This is going to be a longish post, but I'd really appreciate people's feedback and advice. So thanks in advance if you read this. I bolded my questions. I've had a Late 2008 15" MacBook Pro 2.53 GHz with the 9600 GT ever since it came out (literally day one). It gave me years of great use. However, after upgrading to 8GB of RAM a few years after owning it I began to experience minor issues. Every month or two upon waking up from sleep the backlight would light up and the fans would turn on but the screen wouldn't. I had to manually power it down and reboot. This is with 8GB Crucial RAM. This wasn't a big deal although it became much more common starting two or so years ago to the point where it happened once or twice every two weeks or so. At one point it was happening everyday, and I got a replacement set. This made it go back to it's regular frequency. What is causing this? Crucial said it's normal with newer operating systems. Starting like 4 years ago, when I switched to the 9600 GT the system would freeze (mouse stops moving and doesn't ever start again) and I'd have to reboot. But I don't experience this with the 9400M. Anything I can do to fix this? I always just assumed it was a defective graphics card. I'd really like to be able to get this working since the 9400M is really showing its age. This past summer, I had major issues. The computer would just freeze up as described above but for the 9400M too. I assumed logic board issues after it persisted for several days. I was planning on waiting for the Mac Pro upgrade and replacing this, but I needed a computer so I got the Mac Mini in my signature and left this in the box in the closet. Fast forward to around Thanksgiving time, and the computer wouldn't even turn on. I put it back in the box since I didn't need it. I decided to tinker with it again last month, and tried taking and the RAM and reseating it. BOOM! It turned on. I am not having any of the freezing issues I had previously, and it was working great. Was I wrong that it was a logic board issue? I am confused because I don't see how it could've fixed itself. But two weeks ago I turned the laptop off and took it on a trip. When I went to power it on, it wouldn't turn on again. Reseating the RAM fixed it once again. Why is this fixing it? The RAM works perfectly. Is it becoming loose? What should I do? I am confused because reseating it is definitely making it go from not turning on (no noise, no lights, nothing) to turning on and working perfectly. It's just inconvenient to have to unscrew everything and reseat it. So the main problem is, whenever I turn it off and leave it for a day or so, it won't turn on without reseating the RAM. Thanks for any help! I am planning on going on a 4 week trip next fall and won't be able to take the Mini with me. I am hoping to be able to get this working steadily enough that I can take it with me and avoid having to buy a used laptop.
