MBP Worst After Logicboard Replacement

    I have a late-2008 Unibody MBP. My trackpad wasn't working well and I was getting a blue screen now and then. Took it to the Apple Store and they replaced the trackpad and logic board. Now the computer runs super slow after about an hour or two. I never had a problem having FCP, Photoshop and Firefox all opened at the same time. Now I get a lot of spinning rainbow wheels when I do that.

    Any suggestions on the culprit? Is there some sort of disconnect between the system files on my hard drive and the new logic board? Would a reformat remedy this (I would really prefer to avoid this route). Or could I have another faulty board? Thanks

    It is an hour away. Kind of want to try to trouble shoot it on the forums and take it to Apple as a last resort. :/

    not worth of troubleshooting yourself with your MBP…take it to Apple store..better than void your warranty if you do something wrong.

    did they explain why the board was replaced in the first place?
    are there any firmware or software updates after getting the mbp back?

    The only thing I would suggest is backing up your HDD time machine or otherwise, and running DiskWarrior on it to see if they could have messed up the HDD somehow. they may swap out the board and HDD if its an Apple branded one for a new one.

    An hour away! You should be glad it's only an hour away; that's close compared to many other locations. Take it to an Apple Store ASAP.

    They tried to explain that I was getting the blue screen because the logic was confused about whether one of the ports on the computer was being used or not. They did not explain why the trackpad was behaving the way it did.

    This could be a flawed theory on my part but I was thinking perhaps there is some sort of disagreement between the system files on my hard drive and the new logic board, basically, the new logic board and my old hard drive are not a perfect match. If that is the case, then a complete reformat should do the trick. Just don't really want to endeavor on that if I'm barking up the wrong tree.

    The hard drive that is in there now is an Apple branded one.

    I am also going through the same issue. My MBP was a part of the failed nvidia chipsets. Apple replaced the Logicboard, keyboard, wlan adapter (only cause they broke the original), and all 4 of the little round pads on the bottom.
    Since the replacement my wife and I noticed that its a bit slower, especially while on websites that have flash.
    I upgraded/increased the ram, and installed a 7200rpm HD. Reinstalled the OS. Its still acting weird. Its way out of warranty, the original repair was back in december 2010.
    Ill call em and see what they will offer.

    Planet earth.
    Get your hands on Onyx and CleanMyMac and run some scans and diagnostics thoroughly along with Disk Utilities verifications/disk permissions.

    Reset the PRAM and the SMC. If that doesnt help, REINSTALL the OS. If that doesnt help, then you've definitely got a botched logic board.

    check and see though too if theres any application running on startup that messes up stuff. I had some issues with RightZoom giving me problems.

    what you could also do, is partition your hard drive and do a quick install of OS X on the new partition and see how it runs. This would effectively save you from backing up/losing settings and files. It'd just be a test.

    i have always said that once apple goes in to make a major change, the machine is never the same.

    after apple replaced my top case on my umbp 17" i had so many problems...eventually leading to them forgetting to reconnect my backlit keyboard and dvd drive and they replaced my entire machine (this is not the reason they replaced it, but was the final straw)
