I just bought a Hitachi 200GB 7200RPM hard drive for my macbook pro. I followed all of the instructions from fixit.com, and everything went smoothly hardware wise. With the new hard drive inside, and everything closed up, i try to turn on the laptop, BUT NOTHING HAPPENS! The white light on the front turns on, and the dvd-drive make a noise, and thats it. Nothing at all shows up on the screen, just black. No "baah" startup sound or anything. So I figured I need to insert my Leopard DVD to make it work. Didn't help me, and now I can't get the disc out! I'm afraid to call apple since I'm pretty sure they don't approve of taking their laptop apart. Somebody please help!
