I've had my 15" powerbook g4 for the last 3 years. I started noticing problems earlier this year as my computer started taking longer and longer to load up. And now, I think it's died. Symptoms: -Startup chime sound when powered on -Screen doesn't come on at all -Superdrive seems to be trying to run, noise coming from it -Keyboard seems unresponsive (cant get it to do target disk mode or eject my install cd) Can anyone give me some suggestions on how I might fix this? or how I might be able to get my data off the hard drive? I tried hooking up the powerbook to an external monitor using the dvi-vga converter to a dell monitor but it seems like the computer isnt even sensing the monitor. I really need to get this computer fixed, ASAP. No longer have Applecare. Any idea how much it might cost to get it fixed? THanks!
