Booting Problems finishing in frozen white screen - Logic Board?

Good Day,

I have a problem with my Early 2011 MacBook Pro 15" all was fine, after suddenly I started getting distortions and lines on the display.

Soon after it wouldn't start anymore. When booting the Apple Logo and the progress bar are now green i/o black... and halfway through it stops and the screen switches to white and remains.

I've reset the NVRAM and the SMC, even opened and disconnected the battery for half an hour but no change.

I also tried Internet recovery by booting with option/cmd/R - I can choose the network, enter the password and the globe starts turning and the progress bar starts (all in green) it finishes the download. Than the Apple logo and progress bar of the boot sequence comes again (still green, and half way through the screen goes white and thats it...GRRRRRRR

Anyone able to help point me in the right direction? Dont know what else to try...

Specs:

MacBook Pro 15" Early 2011 2.0 Ghz i7 (Model A1286)

  • 1TB SSD Samsung EVO 850

This is the classical GPU (graphics card issue) 2011 edition. This problem was acknowledged by Apple and they've had a recall which ended in December 2016.

Not a lot to do now even if you find a repair shop who does graphics card replacement/reballing the issue still remains because is a design flaw of this machine...

Hmmmm I thought the GPU issue effected the Radeon Graphikcards but not the Intel on board.

Nevertheless, is there a supplier for a Logicboard somewhere with reasonable prices ? Maybe does a different Logicboard fit ? Different year ? Which Models are affected of this design fault ?

am prepared to change it myself if i have to, if i find one for a reasonable price.

Cheers

Chris

Dual graphics processors:

- An AMD Radeon HD 6490M with 256 MB of dedicated GDDR5 memory

- And an Intel HD Graphics 3000 graphics processor that shares 384 MB of memory with the system within the CPU chip

@femo You have more details on https://www.apple.com/support/macbookpro... about the affected models.

Ebay is a good source of logicboards the problem is that the compatible logicboards for your Macbook are susceptible to the same fail like yours.

Better go with a newer model for more peace of mind.

thanks a lot @soros but i just spent 700 bucks for the upgrade.....

I think i take my chance :-D

But thanks for the help !

@soros is there a way to turn the second GPU off with software?

@mayer using gfxCardStatus, a little software that will disable the discrete GPU on startup, works very well. If you can still start the laptop, it's easy to install (so do it as soon as the graphics problems start to appear!). If you can't start it, there is also a method here https://forums.macrumors.com/threads/201...

Anything regarding replacing the GPU (even with the so-called 'new' version) will only be temporary, it will fail again (I tried), so better plan to use gfxcardstatus on the long term.

However, I just had the SMC chip replaced on mine (it failed at the same time as the GPU did), and the cost - 300€ - was the same no matter what they replaced. As soon as the GPU fail again (between 6 months to 2 years from now), I will use gfxcardstatus to switch - and I can install it now.
