The description of logic board: The computer adopts a new generation of highperformance logic circuit, and with better heat dissipation effect. If you are looking for logic board, the brand of sheli is your good choice. Runs just fine.A1278 Motherboard For Macbook Pro 13" A1278 Logic Board With I5 2.5ghz/i7 2.9ghz 820-3115-b 2008 2009 2010 2011 2012 Md101 Md102 - Laptop Lcd Screen - AliExpress The basic info of logic board: The application is laptop. I now have a perfectly-functioning MacBook Pro late 2011 15-in model with Discrete Graphics disabled. I have made the Arch Linux bootable CD on another Mac, and tried this approach. I used the second from MacRumors as it seemed easier. This page and scroll down past the list to the blog: In particular, the use of ArchLinux bootable CD to gain access to and re-write the EFI on the drive, and permanently disable the discrete graphics chip. In addition, Steve Schow writes that he has abandoned further development - because there are better solutions available.
app for direct download - you do not have to compile anything.Īlso note that if your Mac does not run long enough to allow gfxcardstatus to be added, this is not really practical. There is a fork off the main build by steveschow available that seems to fix that problem for current versions of MacOS such as ElCapitan and Sierra. There is an acknowledged bug in the current version of Cody Kreiger's Open-Source gfxcardstatus, and the developer has confessed he does not have time to fix it right now. The alternative is replacing the logic board, which is not cost effective on a machine that old, unless gfx does not resolve the issue and you really want to keep this MBP. This may allow your MBP to run normally, although it will have reduced graphics performance when permforming demanding graphics tasks. It will allow your MBP to run on integrated graphics only, bypassing the discrete GPU which has the issues.
Install gfxCardStatus ( ) and set it to "i" (integrated graphics only). You lose the ability to attach an external display, and certain filtering operations will be noticeably slower. They disable the Discrete graphics processor and allow the machine to continue to work on just the Integrated graphics processor.
