My Macbook Pro 15" i7 of early 2011 seems to have a major problem related to the logic board.
in a nutshell, in case you don't have time to read the details:
The computer stopped starting up after quite a few restarts, AHT, PRAM reset, safe boots, new RAM and new SSD. This all happened withing 3 days.
Apple service guys will look at it tomorrow, but they already said it's most likely logic board failure and will need replacement.
the long story:
symptoms I faced along the way:
- less than two weeks ago, screen started freezing forcing me to force-shut down.
- started repeating within hours, occasionally giving Kernel Panic message.
- within a day, frozen screens had several varieties which would either come after a few minutes of working or at startup: blue screen with vertical bars of different shade blue, or same with yellow tones, or the last seen screen with a couple inches of the of the right side of screen having shifted to the left side with a thick black bar in between the two (i could still move the mouse for a while but not able to click).
- started also having sessions where the computer would not start up at all (blue screen or gray screen with wheel turning)
- in between these steps I ran the computer on safe mode mostly successfully, did Apple Hardware Test 3 times with nothing wrong diagnosed (took 18 mins each), I did PRAM reset a few times too
- i tested these with different peripherals and power cable attached and not attached (normally i have a USB external and one or rarely two firewire drives attached for my video and photo work).
I realized that the computer would still be working after the freeze too. I use the MBPro to share internet for my iPhone and while it was frozen I still had internet.
I was following the suggestions on these forums to diagnose the problem.
Some suggested that it could be the RAM.
Coincidentally, the new 16 GB RAM that i had ordered came with the 246GB SSD just then.
As warranty ended already some months ago, I did the replacement with my dad who is an electrician and would know where to touch where not to.
The computer came back to life, super fast with the new SSD. I installed Mac OS X on it, set up the older HDD which I placed in place of the old DVD drive and started moving files around to configure my stysem.
after several hours the screen freezing came back again.
then after repeating the above steps of AHT (which took 2 hours), PRAM etc, it stopped starting up. It won't start anymore. Freezes in the early blue screen.
Just before new year's, I took it to Apple Service in a local store. They said they will have to look at it thoroughly after the 3rd (tomorrow). But the guy said the symptoms which I wrote above pretty much tell already that the logic board is dead.
Can it die in a slow manner like this?
It will cost me at least 750$ and I am not even sure if shipment and labor is included in this (I live in Cyprus). This is a very expensive price to pay for a relatively new machine for which I already paid over $2000 when I bought it 18 months ago.
I read Apple has a tendency to call all such symptoms a 'dead logic board' and just rip people off unfairly. I am aware this was mostly for 2007 and 2008 models but I worry they would still do it. I just spent my savings for the SSD and new RAM. So this is a major bummer.
What would you all suggest for me to try? How should I talk to the Apple Service guys?
is it better to just sell this 'as is' and try to get a new or properly working pre-owned one?
