    Get your MacBook serviced. The best way to fix your Mac.

    Did you try resetting the SMC? If that doesn't work, you need to take your computer into your local Apple Store or AASP.

    Is there another way to fix it without getting it serviced?

     

    There was an X on the battery icon in June/July , but somehow the X was gone in early august.

    But Then the X has now returned.

    Did you try the SMC reset? It's mentioned in the article that Carolyn posted. If that doesn't work then you're simply going to have to have your machine serviced.

    Again - did you try the SMC reset? If that doesn't work - again - you're just going to have to have your machine serviced.

    Shut down the computer.

    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.

    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.

    Release all the keys and the power button at the same time.

    Press the power button to turn on the computer. 

    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

    I have the same problem.. X icon.. Battery indicator LEDs are not showing anything.. we might think battery is bad.. but while booting with AC adapter.. if I remove the plug.. it boots and work with battery fine.. but if I reconnect the AC adapter it goes to sleep mode or maybe just LCD shuts off.. I'm sure of it.. im suing mid 2009 version and I'm gettin a 3 1/2 hrs backup until yesterday.. I was replacing corsair RAM 8 GB one and for the battery connecter.. I use flat screw driver to lift it.. saw a tiny spark then.. thinking thats the cause of all this.. physically everything is fine.. except I need AC adapter to start the laptop.. I wonder if we'll get the exact reason of this anytime..

     

    By the way tried everything.. SMC, NRAM.. those things etc.. nothing solves.. just learnt living with it..

    I'm having the exact same problem.

     

    My MacBook Pro is 8,2 and I'm running OS 10.8.2

     

    A couple of days ago I first notices the X that shows that there is no battery. Strangely enough, the problem disappears and then it comes back again.

     

    I have tried the SMC reset with no luck.

     

    In one of those opportunities that the battery was back on line, I was able to use Coconut to check it. It said that the battery was at 90% of its total capacity and charged at 100%.

     

    I did noticed that when this happened, Kernel task would go crazy and start using CPU at 300%. Some people say these two problems could be related. http://www.rdoxenham.com/?p=259

     

    Any ideas ?

    OK..... after trying things like checking permits, reseting PRAM, checking the HD, etc, I decided to open my MBP and do some cleaning just in case this could be the cause. My MBP temperature has never been high so I didn't think this was going to do a difference.

     

    At first sight, the inside of the MBP didn't look too dirty but when it was time to dust the fans, a lot of junk came out. Took out the memories and also dusted all the contactors.

     

    Closed everything, started the MBP and guess what.... my battery is back and the Kernel is working fine. I even notice now that my memory is not leaking as fast as before. Hopefully the dust was the cause and that the fix will last.
