caps lock button not working properly on login screen

[Ankit Jain]

The caps lock button is not working properly on the login screen, it still shows there 'caps lock is on; message but entered letters are not capitalized.
Suppose I want to enter a password "SOMETHING" and I type it with the caps lock button on, it still types "something", with shift button this is working fine.
