MacBook Pro 2011, I replaced the logic board but can't get it to work

Hello

I have a Macbook Pro from early 2011 and I had problems with the video, I took it to a technician to reball it and it supposedly worked, at the same time it failed again and this time they told me they had changed the video chip.

In the end, it failed again and when I took it to repair it again it did not work again.

I finally bought a used logic board in china and was able to successfully install it as a replacement for the deceased one.

But I have the following problems:

1 The battery or battery charger does not work so the fans run at full speed.

2 I was able to get it to boot but it does not recognize the SSD.

3 I put the original hard disk (unfortunately it had been used for a windows pc) and tried to install different versions of OS

- Yosemite USB installation (failure to finish preloading the USB, the computer restarts and the installation begins again)

- Installation via USB of El Capitan (failure to finish preloading the USB similar to Yosemite) but then I was able to install it with "Clover" and the installable image of El Capitan. The installation was successful but when the mac tries to start it reboots before finishing the progress bar with the apple at the start. This installation only works failsafe and I cannot start the diagnostic mode (D, cmd + D, option + D) nor the recovery mode (R, command + R)

- Recovery using time machine, since I have a copy of High Sierra, I recovered the complete installation but the behavior is the same. Fails to start unless in safe mode.

- Currently installing a minor version (mountain Lion) install the first stage, restart and start installing the second stage. it always restarts after 30% and starts again.

4 In the El Capitan version I uninstalled the drivers for the dedicated video card, hoping that was the problem, but I never got it to boot normally.

I also did all the possible updates and only the installation of "MacBook Pro EFI Firmware Update 2.7" fails because when the Mac restarts to do the update, it restarts again and again and only continues in safe mode. when I look for if something needs to be updated, "MacBook Pro EFI Firmware Update 2.7" reappears

Please if you can tell me what steps to follow or some guide would be saving me.

I am in Argentina and the prices to take this equipment to an official service are exorbitant and unreliable.

Update (08/31/2021)

Hi @danj , you really blew my mind!

First of all thanks for your help and advice, in my many searches I found many of your contributions and they were always very helpful.

I read quite a bit about it and to try and rule out that this was the problem and did the following:

Using my other computer (macbook pro early 2013) and internet recovery I installed mountain lion on a 16Gb pendrive. I put it in the macbook pro 2011 and by pressing option I told it to boot from it.

To my surprise and for the first time it managed to start!

I even managed to install the update "EFI Firmware Update 2.7" ...

My joy ceased when it rebooted for no reason while trying to install the Safari update. (started downloading update and failed)

The mac rebooted again and while loading the OS it rebooted again! This behavior persists as long as a reboot failure occurs and I think I manage to stop this reboot cycle when I hold the power button and turn on again while pressing the option key to choose usb as startup.

As you had indicated to me that the cable could be the cause of the failure. Disconnect the hard drive cable from the logic board. I started again and it rebooted again :( again trying to update Safari.

Just in case, also disconnect the cable from the optical drive.

With both units disconnected it continues to fail.

Currently, it only has a 16 Gb USB as a hard drive.

Since I couldn't update Safari, I downloaded Chrome and managed to install it.

But as soon as I want to start Chrome and the icon starts jumping on the dock while loading, it restarts again ...

Here's my suspicion: Could this be a matter of memory? Currently, it has two 4Gb memories and before doing all these tests I had changed them for two 2Gb and it also failed.

Update (09/02/2021)

Here it is the report I got booting into safe mode

Hi there!

Once again @danj and @mayer thank you very much!

I have great news!

It was just a matter of putting in the battery and the computer just worked perfectly!

I was able to install High Sierra without any problem.

All programs work fine, only the battery drains extremely fast so I am going to contact the seller tomorrow to ask if there are any charging methods that I am not doing correctly.

In case that GPU starts acting up again, try installing gfxcardstatus

’ve saved about twenty 2011 15” MBP using this gem, it’s also free ;-)

To turn off the dual graphics capability of the GPU, install gfxCardStatus for Mac

Download  https://gfx.io

This will disable GPU switching and force the MacBook Pro to use the higher powered discrete graphics card rather than the integrated GPU.

