my Laptop, a toshiba sattelite 15.6" screen, will turn non fine, and will run normally, thats all fine and dandy, but what im concerned about is that my computer, after going completely into idle mode where the screen is black, after the screensaver, and when i move my trackpad or press buttons, the backlight comes on, but the screen wont come back to the page i was on, ive looked online and found nothing about this particular problem with a laptop, anyone know what's to blame?
