Screen freezes & questions on replacing the Logic Board
Hi people!
Short version story
I decided to change the Logic Board of my Macbook Pro mid 2012. I have found one in this place.
https://www.powerbookmedic.com/MacBook-P...
- Any special and practical considerations to have on changing a Macbook Pro Logic Board? Thermal paste?
- Would i have any trouble with a new logic board of 2012 and my Apple ID? some friend told me that could be an issue
- For your experience, is Powerbook Medic a trustable Mac Parts seller? look all right but does not hurt to ask ;-)
Thanks for your kind help!

Long version story ;-)
My Macbook screen freezes. Sometimes minutes in use sometimes after an hour. I did ask this question a while in this forum and for a while it was working. I deleted almost every App, format the Disk, install antivirus and used Onyx to scan the system.
Now i send it to a repair service (non Apple) and they tell me it is the graphic chip. Not sure it is 100% right or they just say it as may be is a common diagnostic. The repair service charge quite a lot for repairing the logic board and not guarantee is given the repair will be successful.

Hi people!
Thanks again for all your help with this issue.
I received the hard data cable and did change it yesterday. It is working without freezing now, so that could have been one of the main issues.
However i did notice since i changed the optical drive for a second hard drive that the metal texture of the bay was imprinted on the interior of the bottom case. That means that when flexing they did eventually came in contact. I guess metal with metal could be a source of freezing too, right? Just to be sure, could i put some insulating tape on it? Would any 3M electrical tape would work for that or is a special tape? I guess is just similar to the thinner black tape the bottom case has, right?
Thanks again and cheers

@uzapucax I've been dealing with powerbookmedic for about 10 years off and on and never had any issues. This model had issues with the Hard drive/IR cable. Replace it with a newer cable and see if that resolves it. If not go with the logic board.

Did you notice if it freezes when you move it around ?

@oldturkey03 Thanks for the good advice! I will try to replace that before the logic board.

@arbaman now that you say it that is an issue. Sometimes the screen will freeze when not moving but almost all of the time IS when i move it.

@uzapucax - Happy to hear the cable was your issue! Its a very common problem more so when people upgrade to SSD's as the original cable where not well made to support the higher data rate a SSD can push.
As to your optical drive adapter/drive making contact to the bottom cover. Spinning HDD's drives come in different heights! So a overly tall drive can touch! So you do need to be careful not to put in too tall a drive.
I would recommend going with an SSD! These tend to be much lower in height, and frankly they are better for laptops unlike HDD's which tend to fail from a bang or drop and consume more power shorting its battery run time.
Don't forget to accept the answer - Thanks!
