Q: 2011 MacBook Pro and Discrete Graphics Card

Again, I have searched this forum and found no-one who has said his work is as he states.

The fact that he uses pictures to prove his wrok here and on his site makes me nervous to say the least.

I would like to hear from someone who actually used his services.

Why do you think he/she is posting on here, if not to drum up work?

Whether he/she is good or not, I'm much rather use someone who uses leaded solder.

somwhere around page 360-370- some have used his services...have been impressed so far...the replies to his services where also deleted by the moderators, as appearently it was not allowed...but so far he got no returns yet as stated so far in the threads. He actually fixes the problem

as for leaded/unleaded, i prefer leaded, wider margin, and more "elasticity" from the solder so in varying temperatures holds better....i think the problems with the GPU/CPU has to do with the lead-less solder

Same thing here as regard of reballing or wait for Apple...my business needs to continue, so reballing it is....I had it however checked by Apple repair service with verification that it was indeed the GPU, for later call backs to fix it properly...it's clear that replacing the LB is NOT a helpfull option

PS3 SPECIALIST did wwork for me on a 2011 Macbook Pro and he was quick and so far (several days) the machine is working top rate.

Yes, we pay Apple premiums for all their products and as a life-long 30+ year supporter of Apple, I think their hardware quality/design started sinking in 2007 or so.  I've been the unfortunate user of two other recalled MacBook Pro units.

This is my experience too. I'm certain something changed in Apple's manufacturing processes around that time.

All our macbooks bought after 2007 have failed in one way or another (logic board, screen, super disk, etc), but the low end white macbooks from 2006 are still working great and are abused by children every day.

I stated in a previous post (Unless Apple have deleted it) that as of 2006, all consumer electronics started using lead FREE solder to comply with the hazardous waste directive!

I'm aware the differences between reflowing and reballig, are you aware on how long  last a tipical reballing work? and the failure rate on reballing works?

Reballing is an lottery ticket, about 3% of the reballing fails with total loss of the logic board, and succeful ones don't last more than 18 months at best (topically 6-9 months).

I'm not Lobbing here about replacing Logic Boards (Except if the replacement is done by Apple), but is obvious here few people lobby on Reballing as our *panacea*, actually I don't suggest anybody to reballing.

Reballing, Reflowing, and any other repair implies total loss on right to receive an proper fix from Apple on an hypothetical and imminent recall.

I agree, i think the problems started when they changed to lead-free solder...

Do you believe that when a repair specialist CLAIMED they did a reball, and didn't just reflow it? (Lots of con men out there!)

I'd suggest that a reball should last a significant time, as that was how the chip was first attached in the factory. Yes there will be variations in the sucess and competency of the technician. But I do not agree that a reball will only last a few months. However, we will have to wait some time for the results of reballing MBP's to reveal themselves...

I'll be having a reball soon (With leaded solder)

Yes and NO, notwithstanding was ruled by law, leadfree solder is far superior, the problem is when an new production line implement some new formulae, sometimes this formulation fails due n factors hard to foresee (as extreme heating/cooling cycles) so maybe the late 2011 MBP used an diferent solder and will never experiment our failures, maybe some rMBP will experiment our failure sooner also, so itś an lottey ticket and very tricky.

The Improper applicatin of thermal paste (too evident), and itś probable melting is another factor, don blame the soldering yet, the soldering issues maybe caused by the thermal paste.

Wrong, lead free solder is not superiour. Yes it is stronger, but that raises its own issues due to brittleness.

Please do some research on the internet before posting opinions that are not backed up by materials science! 

Is there any way to disable discrete GPU and work only with integrated Intel HD?

MBP 15', Late 2011, AMD Radeon HD 6770, OS 10.9.3

Thanks!

Anyone here knows what would happen if the GPU chip was removed? Will the computer still be able to work?

I've read it is possible to deactivate the GPU via Linux, but the compjter has to boot to be able to do that..

Why on earth would you pay to have the chip removed, and not have it refitted? (Reballed)

I guess you could try to do this yourself, but without the proper kit, it's probably suicide for your Logic Board...

The reason for doing this would be to ensure not having to do a new reball on the discrete GPU and use only the integrated GPU. Not that I'm going to do it, just curious if it would work.
