I just installed new memory in my macbook pro (2.4 penryn if it matters). I know its the right memory and whatever Muskin (2x2gb). It was easy enough, I followed all of the instructions and was done it like 3 minutes. When I tried to start the POS up it made these loud beeping sounds like an alarm and the sleep indicator thing on the latch kept beeping. Well, I knew that wasn't good I so had to remove the battery to get the thing to stop making that horrible sound. I then proceded to put the original memory back in and give it a try. The same thing happened. So now this damn thing won't work at all. Does anyone know what the hell just happened. How do I so called easy upgrade go so damn wrong. I'm guessing I'm going to have to take this thing to the genius bar, which sucks cause I hate going in that horrible apple store.
