Hi I'm having a frustrating time with my mack book this afternoon. My partner was using it to study and it suddenly turned itself off, when trying to tern it back on the start up chime would sound, the apple logo would display and then it just dies. I've tried accessing the recovery drive, but it does the same thing, I've tried using command+S but it show for 3-4 seconds and then dies. I tried accessing the bootcamp partition and again as soon as it shows windows is starting it dies again. So i tried pulling the drive out and connecting it to my pc, naturally I can't do much with the HFS+ partitions but I ran chkdsk on the windows partition and it shows no errors. I guess I should mention that the drive itself is a Sandisk extreme 2 SSD. So now I'm re-downloading an image for mavericks hoping that i can get it to boot, I'm not to worried as everything is backed up to my timecapsule, itunes match and icloud and the drive itself has a 5 year warranty, and most web searches only seem to talk about faulty drives, but would anyone have any idea if it could be something else? It's a 17inch macbook pro late 2011 model. Any advice would be great.
