Hi, I have a 5,1 MBP bought in March 2009. I haven't used the 9600 for about 6 months, but now when I try to activate it under Energy Saver, and go through the whole logout/login process it doesn't enable. I still end up with the 9400. I've ran the hardware test and it only lists the 9400. I've reset the PRAM, no effect. System Profiler has no mention of the 9600. I also tried installing Windows to see if the 9600 would show up there, but I get a blank screen when booting the XP CD. I get the same blank screen when trying a Linux CD. Is this perhaps because the MBP is trying to use the 9600 but it's borked and not displaying anything? I've had Windows running under Bootcamp on this machine in the past without issue. Note that I did use the 9600 for a while last year, and had no issues with it at the time. Anyone had any similar experiences to this? I'm wondering if the whole broken 8600 issue extended itself into the 9600s as well... The Inquirer had some details on this, but I haven't seen any widespread issues reported on the net. I don't have Applecare for this machine, so it's now out of warranty. If this is a manufacturing defect, I'd hope that Apple would fix it regardless, but maybe that's just me being optimistic... Any comments?
