I received my 2 x 1Gb RAM today and tried to install them onto my MacBook. Removing the standard 512mb memory was fine with no problems and I am sure that I inserted the new memory in the correct direction. When trying to boot up, my macbook displayed the sleep light but it did not boot up, I realised that i may not have pushed the memory hard enough into the slots, so I pushed it in further and turned on my Macbook and the sleep light still remained. I then carried on trying to push the memory in further and now the Macbook will not boot at all and not even the sleep light is displayed. I am a bit worried because my MacBook is under 2 weeks old. Do you think this would have void the warranty? I have tried removing the 1Gb memory but the levers will not release the memory therefore I am unable to remove them! I am not sure whether I pushed the memory too hard in because I had read that a considerable amount of force is needed. Can anyone help?
