I am also having trouble rebooting my laptop (1.67Ghz,120HD,2Gb RAM,MacOs 10.4.9 or 10.4.11)
Have taken RAM out, swapped slots, done the PMA(?) reset, holdiing power key for 5-10 sec, ect. All with no luck.
Came back from holidays & it wouldnt get past the DVD check.
There is NO Vid display at all, not even a flicker.
the DVD seems be trying to eject maybe a DVD.
The batt was playing up before I left on holidays, charged to 99% full, take out power AC, at 75% would want to shut down cuz of low batt even though screen display said 75%.
Is there a button to push on the Board like on a desktop G4 logic board
Also had a different sound insted of the normal chime. like a "dong" sound, then the light on the front open switch flickered fast & brightly for about 5 secs.
What is the different sound mean foloowed by the rapid flickers of the light.???
Much appreciated for your advice please.
