    I've had a logic board replaced in my 6.2 mba in an apple store due to hw failure (it showed no signs of life). but now it keeps on crashing every half an hour, i've tried to reset both smc and nvram and also updated the efi. Any ideas what the problem might be? should i take it back to the apple store? Thx for reply! :)

    here's one of the logs from console:

    Yes you should take it back. The computer should work fine after the repair.

    update: is there a way to tell (from the logs) whether its really a hw issue? ive been experimenting and it did not crash while in safe mode or recovery mode but i cant tell for sure as it doesmt crash in regular intervals. the thing is i dont want to be another week without my laptop if theres a way of solving the issue myself; if its just a software thing

    Do newer machines still have tech tools or anything like that? Apple HW check?
    Anyway, you just got it repaired. Take it back and don't waste your own time but call them first and maybe they will help you. Strike that, they should help you considering it was just replaced.

    i need it for work i make websites... :( my guess is that its just a loose connector on the mother board however i dont wanna mess with the warranty so im not going in. im gonna give reinstall a try to see if its really hw failure. thank you guys for opinions. and im gonna give the apple hw check a try once it finishes the instalation

    Tough choice. You can either live with a Mac that crashes every half hour. Or you can take it to the store and get it fixed. Yes, that's a tough choice. :mad:

    The problem is quite simply that someone messed up when they replaced the logic board. There's no point trying to work around that problem, you paid for a proper repair, so that's what you should get.

    And why would you try to reinstall your software? Do you think they sneakily replaced the software on your Mac with a different version that creates crashes while they replaced the motherboard? That's quite unlikely, isn't it?

    A loose connection isn't going to cause crashes. The RAM and CPU are soldered in to the board and there isn't really anything else that is likely causing kernel panics. You need to take the laptop in and have it repaired, it sounds like the replacement logic board is bad.
