Problems with startup and speakers
I have a Powerbook G3 Wallstreet 233mhz with varying startup problems. Once I plug in the AC adapter, the fans spin very loud and the green light illuminates for a couple seconds. After that the computer becomes silent. When I press the power button, both speakers emit a buzzing/chirping sound and the system starts up. The buzzing/chirping sound continues as long as the computer is on. Sometimes the computer will get to the screen that says "Mac OS 9.2" and then display an error message with a bomb and it will say "A system error occured. Please restart your computer." I have already tried reseating the processor card and examining the hard drive. Any help is appreciated.
I can't believe it! I let the Powerbook G3 sit overnight without the battery or AC adapter plugged in and it works wonderfully again! Thanks everyone.
