REPAIR SERVICE - Graphics Card Hardware Bypass for MacBook Pro 2011 Dual GPU Models
Stock Status: Available.

This is a repair service that is performed on our premises. Once booked you will need to either bring or send your machine into us, or you can have us send our courier to collect it - see here. Once complete you can collect the machine from us, or we can ship it back to you for our standard courier delivery charge (applied during the checkout process).

What is this service for?

There are moderately common issues with the graphics cards in some 2011 revision MacBook Pros - effected models are those which have a dual GPU setup with both and an integrated and dedicated graphics card (so all the 2011 15in and 17in models, but none of the 13in). The dedicated card develops a fault, which can sometimes be worked around by forcing the use of the integrated GPU only, but often ends up with a completely non-functional machine.

What does this service do?

It completely bypasses the GMUX chip, which is responsible for switching to the faulty dedicated graphics card. In effect forcing the machine to use the integrated card at all times. While this has some drawbacks (see below), it permanently resolves the failure caused by the faulty dedicated graphics card.

What does this service involve?

The technique was developeded by user dosdude1 on the macrumors.com forum (see thread). It involves soldering microwires to the GMUX chip so that the dedicated Nvidia GPU is permanently disabled. Correctly carried out this repair is permanent, cannot be overwritten with PRAM/NVRAM resets (the problem with pure software "fixes") and is a good tested solution.

Upsides

  • Permanent hardware fix.
  • Battery life improved.
  • Never worry about software updates or PRAM resets.
  • No software to install or update.

Downsides

  • Native Windows booting (Boot Camp) is not supported. Running a Windows VM (using Parallels or similar) is fine.
  • No brightness control. The GMUX chip is responsible for brightness on the machine so bypassing the chip will result in the machine's brightness being 100% all the time - you can install third party software to adjust the brightness.
  • No external video output (the Thunderbolt port does work, but not for video output).
  • Time consuming to do (so fairly expensive).
  • Loss of the dedicated graphics chip - 3D graphics performance will be much poorer, and intensive GPU accelerated tasks, such as rendering, will be considerably slower due to the absence of the chip.

We have performed this procedure on a number of machines with completely dead GPUs and machines which have failed for reflow and even machines with burnt and deformed GPUs. All work flawlessly.
