Ok, it's like this; my ibook 600, 256 RAM, 20g drive, OSX Panther, a new purchase from powerbookguy.com, has been going along just fine until last night. I was opening a PowerPoint file when the screen went dead and the computer immediately went into sleep mode and could not be woken up. None of the keyboard commands would work - it could not be shut down with Force Quit. I unplugged it, disconnected the battery, reconnected it, and tried turning it on again, but nothing is happening; no delightful "Bonnnggg", no nothing. The battery power now reads a dismal single blinking light, when before it had a 3 hour charge. Any suggestions?
