Macbook pro shuts down at 15% battery

ok so my macbook pro shuts down at 15% battery by it self without warning just started happening yesterday i got this model in october 2009. Need to know if i have to get a new battery confused with what is wrong with it any reply would be greatly appreciated

In System Profiler/Power what does it say about the Cycles and Condition ?
Reset the SMC (System Management Controller) and re-calibrate the Battery (you should re-calibrate every couple of months).

Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks.

My Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks on the left side. I am running Lion. How do I get this to charge and turn on? Thanks

If your model Macbook Pro is the calibrating model, let the battery calibrate.
If not, and are still under warrant or have Apple Care, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

My MacBook pro shuts down when the battery drops down to 85% charge

I have a 15inch MacBook Pro Model 1.1. When i run it on battery it always shuts down when the battery gets down to 85%. Does anyone know how to take care of this problem so that i can use the battery for longer?
thanks!

WHAT DOES IT ALL MEAN??

That many cycles is amazing service. A battery that consistently shuts down at about the same charge level percentage every time probably has a bad cell (that info came form an Apple technician) and needs to be replaced.
It's given you far longer service than many of us get, and may be a new record around here for cycle count!

Macbook Pro shuts down with 40% battery left... does not just go to sleep

Hi,
Our MacBook Pro has started to shut down with about 40% battery left. After it has shut down, I press the button underneath the computer and 2 our of 5 lights light up on the battery. I wouldn't mind if it just went to sleep but I totally have to restart it and lose everything I have been working on when it died. The computer used to go to sleep when the battery got to 0%, then I could plug it in and keep working.
I don't know if it's a software issue or a battery issue or a firmware issue.
Any tips would be MUCH appreciated.
Thanks a lot.

I have read so many articles across the internet with people experiencing this problem. This is the conclusion I came to.
I could not calibrate my battery as my system would hard power down before it got anywhere close to draining the battery entirely. The last 10 cycles on my battery were attempts at calibrating. The most common cause would be because the battery in our macbook pro does contain something close to the charge being reported by the computer, but cannot deliver it. Your fuel gauge is probably not incorrect, especially when the leds on the battery itself show a charge that should be capable of running the machine. Even if it is not calibrated correctly. The internal resistance of the battery itself has compromised the batteries ability to deliver the amperage necessary to run our machines. After finally realizing this, I turned my screen brightness all the way down, and sat all my power settings to max battery life without allowing the machine to go asleep. Then, I went to sleep myself =). In the morning it appeared as though I had a successful calibration and the machine did not power down hard. Depending on how bad of shape your battery is in, this may or may not work. Either way, it didn't matter much. Even with my fuel gauge being correct, if my screen brightness was cranked up and I was doing anything somewhat processor intensive, my battery failed to provide the needed amperage and powered down my system hard again.
The battery really does have the amount of power it says, it just cannot deliver it as fast as needed. At a slower rate, it will work. A replacement battery is needed. I cannot explain the strange jumps/dips in storage capacity but would guess these numbers are a guide, and more than one environmental factor can change this number. Also, once the internal resistance builds up inside the battery and the inability to calibrate happens, it compunds the problem.
My machine is a first gen intel macbook pro. A few months after I bought it, I had battery problems and apple replaced my battery. My machine is 31 months old, it's battery is somewhere around 27. I tried to get apple to replace my battery and they told me no. I was 40% healthy @ 207 cycles. Many people complain about this but it seems reasonable to me, I didn't argue. I do believe my battery failed prematurely, however, it was due to a few factors and I do not think it was the batteries fault. My machine was one of those nice overheating first generation macbook pros. To make the matter worse, one of my internal fans stopped working. I knew this as my istat pro program showed me 1 fan @ zero rpm. I figured I had applecare and had work to do, so continued to use the computer for several months. I did quite a bit of video encoding and processor intensive work. When I would get to work in the morning, my granite desktop was really cold, however, after a half hour or so with the macbook pro running the heat would dissipate through it and warm it up nice and comfortable! lol, some may not think this is funny, but it worked well for me. I frequently had over 180 degree cpu temps and the bar above the keyboard being too hot to lay your hand on and keep it there. I am sure some of this excess heat contributed to the premature failure of my battery. The type of batteries in our machines are killed by heat, charge amount, cycles and age. Probably in that order for most users. So, can I blame apple because my unit ran hotter than it should have because their fan failed! eh, maybe, but I am happy with this laptop overall. I have never had a single laptop for more than 15 months and have had this one for over 30 now.
I ran across this site somewhere, it may have been another user on these forums, I cannot remember. http://www.batteryuniversity.com/partone-19.htm On this page, it talks about our batteries, the effects of heat and level of charge in combination with age. At 77 degrees F., charged to 100% (which is very typical of our machines, or close to it) after one year the battery is 80% as good as it was when it was new. At 32 degrees it is as 94% as good as new after one year. Jump up to 104 F. and the battery is only 65% as good as new after 1 year. Sometimes my computer is running for days and sometimes the environment is warm. Add that to the heat produced by the machine itself and I bet the battery sustained 100 degree temperatures for long periods of time. Just for fun, at 140 degrees and 100% charge in our lithium ion batteries, after only 3 months the capacity is only 60% of its new capacity.
Anyways, that is my battery story. Sum up. The inability to calibrate is due to the batteries increased internal resistance and inability to deliver the charge at a rate needed by your computer even though it appears healthy, or somewhat healthy. You may be able to calibrate by making your laptop drain less power, turn screen brightness all the way down, turn airport & bluetooth off, let hard disk sleep, and let it go. But that will not stop the hard shut down problem, although the fuel gauge will be more accurate. Think of it like this. a 100 gallon fuel tank on a car full of gas. The fuel gauge is correct, it is full. However, the fuel line connecting the fuel tank to the engine is made of a space age material that shrinks as it ages and is exposed to heat. Eventually the fuel line shrinks to the size of a coffee stirrer or small straw. When the motor is turned off the fuel seeps into the small straw. Start the motor, it begins to sip the fuel from the straw. Rev it up (encode video), the motor demands more gas but cannot get it. The motor stalls out (your computer shuts off). Same idea somewhat. Sorry so long

My 15" Macbook Pro, shuts down by it self (Random occurrence).

