    I would ask to talk with the store manager and demand that they give you a new computer if your warranty hasn't run out.

     

      If that doesn't work, I would at least tell the better business bureau   http://www.bbb.org/

    Apple has released an EFI update to address this issue.

     

    See: http://support.apple.com/kb/DL1502 to download or run software update on your computer.

    "This update is recommended for MacBook Pro (15-inch, late 2008) models. The update resolves a graphics issue that may cause the internal display to flicker."

    I can't belive it ! Just in time for 100th page! Let's try!

    LMAO! Three years and thousands of ignored post.... I can't wait to try this and see if it fixes the most annoying and embarassing defect on the MBP.

    Doesn't sound promising.  According to Apple, this update is specific to 2008 15" models.  I had the flickering problem on a 17" 2010 model.

    Just let us know after a few days if it seems to fix the problem.  No need for hundreds of "I installed it too!" posts.  Thanks.

     

    We already know that some affected models aren't going to be fixed by this, because it won't install.

    Great. Let us know if it blinks after you change your setting to better battery mode.

    It seems that with my 5,1 15" it works... I don't know how but it seems to work... I installed it and switched on 9400go, and in this hour of use I have not seen any flickering. Before I was always on 9600 because my mbp used to flicker 2-3 times per second... so I think this patch is successfull. Yes... after 3 years they have done something working OMG. And a software fix seems to fix an hardware bug... Something is not clear.

    I bet they disabled something in the video card that caused the flickering. It would make little sense otherwise. Glad I exchanged mine for a 2011 one in time, but at least they did something.. 2 months ago they treated me as an alien with a rare problem..  as if I were the only one..

    Just installed "MacBook Pro EFI Firmware Update 2.8" and no flicker with NVIDIA GeForce 9400 so far.

     

    I can not express how unbelieveble it is that Apple took 39 months to fix this issue. I don't know if it's more amazing that they took so long, or that they actually fixed it.

    Anyone Apple Hardware Test after the update to make sure that the update does not cause hardware issues?
