Black Screen
Hi guys, my problem carries on. I will take MacBook Pro to Service Center next week to have it cleaned, in case this is the problem (overheating). I have also received this reply from a very knowledgeable person on Apple:
The black screen issue is pretty widespread. If I remember correctly, it usually happens when you're using the discrete GPU, so if you can stay on integrated as much as possible, that will probably help your cause.
gfxCardStatus' three modes are like this:
- Integrated Only forces the use of the integrated GPU, which is less powerful, and uses less battery power.
- Discrete Only forces the use of the discrete GPU, which is more powerful, and uses more battery power.
- Dynamic Switching is the built-in automatic graphics switching feature that OS X comes with. OS X "intelligently" switches between your two GPUs depending on what kind of applications you're running.
I have lots of friends at Apple (worked there in the past, and working there again this summer), and they're working diligently on the issue. Issues like this are extremely difficult to reproduce and can be difficult to fix, because it's a pretty low-level, complicated thing. Make sure you've got all of the latest updates from Software Update (especially firmware updates).
I will advise on further updates. Peter
