Hi I I have a Lenovo ideapad and numbers 5 and 6 don't work on either the top row or the right hand side and I need these numbers for my system password to start windows so an external keyboard is no good either. Pls help.

The first test is if the USB external keyboard works. If it does that usually means (about 99%) of the time) the laptop keyboard needs to be replaced.

Just in case you don't know, on the login screen you can turn on the OSK (On Screen Keyboard) to log in if there is a keyboard failure.
Examples abound but here's a starter thread: https://social.technet.microsoft.com/Forums/windows/en-US/611f5858-87cb-4c04-9007-b0d7dc206c1e/how-can-i-make-the-on-screen-keyboard-display-at-the-login-page?forum=w7itproinstall
