I suspect a hardware problem, but get hold of a bootable CD and see if you get anything on the screen with it. You can use a Windows install disc, Toshiba recovery disc, Windows 7 repair disc, UBCD or Ubuntu disc. If you don't get anything on the screen with these, you need to take your laptop to a service technician.
Press the power button, straight to black screen.
No BIOS, just power light and the sound of the hardrive and dvd drive booting up. Used vga cable to attach another monitor, still black.Took hardrive out and retrieved data to PC, so that seems ok.. Laptop has been advising battery replacement prior to crash which I've now done. Still straight to blackscreen. Pretty noob on these things. Really would appriecate any advice.
