ok i am really really freaked out right now.. i am afraid i just broke my macbook. here is my story. this morn, i decided to see how hard it was to replace a hd in a macbook, so i followed the instructions and successfully removed and replaced the hd. i followed all of the instructions except i didn't let it cool off for half an hour. just like 30 sec. then i successfully started it up, put it to sleep, and left for church. then about half an hour ago, i returned, decided to check out replacing the ram. this time i didn't let it cool off at all, because it had been sleeping all this time. i did the same procedure, but as soon as i paid attention to the ram slots, i noticed an inconsistancy with the instructions. the levers that were supposed to push out the ram were on the right side, not the left. i just considered this a small issue, as the diagram inside the battery compartment showed them on the right, with the arrows pointing to push them left. so i pushed them left, and it was really hard to push out, but eventually, the ram protruded just enough for me to grab it. then, i checked it out for a sec, and put it back in. i put it in the same direction, with the notch facing the left, which was the same direction the online instructions and the little diagram in the battery bay said. it didn't seem to push all the way in, however, no matter how hard i pushed. then i (exctremely stupidly) did the same with the other ram slot. i eventually figured that that was as far as it would go in. but then when i replaced the ram door cover (the metal L thing with 3 screws) the foam padding stuff refused to shove in all the way, as if the ram wasn't all the way in. i replaced the battery and tried to start it up. nothing came up on the screen, but the sleeping light started blinking in a hard fasion. (not the dimming pattern when asleep). i turned it off by holding down the power button, took out the batterey and the ram cover, tried to push the ram in more, and got the same results as before. i replaced the battery cover, put the battery in, started it up, and this time, the battery sleep light just turned on, at full brightness, and that is what it stayed at. nothing else happened. i assume it needs the ram to start up, and it can't find any. fyi, i have the standard non-bto black macbook. purchased on thursday night at the apple store palo alto, and first used on friday. it has an unregistered applecare subscription on it, so i can take it in if they could help me. HELP! Update: it doesn't gong, but before it goes silent, it makes that hard drive searching sound. (at least i think thats what it is). i just realized that when i press the power button, the screen flashes white, then goes black. it does the same thing off batterey, with the power cord, and with the power cord without the battery.
