My 2009 Macbook Pro seems to have a problematic DIMM1 slot. I previously upgraded my MB Pro from 4GB to 8GB of ram, everything was fine until today (or at the very least, I only noticed it today). I opened the system properties and noticed that the system indicated 4GB, instead of 8GB. Popped open the back and did the following: 1. Switched the ram from DIMM0 to DIMM1 -Same issue, DIMM1 not indicating anything. Ram verified working 2. Popped out DIMM0 -Failed. Popped it back out, suddenly worked. 3. Installed DIMM0 and DIMM1 -DIMM1 failed again. 4. Reinstalled DIMM0/DIMM1 -Everything suddenly worked I'm led to believe that the DIMM1 slot is being weird. However, I can't concluded that it's a fully defective considering it's working again. Should I be concerned at all with these observations? PS: The primary reason in which I'm concerned is that I dropped my computer a few weeks back. Fell roughly 2-3 feet onto tile like flooring. The screen corners (near the hinge) bent inwards and pushed in (dented) the metal corners near the keyboard.
