MacBook 13" Aluminum battery lights

Finally decided to replace my MacBook 13" Aluminum battery after a few thousand cycles and a "Service Battery" warning. The new replacement battery is not consistently recognized, won't take a charge when recognized, and the machine's battery indicator light row is showing something completely bizarre.
Of the eight lights in the row, only one is lit, and it's not the first.
Ever seen this before? What's the fix?

Thank you for your response, I'm well aware of what Apple supports on the machine that I purchased. I have also come up with the same quesses that you have made along with several more. My question is more of a technical nature. Can it accept 8GB or is there a technical reason that it can not. The cost is not the question, just is it technically feasible?
It obviously supports single 4 GB modules, since that's needed to reach the 6 GB configuration that has been shown to work. I suspect it's a firmware limitation and that it's unlikely that there will ever be an official 8 GB upgrade. A firmware hack would put you a a gray area where you probably don't want to be. At this point it's probably moot because the cost of 4 GB modules is sky high. I've been seeing that they're about US$300+ each.

  • My macbook pro got wet and the battery light is still on but my macbook won't turn on. What's the problem?

    My mabook pro got wet the other night, the battery light still works but my macbook won't turn on and should i just wait for it to completely dry up? Or what should i do to solve this problem?

    Just face facts - if water (or any other liquid) reached you logic board or any other electronic components, you're going to be the victim of corrosion.
    Eventually, you'll need to have the logic board replaced. There are liquid sensors all over your MBP and the techs can tell if these have been activated. I wouldn't turn the computer on at all - if it were me, I would take it to your local Apple Store/AASP and get an estimate for repair. Rice & other desiccates may 'dry up' the liquid, but it won't undo the damage already done.

  • Why SLFM is not enabled for Macbook 13" Aluminum late 2008 model?

    Hi All,
    Does anyone know why SLFM is not enabled for Macbook 13" Aluminum late 2008 model?
    I just found this out after I installed bootcamp and Windows 7 on my Macbook 13" with P8600 2.4Ghz CPU 2GB RAM and 250G HDD after more than a year of using it.
    After I installed the CPU monitoring widget on Windows 7 and CPUZ, I noticed that the lowest Freq that my Macbook operates even with <5% CPU load is only 1.5Ghz and VID @1.0V.
    I installed Coolbook on OSX to confirm what I saw on Windows. I was surprised that SLFM is not visible in Coolbook which is the same result I got from Windows 7 CPU monitoring widget and CPUZ.
    I checked with our local Mac support and they got the same results for all of Macbook 13" Aluminums late 2008 model. SLFM is not visible on Coolbook which means, it is not enabled.
    I tried to install Coolbook on my wife's Macbook Pro 13" 2010, which has the same spec, P8600 2.4Ghz CPU and 250G HDD. The only difference is the memory which is 4GB RAM. There, SLFM is enabled and works just fine, running at 798Mhz @0.875V.
    Can anyone please help confirm if this is really the case for Macbook 13" late 2008 model?
    Because I checked the Intel P8600 Datasheet and SLFM should always be enabled. Otherwise, it will affect battery life as well as long term reliability of the CPU.
    I would appreciate if the Macbook and Macbook Pro owners in this forum can help confirm using Coolbook the status of SLFM in your own Macbooks. You may use any other tool in checking the SLFM and share it with us if you believe it is more reliable and better than Coolbook. Thanks.

  • My battery reads that it is 100% charged. However, as soon as I unplug it, it dies instantly. The battery lights are still functional, and everything else is working fine! What's wrong with my battery?

  • Where can i buy a macbook pro 15" battery?

    Model No: A1286
    Part No: MC721ZA/A
    I have a Macbook Pro 15" which battery is dead. I've been trying to look for a replacement online on ebay and on amazon, and i have found several batteries that are similar, but i don't know which one is right and is compatible with my Macbook Pro. Is there any way to tell which battery is compatible with my Macbook Pro? Some of the ones i found have the correct model number and part number but has a different color. does the color make any difference?
    http://store.apple.com/us/product/MB772LL/A/rechargeable-battery-15-inch-macbook -pro-aluminum (this is one of the ones i found which is a different color and doesn't look exactly the same)
    https://mail-attachment.googleusercontent.com/attachment/u/0/?ui=2&ik=5b3fb14744 &view=att&th=13f2937234228ffd&attid=0.1&disp=inline&realattid=143737337179275264 0-local0&safe=1&zw&saduie=AG9B_P-Kk41uqfm-2SKJao1cxKeU&sadet=1370787981209&sads= lGH1CBtBdWPdW-gVw4LVKeiEKq8 (this is a picture of my battery)

    Your appointment will assure you that you will be seen. Otherwise, they may turn you away and tell you to come back {in a few hours, later in the day, tomorrow, next week}.
    Your appointment at The Genius Bar for an evaluation is FREE, in warranty or out.
    If you need simple replacement parts (such as a new battery) and you agree to have them do the work for a fee, they will attempt to repair it on the spot, if possible.
    The nature of the work done sometimes means that the genius will also be working with another customer on a time-consuming process (that may not consume his full attention) such as re-installing system software. Do not be offended or alarmed. They will continue to work with you until you are satisfied or they have nothing more to offer, but your time there may not be excusive.

  • Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. Thoughts?

    Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. I was under the impression that it would last 7 hours. This is with normal internet browsing and text editing. my brightness is not all the up and bluetooth is off. Thoughts?

    im having the same problems, bought my 13" MacBook Pro last week and the battery is terrible on it, but i googled it and a lot of other people are having the same issues

  • Is there a way to create an AUDIO alert when my MacBook Air (Mavericks) battery runs low (say 10%)?