My 15" Macbook Pro, shuts down (randomly) by it self, some times it will not turn on, and some other times (very rarely) the fans go on “very loudly” the second I turn it on. But the computer, does not turn on at all, even with the battery fully charged and the fans runing full blast.
Some other times, it will not wake up. It will only turn on or wake up if connected to the power adapter, even if the battery is fully charged.
I have already reset (a couple times) de firmware, the smc and he pmu and the problem persists.
Al this goes on randomly and unpredictably. Some times it works just fine for 4 or 5 days and the suddenly something happens.
I also think that some times the computer runs extremely hot.
PLEASE HELP!!!!!!

15' MacBook Pro Mac OS X (10.4.8)

I have the same thing happening with a new macbook I bought my wife and I called apple today and after going back and forth between apple care and apple customer service they are shipping me out a new replacement macbook as it is less than 30 days since I bought it. I am waiting for their email with the Fed ex info so I can send this one back and then they will send out the new one.
If it is still in warranty I suggest you call Apple customer service and let them know how bad it is and insist on a new one!
This one also reboots at the slightest movement and it took me several tries to finally log in on it tonight to delete all the user accounts before I send it back!
Hopefully the replacement one is glitch free!

MacBook Pro shuts down when i close the lid

Hey,
My MacBook Pro shuts down when i close the lid.
It started to do this one or two times, but now it is every time.
I have the latest battery update, so this should not be the issue here..
Any sugestions??
I have started to suspect the it might be some faulty conecctions or somthing..

If it's unable to go into the proper sleep state for some reason then it will do that.
Run /Utilities/Console and click 'All Messages' top left then close the lid, wait a minute then open it again - if it's shut down then reboot and open Console again and check the latest log lines looking for 'sleepimage' - it should give you an indication of what happened/didn't. If you're not sure what it all means post _just those lines_ here.

My macbook pro shuts down automatically

Hi,
My macbook pro battery condition has been showing that it needs to be replaced soon. Ever since I knew my battery was weak, I started using my macbook by always connection it to the power adapter that way the power source would be from adapter. Since last two days, while in use macbook pro shuts down on me automatically. It never said shutting down or anything like that. The screen just went blank instantly and when i checked the battery indicator lights, all of the battery is drained. When I presses the power button it started and then instantly shut down again. After few mins of repeating, I am finally able to see that my computer is getting turned on. But this issue repeats almost on a daily basis since the last three four days. Even if my battery went bad, I should be able to use my computer by connecting it to the power adapter, right ? or do I have to mandatorily replace battery for my computer to work ? please help.

On starting up, my macbook pro shuts down after 25 seconds of booting up.

Hi there. On starting up, my macbook pro shuts down after 25 seconds of booting up. The time bar comes on for a while before it simply goes blank and switches off without any notification. Battery iappears charged. Could it be a virus? Help please!! O

Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

My girlfriends Macbook Pro shuts down at the Apple Logo....

My girlfriends Macbook Pro shuts down at the Apple Logo....
1)I start the computer
2)It loads to the apple logo
3)A progress bar shows and loads about 5% then it dissappears and a few seconds later the macbook pro shuts down.
Any solutions?
If not, is there any way for me to reinstall the os without losing any files such as(any of her pictures, music, etc)?

Hi S,
See if you can run Repair Disk: Boot frominstall disc (insert disc > restart > immediately hold down c key andkeep holding it until you see “Preparing Installation”) > at first screenselect the language and click Continue > click on the Utilities Menu in themenu bar > open Disk Utility > select your HD in the panel on the leftside> click Repair Disk at bottom of main window. Run this at least twice,and keep running it until it says “appears ok” twice in a row. If that doesn’thappen, you may need a stronger utility such as DiskWarrior or if the directoryis damaged beyond repair, you may need to reinstall the OS, or you may have a damagedHD (repair utilities can only repair the directory structure, not the HDitself). When this is finished, quit Disk Utility, quit the installer, andrestart. Once booted normally, go to Applications > Utilities > DiskUtility and run Repair Permissions.

Macbook Pro shutting down. Hardware error code 4MEM/62/40000000:0x7f537f90

Macbook Pro shutting down. Not the same action making it shutdown. Anywhere from being online to attaching a photo to an email to working in Word or Photoshop. Even after it's closed and not being used. I come back to it being shut off and saying it had to restart because of a problem. I ran the Hardware check and got the Hardware error code 4MEM/62/40000000:0x7f537f90.
I must say I am quite disappointed. I have used Mac for work but had a PC since day one, and I JUST got this Macbook Pro in Dec. I was delighted that Mac usually didn't have as many problems with viruses etc as PC. And now last couple days, constantly shutting itself down. The closest store to me is a few hrs away. I am in South Dakota, store is in Minnesota Any help would be appreciated.
