Hello SevenForums!

I've updateted my laptop Toshiba Satellite C660-13R with the latest bios update 1.70 and from since then i have a strange problem that i don't thinκ that existed before. When the charger is pluged in and i try to activate it it starts but it shows black screen. I need to press the power button for several seconds to do a hard shutdown, and then activates normaly. Without the charger it activates normally. Can you please provide me the factory BIOS.ROM file to try out, hopefully that the problem disappear? Thank you.
