Hi, I have a 466 Graphite clamshell ibook that I bought used over a year ago...and ever since I've had it it will not start up easily ...I usually have to hold down the power button for 5 or so seconds then repeat for another 5 then tap it once more then it will start up.....I've tried norton and tech tool...but nothing works...any idea? It happens only when starting it up...it wakes from sleep mode fine I use OS 9.2 and OSX...makes no difference with both Systems On battery power and Plugging in. Any info would be appreciated. Thanks! Mark
