what is the graphics card in macbook pro

This can end up with a dead battery while on an airplane pretty quickly. The problem is, I often forget which one I am running. It has been a painful process but after the ram (16gb) and drive (SSD) hacks I am still using it and I can say I got the best out it even if I know its lifespan is limited one more year.There is a big difference in both performance and power consumption between the two video cards in a MacBook Pro. So don't be surprised if it happened to you recently because if it didn't happen earlier you've been very lucky!

It happened again more recently in December and they replace it again telling me the scheme was active till the end of 2016. Unfortunately the GC is welded to the mother board so they replaced the whole logic board for free as it was part of a scheme related to a wrong batch of 2011 MBP. The diagnostic test I run was positive so despite the result I booked an appointment to the genius bar and they confirmed the graphic card was gone. I have done all sort of tests and reboots and I managed to restart the machine in verbose mode after many attempts (google the instructions, I cannot remember what I did precisely) even when the screen was just blue/grey or whatever colour just to save the latest files. So what could it be? Is it software or hardware based?Īll the problems you guys mentioned above are related to a faulty graphic card. The issues mentioned above started when I was using the monitor, but I had the same issues when I disconnected any external devices or peripherals later on. It's a fairly heavy screen running at full resolution of 2560x1440 but that's completely supported by Apple. I recently started using an external monitor directly through the mDP. I used the Apple Hardware Test to identify what might be the problem but with the normal as the advanced test results say there no issue with the hardware.

Since then I tried to reboot but every time it cuts of the boot and the screen goes completely blank. Blue and red line in overlay.Īfter a while I could use my MBP again, but yesterday it stopped working completely. I'm using a MacBook Pro 15' late 2011 running 10.10.5 and in all of a sudden my screen is acting weird. I think my graphics card is failing but I'm not 100% sure.
