What should I do if the Enter Onetime Password message appears and Windows does not start after I enter a wrong power-on password three times consecutively?
Press and hold down the(Power) button for more than 4 or 10 seconds. If your VAIO computer is equipped with the power indicator, check that it is off. Then, restart the computer and enter the correct password.
The password is case-sensitive, so be sure to check letters for the current case before you enter the password.
If you forget the power-on password, you cannot start your VAIO computer. See What should I do if I forget the power-on password to start my VAIO computer? for more information.
