and that no repair in the world will work for me, but that I actually have to trash my beloved 17" MacBook Pro and get a new smaller MacBook Pro which I can not possibly afford right now, especially after spending 500€ to replace the logic board just a month ago? So what am I looking at here? Is this apple's way of telling me, I can not own a MacBook Pro for more than 3 years. and I was actually working on a fairly big photoshop file, but still my macbook wasn't even hot on the outside yet, and it actually heats up fast. Only 3 applications running were: Finder, little snitch, photoshop cs6. Then my screen split somewhat around the middle and everything that was supposed to be left was right, everything that was right was left, I could literally move my mouse to the edge of the right side of my screen and it would continue on the left side. 8 hours ago, I started getting the same error as before, my screen started flickering, even though I hadn't been working on the macbook for more than 2 hours. If the computer restarts when you press the SYS_RST switch but not from a cold start, the power supply may need to be replaced.So exactly a month later, as you might recall I got a new logic board into my old MacBook Pro. If the computer boots after you press the SYS_RST switch, try shutting the computer off and restarting by pressing the front power button.To press the switch, use the nylon probe tool (Apple part number 922-5065). With the computer powered up, press the SYS_RST switch located in the upper right-hand corner of the logic board.This switch can be used to determine if a computer that won't consistently boot from a cold start has power supply issues.
