A high hand of salute! I've a Toshiba Satellite P200 Laptop with Vista Home Premium. As of this past August, I've had the great joy of having the screen flicker and sometimes going totally blank while running this machine on battery power. The problem only appears while running on battery, and never on the AC. I've placed a new battery in this laptop, but it made no change. The Toshiba tech actually thought it would be the battery, but obviously that isn't correct. Is this something anyone here has heard about and overcome, or should I have a fire extinguisher close at hand in anticipation of this thing going up into a ball of bright orange flame? I'll appreciate your feedback and help. Thanks.