    Is there a way to create an AUDIO alert when my MacBook Air (Mavericks) battery runs low (say 10%)?  I often miss the visual power percentage in the top bar, so would like an audio alert as well.

    For global alerts, yes:
    There is no need to do anything before the alert appears, and the MBA will not lose data should it go to sleep. If it goes to sleep at 0% you still have several hours to plug it in before it shuts down.
    I wouldn't even bother displaying the percentage value.

  • My iPod shuffle could be seen on iTunes, but it cannot be charged and don't play music. The battery light do not flash at all.

    Like what I mentioned, the iPod do not work, it won't play music and the battery light do not flash.
    But it shows in iTunes, and I could sync music into it.
    I tried to reset all the settings of the iPod, and installed all the new software, but it does not work.
    I don't know if it works before, my friend left it to me. I erased all the data she used before and syncronized all my music inside.
    But it just never worked in my hand...
    I really appreciate all feedbacks! Thanks and please answer this question if you have the similar situation!!

    Are you using the USB docking cable that came with the iPod?  There are separate contact points for power and data, so it is possible for the cable to connect for data, but not for power.  Some third-party replacement cables may be of lower quality, if you do not have the original cable
    However, it seems to be getting power, since the shuffle is operating when connected and you are able to sync when it is connected.  So I think your USB docking cable is working.
    That leaves a problem with the USB port or a problem on the shuffle.
    For the USB port, it may not be supplying sufficient power to charge the battery.  As a test, you should shut down (power off) the computer and disconnect all USB devices, including hub, except for standard keyboard and mouse (if normally used).  If the Mac is a laptop, connect its power adapter (so that it's not running on battery power).  Do this to reset the shuffle
    http://support.apple.com/kb/ht1655
    Start up the Mac, run iTunes, and connect the shuffle to a direct USB port on the Mac.  Any difference...?
    If that does not help, it may be a problem with the shuffle, such as a worn out battery. 

  • Simple battery light question

    When my battery is taken out of the computer, pressing the button on my battery causes the first light to blink. When putting it in the computer and plugging in the power adapter, the first light blinks continuously, and the power adapter's color changes to an orange color.
    Is this normal? Is this just an indication of the battery charging? Or is there a problem with the battery?

    Hi smtlaissezfaire, welcome to Apple Discussions!
    If the battery light blinks then this indicates that it needs to be recharged.
    The power adapter should stay orange while the battery is charging and upon completion will turn green.
    Have you been able to charge the battery until the adapter turns green?
    What do the battery lights do then if you press the button?

  • Blinking battery light when fully charged

    My battery light is blinking (low battery power warning) but the battery is fully charged.  I installed a brand new battery, left the AC adapter on overnight, and this morning had a blinking battery light.  It doesn't seem to be a problem except that I won't be able to tell when the battery really is low?  Thoughts anyone?

    On buying MBP with retina display, one of the Apple genius in the store advised never overcharge it and till date I am acting upon his advice.
    Also, he stated don't put your MBP for continuous charging. Charge it in the same way same as you do for your mobile phone.
    Anyways, I'll keep on looking charged status (100% charge) like what I and other iPhone users do.
    Actually, I take well care of my belongings and iPhone being a premium product, I raised this concern.
    Anyways, Thank you very much for your kind support.
    The genius was misinformed. There is no way to over charge an Apple battery powered device. The charging circuits in the device itself will never allow that to happen. Once the battery is fully charged, charging stops no matter what you do or don't do to the device.
    BTW, this is not an Apple thing. The over charge protection is actually part of the international engineering standards for smart lithium battery technology.

  • Satellite A500 - Battery light flashes when connected to mains power

    Win 7 Satellite A500 PSAM3A-03P00E.
    The battery light flashes when connected to mains power (intermittent fault), when I unplug mains and re-connect flashing stops and battery (high capacity) continues to charge.
    Also when battery light flashes the key board back lighting stays on when it should blank out and if the back lighting is off and the battery light starts flashing the key board back lighting doesn't turn on, all other functions seem to work fine.
    The battery charges and holds charge as it should (when light flashes battery doesn't charge).

    Hi
    Did you notice this issue from first day of purchase?
    Theoretically it could be possible that your battery starts to malfunction
    At the other hand an electronic issue might be possible too
    However, try this:
    Remove ac adaptor and battery. Then press and hold power buttons 30 sec long.
    Then insert the battery and connect AC adaptor again does it helps?
    By the way: is BIOS up to date? If not, perform an update.

    Solved!

    All fixed, the earth contact in the power jack was bent down allowing intermittent contact and limiting current. I bent the contact back up to where it should be and all is good.

  • HT1199 Battery Lights Dim

    So I was ready to play Minecraft when  I resized the window (because the default one is kind of small) and since the last Minecraft (MC) update, the window flashed white and red when resizing. I was resizing it when it froze, and the display froze. Well. I took out the charger, slept it, unslept it, and at last it displayed the white screen, then the login-after-sleep window, and I quit Minecraft.
    But that isn't the question.
    Since that, the battery lights have become dimmer, as in the green lights being duller. Also you know how they usually fade out after a bit? Well, now they just go out without fading, if you know what I mean. Please help! What's wrong!

    You have a 1-year warranty. If you call after 90 days, they ask for a credit card and will charge you if and only if the problem turns out to be not covered by warranty. If your problem is a bad battery, you will not be charged for phone support.
    That said, they will probably ask you to reset the SMC and PRAM to see if that fixes the problem, so you should try that first:
