Reader Ted Gresham’s older MacBook Pro is misbehaving. He writes:
“I have a 2010 15in MacBook Pro. I pulled out the DVD drive that I never used and installed an SSD drive. Lately, the MacBook has been crashing – displaying a black screen and then a message that I have to restart. Did installing the SSD drive break my Mac?”
No. I’ve seen reports of this happening with this particular model – with and without an SSD installed. The consensus is that the computer’s NVIDIA GeForce GT 330M graphics card is to blame. This MacBook has the ability to switch from high-performance graphics to on-board graphics and switching from one to the other can cause these black screens and kernel panics.
There are a couple of workarounds you can try. The first is to launch System Preferences, choose Energy Saver and disable the Automatic Graphics Switching option. This causes the MacBook to always run high-performance graphics, which will affect battery life.
You could also try the free gfxCardStatus application. This places a menu in the Mac’s menu bar that allows you to choose one graphics card or the other.
This issue has been acknowledged by Apple in its MacBook Pro (15in Mid 2010): Intermittent black screen or loss of video KnowledgeBase article. For your purposes the most important passage of that article reads: “Apple will service affected 15in MacBook Pro computers free of charge until three years from date of purchase.” If it were my laptop, I’d take it in to your local Apple Store or Apple Authorised Dealer (or, if you don’t have a local Apple Store, contact Apple’s support and service folks at 1-800-275-2273 in the US. The equivalent Australian number is 61 1-300-321-456).
The problem doesn’t affect all mid-2010 15in MacBook Pros. If you’re not Ted and haven’t seen this problem with your MacBook Pro then your laptop isn’t affected.
