I've tried everything. As soon as I turn on the laptop (Toshiba C55 Series) it just sits at the Toshiba Leading Innovation screen. I've taken out the battery, held down the power button, held 0, tried pressing F2, F3, F8... Everything. I can't even open the CD-ROM drive to put in a CD to boot from. No way to access BIOS because it does nothing. I wasn't doing anything on the laptop out of the ordinary before this. I only use it to browse the internet, never downloaded anything. What's going on? I can't get it to load with or without the battery, plugged in, doesn't matter. I really need some help.
