...comes back with 8 dead pixels!!!. I sent my Powerbook G4 17" 1.5ghz to Texas to get the whitespot repaired, before I gave it to the genius bar, i specifically checked for dead pixels and i didn't have a one. I recieve the computer first thing in the morning at my office but i didn't open it till i got home then I counted 8 dead pixels???? What happened does anyone know?
