I recently preformed a Bios update to my old laptop (HP pavilion 6604nr) using one under HP's site under my model. I turned away for alittle while, while it flashed and when I turned back the screen was black. Upon restarting the screen will not display an image. I do hear windows start up. I think I might need to preform a Bios reset/restore, but i'm not sure. Any ideas, maybe im wrong? It was working fine, i had just installed windows 7 on it (ubuntu was on it before) I was testing it out.
