is a problem with the battery based on a simple process of elimination.

SMC Reset and Macbook Pro Battery still not charging

Hi, I bought a new Macbook Pro the Christmas before last (2 years ago) and unfortunately didn't remember to buy the AppleCare. (Didn't have the money to purchase it as I was buying the computer) Anyway, today my charger decided to stop recharging the battery. The battery icon says the battery is charging but the LED light on the charger is not on at all and when I click on the battery status it says "Battery is Not Charging." I've already tried the usual troubleshooting and Resetting the SMC but it didn't work. I also checked the status on the battery and my computer said it was Normal. What else can I do? I really need this laptop for college and the battery has to be usable.

If available, try a different charger.
What does System Report>Power say under AC CHARGER INFORMATION?
Ciao.

Macbook pro battery reports not charging replace now

Hi,
My MacBook Pro reports that it is not charging and the status is "replace now". This is an early 2008 model so is it simply the fact that the battery is due for replacement or could there be another explanation :
I have not used the Mac Book for a few months and battery lasted 3-4 hours on last use.
The battery has only had 30 power cycles, I thought that average should be about 300 ?
Did Apple recall/replace known issues with batteries in this model/date, even so it probably isn't valid now ?
Thanks
Jake

There have not any battery recalls that I am aware of. I suggest you go to the Apple store and have the MBP examined. Your cycle count is very low but the battery is not new, coupled with the fact the MBP warning message is there for a purpose.
Ciao.

Macbook Pro battery is not charging.

Hi,
I recently purchased a replacement battery for my aging (2006) Macbook Pro.
The battery did just fine, but only for 5 cycles. Now, it permanently shows a status of "not charging".
I had started to think that maybe my power block had developed a fault, but eliminated that by going to a local re-seller who kindly let me plug it in using one of their blocks. I got the same status.
Can anybody tell me anything from evaluating my status data, or better still, suggest a fix before I go about returning the battery? I am particularly foxed by the fact that this appears to show the battery condition as 'Normal'.
Here is the data when I look into the 'Power' section of 'About this Mac':

Bad power adaptor.

Since I installed 10.9.3 my macbook pro battery will not charge?

Hi,
New to posting on here. I installed 10.9.3 2 days ago and since then I have had an X over my battery icon. Having checked hardware it doesn't even recognise that a battery is there. Only works now with power lead plugged in. The Macbook Pro is about 18 months old. Would really appreciate any help!

gartonashmol,
have you tried resetting your MacBook Pro’s System Management Controller?

Macbook Pro Battery Is Not Charging but Condition: Normal

Hi,
This question may have been answered but I couldn't find any information about problems with the same symptoms as my own. My 2010 MacbookPro battery is not charging but the green light on the adaptor is green when plugged in. Laptop will die if power adaptor is removed. Have attempted SMC restart but still receiving following information.

Condition is NORMAL but the Cycle Count has been reduced to 0 which it definitely is not after about 20 months of use but I cannot tell what the actual Cycle
Count is for obvious reasons. I'd rather not have to get a new battery but am aware this could be neccessary. Was just curious if anybody else had experienced
a similar problem and if they had it resolved as I cannot get to an Apple store for at least a month!
Thanks for the help.

A new development has just occured. I noticed the light on the adaptor suddenly turned orange. Now the battery is showing the following:

My macbook pro battery is not holding a charge...what do I do?

So, suddenly, literally the last two days, my Macbook will not hold a charge. Within about an hour or two of use, the battery drops 30%. Previously, I could use it for several days before the charge dropped; it would take a week to go from 100% to critical and it was on all the time. The computer is about a year and a half old (so to speak). The closest Apple Store is almost 300 miles away.
Is there something I can do? Install/uninstall items?
Thanks for any and all help.

Install the free Battery Health utility available on the App Store. It will tell you how much battery capacity you have left, compared to the official charge capacity when new, plus will let you monitor in-use battery drain, that will let you learn and use power management techniques to maximize runtime.
For instance, mine shows up after 32 cycles and 7.5 months of life as having 102% of max official capacity (6990 of 6900 mAh), which translates for me to around 6 hours of usage on the average, but which I can stretch out to 7 or 7.5 in a pinch. Guess I got lucky with it, cause when brand new it arrived with a 7160 mAh capacity Yours being a 13" model will show up with a smaller battery capacity.

Macbook Pro-battery does not charge when on standby

Funny thing, I discharged my battery recently and when I plugged my power adaptor I put the computer to hibernation. When I opened the screen the charge was still 15%, same as b4 hibernating. The computer would not charge the battery whenever I close the screen and the problem remains. Anyone had similar problems?

This isn't a normal behavior. Have you verify if the magsafe adaptor was properly connected, i.e. that the amber-LED was on?
