Anyone ever see this? Sorry it's long but please read. I was diligently playing with my 3rd child (Late 2011 MacBook Pro) Wed. evening and the screen went black. I could tell it was back-lit, but black. I forced shutdown and it wouldn't boot back up, just a black, back-lit screen. I reset the PRAM and it went to a gray screen. Since it's a uni-body (I think that's the right term) I wasn't sure I should take off the back and mess with anything. I have an independent Mac repair shop I know and trust so I headed over to their shop before the holiday weekend. He had the same results. He put in a test drive and it still came up gray. He put my hard drive on one of their systems, it loaded each desktop icon one...at...a...time and he ran some test, it looked like a hospital heart monitor with the up and down spikes. He was explaining as it loaded that a lot of tall spikes were bad. Two guesses what I had? That's right, tall spikes out the wazoo! He said my logic board and my hard drive might be going out! WHAT? Two and a half years?!? That's all I get! Unfortunately, since Apple took away warranty work from any shops that aren't Apple stores and he said even though I am out of warranty and don't have AppleCare I might be able to get assistance or a lower rate for repair, but I have to go to an Apple store. So he tested the drive, put in a test drive to test the rest, and tried replacing the cable that runs from the hard drive to the something (logic board, maybe?). I went home to try to copy some files, I knew I could get it started. I booted it resetting the PRAM and then restarted it again. It booted, but was slow and clearly unstable. I tried running Time Machine, crash. I tried connecting my portable drive, crash. I had to share folders on my 7 year old, very slow and very full MacBook and copy one folder at a time (since it's full - it's my redundant back-up) and then transfer it to the portable drive, delete off the MacBook, repeat. It took forever! FOReveerrr! I did open the back again, unplugged the battery and re-seated the RAM and hard-drive again. So as my slow progress trudged along, it seemed to actually be improving. I didn't want to try changing anything, but life is short and it was ticking by. Did I mention I was in day 2 of copying. So, i tried plugging the portable hard drive directly again and it worked. I was, at this point, copying two years of photos. Iphoto export kept failing, not sure if that is due to my MacBook Pro issues or a limitation of iphoto when trying to export 3,704 pics. Once I finally finished copying everything I shutdown and later turned back on and it booted! I plugged in my portable drive and ran Time Machines successfully! When it boots, it brings up the gray screen with the spinny "I'm thinking thing", flashes solid gray for a couple seconds and loads. Now I can't remember if that's normal or not, but it has worked since. Now I am taking it very easy, only use it a little each day, piddle around on the interwebs and FB, and shut down every day. I am going to test it out doing real work tomorrow. I am also taking it back to my guy to run the test with the spikes again to see if the result is different. So no power surge, working off battery when it happened. Never leave it plugged in when I am not at home and use a newer, quality surge protector when it is plugged in. Has anyone ever see this? I'll also update after I try to do some real work and after I visit the repair shop again.
