Hi, Vectorworks stopped working on my laptop this afternoon, so I restarted my cpmputer asuming it was something to do with the dongle. Since restarting it, it won't start. I press the power button, and the grey screen with the apple comes up, and no startup tone - taking into account that I muted my speakers before restarting the computer because I was in the library. So, I'm willing to try anything. I have the OSX restore CD's ready, but when I insert them nothing happens. I've reset the PMU (or whatever it's called), and I've tried holding down shift when booting up. Nothing. Any help would br greatly appreciated - can't send laptop away as am 2 days away from a major Final Term deadline and all files are on laptop - as you can see I'm desperate! Please help in any way you can. Laptop Specs: Powerbook G4, 1.5 about 25Gb free gard drive space. About 2 years old - did an OS restore 2 months ago due to different problems and have had no problems since. Cheers!
