My daughter's white Macbook 1.83/60GB/512/MB arrived a few days ago. This morning, I upgraded the drive to a Hitchi 160GB SATA and upgraded the RAM to 2GB of G.Skill, using the instructions found in Apple's DUI video and this thread. I inserted the AC power adapter, pressed the ON button, and...nothing happens. The screen stays dark, and I can't hear the hard drive move. I think I saw the ON button glow green for a fraction of a second the first time I pressed it. But now, even the green fails to show. This was my biggest fear. I don't know whether I - failed to ground myself adequately when installing the hard dive or RAM, or -misinstalled the hard drive and RAM. The hard drive seemed to go in OK, but I was never able to hear a click when installing the RAM. Would poorly seated RAM or hard drive be enough to cause the LCD to stay dark? What if both were installed wrong? I have not yet installed the MacOS CD-ROM; I was afraid to insert the disk when the LCD is unlit and I can't hear the drive spinning. Where do I go from here?
