Hello.

I was working on my laptop and then the power came off and the laptop shutdown because i work without a battery. After the came power on again the keyboard and the touchpad of the laptop are disabled in windows 7 but they work on startup and bios. I have tried making changes in bios but with no luck and i tried an external keyboard and mouse but didnt work too. So how I solve this ?
