    Hi,

    I have a mid 2010 Macbook. Yesterday whilst streaming video the video started to fade out to white but the audio remained. I had to long press the power switch and reboot but on startup the screen showed the apple symbol after the chime but then froze. This happened about 5-6 times until it booted up properly and I continued to used it for the rest of the evening with no problems.

    I powered my Macbook up today and the same thing happened but instead of the apple showing there was just a mesh of crossed coloured lines all over the screen. This time it has taken about 10 attempts to reboot before I can boot correctly and I have now been using it seemingly with no problems for about 2 hours.

    I have tried to use the hardware test but if I boot and hold 'D' nothing happens, it just boots to the desktop (could this be because I have upgraded from Snow Leopard to Lion?). I have also tried to run the hardware test from the Install disk but can't seem to find the correct menu.

    I called a local engineer who told me that without doing diagnostics it seems as though the video card is on the way out and would need to be replaced. He has just emailed me a quote for the card only which comes to ₤420 + VAT (In which he also described the card as a Logic card?) which is quite worrying as I am no longer under warranty.

    Does this seem a reasonable diagnosis with the little information that I have provided and is it really that expensive to get fixed? If anyone can offer me any help it would be very much appreciated.

    I posted about this months ago! No one said anything. :(

    This happens all the time on the 2010 machines. In my experience, on 2010 15.4" Macbook Pro(MC371, etc), the fans don't kick in over about 1000 RPM until the laptop has been on for ten minutes. If you use the laptop heavily before ten minutes, the CPU/GPU temps go through the roof and it fries them.

    The 15.4" line of laptops have been a sore spot at Apple for a while now. 2006 A1150/A1211 Macbook Pro had its fair share of issues. The 2007/2008 one uses a rather heavy screen that breaks the frame, and has the GPU issue. The 2008/2009 Macbook Pro have the frame breaking issue. I thought upon dismantling the 2010 machine that it would be a beautiful, bug free masterpiece! No such luck.

    Used, the video chip for that machine is worth under $100. Replacing an entire logic board because of one faulty component is usually the last resort of a company that lacks the experience to repair the board at the component level, which is really all you need if the rest of the laptop functions fine. There are shops performing this repair all over the U.S. ranging from $75 to $270.

    We frequently perform these repairs and tell people to either wait ten minutes before doing something CPU/GPU intensive, work only in the wintertime, or buy a Lenovo. Keep in mind even if you do get the repair work done that if you do not change your usage habits to match this machine's issues, it will likely happen again and again.

    It sounds like your MacBook is suffering from the well known nvidia 9400 GPU fault (just google those last 4 words and you'll see what I mean). This particular GPU was fitted to a wide range of laptops and is well known to overheat which causes the GPU to seperate from the main board (apple call it a logic board).

    The cheapest way to fix this properly is to get the GPU reballed by a company that specialises in this.

    You mention you were quoted a price in UK £s so somewhere like this will do the job adequately and provide a 3 months warranty on the repair: http://www.ebay.co.uk/itm/Apple-Macbook-Pro-A1212-A1151-A1211-A1150-REPAIR-SERVICE-Nvidia-GPU-LOGIC-BOARD-/180906412743?pt=UK_Computing_Laptops_EH&hash=item2a1edccac7#ht_2834wt_922

    Hope this info helps!

    If his machine was truly from 2010 this is not the NVIDIA 9400 GPU he has. He actually has a different motherboard with a different chipset completely. It is not under recall yet, although it will likely be once enough people complain. :)

    Good point, for some reason I had it in my head that mid 2010 models had the 9400 chipset.

    @ OP, is it definitely a mid 2010 (MC516*/A) or could it be a late 2009 (MC207*/A)?