  1. Go to the  Apple menu and choose “System Preferences” and then go to “Energy” control panel
  2. Uncheck the box next to “Automatic graphics switching”
  3. Note the text which states this may decrease battery life on the MacBook Pro “When automatic switching is disabled, your computer will always use high-performance graphics. This may decrease battery life.” – if you are not OK with that do not disable this option
  4. Close out of System Preferences
  5. You can always return to the Energy preference panel to re-enable the GPU switching feature if desired.
  6. For MacBook Pro users who want to manually control their GPU use, you can use a third party tool like GFXCardStatus which has been around for quite some time and still works on most modern MacBook Pro models as well.
  7. https://gfx.io/switching.html

Hello @mayer I will follow all of this and will let you know!

Hello @mayer

I messed up a bit with the comments and responded to @danj instead of you.

I booted again with the hard disk in safe mode and managed to install GFXCardStatus, configure it to use only the "discrete" board only. But when trying to start, it failed as usual.

I'm going to add a report that I saw when I finished logging into safe mode again as an edit of my question. Could you take a look?

из

Hello again @danj

Unfortunately, there was no luck with gfxCardStatus, I could not install it on my pendrive with mountain lion because they no longer support that OS.

I connected the hard disk again and with "El Capitan" I successfully downloaded the program but I can't change to "Integrated only" because being in safe mode the message that gfxCardStatus shows me is the following: "You can't switch to integrated only while the following item is running: External Display "

Apparently, it considers that I am using an extra screen or something similar, which is not the case.

Any ideas or direction in which to point my cannons?

из

@pumita70 - Did you check my update above?

из

Hello again @danj ! The one who talks about throwing in the towel? Yes, I saw it.

It happens that due to the costs of a logic board and that this is the one that I could buy and above all that I cannot return it because the shipping costs plus the taxes for what I paid would end up losing even more money, it is that I want to exhaust until the last possibility.

It sounds like you’re hitting a known issue when running a newer SATA III (6.0 Gb/s) drive in this series as the original HDD Apple used was a SATA II (3.0 Gb/s). What you’re hitting is the limitation of the original HD SATA cable. Apple didn’t design it well enough to support the faster data flows of a SSD drive!

OK what to do? Time to replace the cable! This is the needed part MacBook Pro 15" Unibody (Mid 2012) Hard Drive Cable and yes! Its the 2012 models cable which is the better cable. Make sue you don’t crease the cable as that will damage it, you want to use an old BIC pen ink straw to help form the radius bends when the cable needs to bend. Here’s the needed guide to put it in MacBook Pro 15" Unibody Early 2011 Hard Drive/IR Sensor Cable Replacement

Lastly, you’ll also want to place a strip of electricians tape on the upper case to protect the cable from rubbing Your Hard Drive Cable Is A Ticking Time Bomb to be doubly safe.

@pumita70 - I think its time to throw in the towel ;-{

I think the repair shop really messed up your logic board. At this point I would look for a 2012 logic board as that will get you a better discreet GPU.

For reference I'm using right now such a converted 2011 system! The logic board is a direct replacement with one small change needed carefully filing the edge of the LVDS cable tang as the socket is a little wider.

After writing this I plan to test the operation with a single memory bank used and in each slot, that is, I will test a SODIMM in each slot to rule out that one or the other fails.

Finally, there is a way to know the reasons for the failures in the console? And if so, could you tell me where and what to look for? Well, for me the amount of information that is shown there is very large and I honestly understand very little.

If there is something that you think I have to do or you need specific information, please do not hesitate to ask me.

Totally grateful to you.

@pumita70 - Did you replace the cable? The drive likely needs to be reformatted as its messed up from all of the failed writes.

Beyond that, you maybe hitting the second failure issue of this series the discreet GPU! Follow @mayer instructions, but you first need to stabilize your drive setup first!

Hello @danj I didn't replace it yet since I must order it from the capital city.

That's why I where testing with the USB and with the cable disconnected from the logic board.

BTW the sodimm tests didn't produce any good results.
