L100 is stuck on the startup menu (black and white screen)Not ready my keyboard so cany reboot
What Startup Menu? Exactly what is on the screen? Has the computer completely booted to your Windows Desktop so that you see your icons and the Start Menu at the bottom left portion of the screen? if so why are you trying to use the keyboard? I think you should be using your mouse to point an click on something, then use the keyboard if needed.
Maybe your keyboard has gone bad and needs to be replaced. What type of keyboard connection do you have PS2 (serial) or USB? A USB keyboard has the square flat end that plugs into the computer, it can be pulled out and plugged back into the computer anytime because it is Plug and Play. The PS2 (serial) keyboard has a round end that plugs into the purple port in the computer. IT IS NOT PLUG AND PLAY. If you unplug it while the computer is on, your computer will freeze and not recognize the keyboard.You have to reboot anytime you unplug the PS2 (serial) type of keyboard.
Anyway, if your keyboard is frozen then maybe a virus or infection has hijacked it. Try booting into Safe Mode and see if it works.
