What's going on with the display on Toshiba Satellite A205-S4629?
Laptop will only boot when the AC adapter is disconnected, and then, the display will not display any characters, only a blank screen (but back lit). Once the system starts to boot, however, you can plug the AC adapter back in and it will continue to boot. With the screen being blank, I cannot tell what is actually taking place. All I get is drive activity for about 5 minutes or so, and then some type of musical alert (probably asking me for some type of response). I can't tell what type of response is necessary because I get nothing on the screen. I don't have an external monitor to plug into the VGA port to tell if the on-board video is bad or just the display. Any ideas on how to proceed?
