    Hi Macrumors

    I just godt a mac, and switched from windows!
    I bought mine used, but the seller said there was nothing wrong with it.
    He also said the battery was changed to a new one, before he sold it to me.

    Here are a some specs:
    15", primo 2011
    16 GB 1333 MHz (to PS and After Effects)
    Processor: Intel Core i7 @ 2 GHz (without turbo)
    180 GB SSD
    Systemversion: OS X 10.8.3 (12D78)
    Kernel-version: Darwin 12.3.0

    My battery and Kernel_Task is messing up! The battery sometimes work, and say it's in okay condition, but mostly the indicator flashes 5 times, there's a black X on the battery icon, and it says it needs service.

    It's weird.. it's like it can't detect there's a battery. However, sometimes it does!

    Battery Specs:

    Cycles: 3
    State/condition: Normal
    Battery installed: Yes
    Amperage: 1280
    Volts: 12539


    The kernel_task process also sometimes slows the computer, and getting up to 600% CPU-usage... i THINK it's related to the battery problem.
    Also when it's detecting a battery, I can pull the charger out.

    I've tried these:
    Reset PRAM
    Reset SMC
    Turning on and off a lot of times

    I'm running out of ideas! HELP!

    Regards,
    Jonathan

    Run Apple Hardware Test and see if you get any errors.

    Do so by holding the D key at startup.

    Based on the Cycle Count, it appears probable it is a new battery. It also means the new battery did not fix the Battery Not Recognized "Black X" you describe, and the next step is to replace the logic board (seems to be a blanket recommendation). I suspect the person who sold it to you didn't want to pay the high amount of money charged to replace the logic board.

    I have a similar thread, and it was recommended I contact the person who sold it to me, but that is not a feasible option for me. What about your case? Did you pay a lot less for this Macbook, or a "typical" price?

    I tried AHT, but pressing D just got me to a grey screen for a minute, then it showed up the Apple logo, and logged in normally.

    Option + D, got me on the online AHT which worked except for my ISP seems to be blocking the specific ports... So I got an error.

    @jeepman69
    I paid a fair price for it. Also, when I was at his home and doing the payment over online banking, the computer went smooth as well.

    OK so i finally succeded running the hardware test.
    I get this error:

    "4HDD/11/40000000:SATA(0,0)"

    To me it looks like a problem with the harddisk, but it's a completely new SSD? And how can that mess the battery up?
