Just a short question. How long does it take on a powerbook G4 (1.67 Ghz) from pressing the On button to the grey screen with the Apple Logo. I ask this because My Powerbook has the known lower RAM slot problem and it takes about 10-15 seconds before the grey screen with the Apple logo shows up. Is this a normal time? I bought this Powerbook about 2 years ago, doing well except the lower slot is "non functioning" Would it be faster if I remove the 512MB Dimm, actually stupid question, I can easily try that out myself.
