I can't log in because I can't type in the password. Only a couple of keys work. It was all fine yesterday. I don't know what happened to it. I've tried the on screen keyboard too. I have valuable data in my laptop. I can't reset it. Please help guys

Have you tried a USB keyboard?

You can't type anything in the password field with the onscreen keyboard?
