The most likely reason for this problem to occur is that the user has turned Num Lock on, causing the keyboard to register numbers instead of letters.
When a user tries to log into Windows on their notebook computer and enters the correct password for their user account, but the system won't let them authenticate, claiming the wrong password has been entered, the most common cause of this problem is that the Num Lock key has been turned on, causing the keyboard to register numbers instead of letters.
When the Num Lock key is enabled, the keyboard's numeric keypad is activated, which can lead to a password being entered incorrectly if it contains letters rather than numbers. As a result, the user's login attempts will be denied.To fix this problem, the user should check whether the Num Lock key is turned on and turn it off if it is.
The Num Lock key is usually located near the top of the keyboard and is labeled with an indicator light that turns on when it is enabled. If this does not solve the problem, the user may need to check whether the Caps Lock or Scroll Lock keys have been enabled, as these can also cause issues with login authentication.
