lenevo thinkpad 11e redefinição de senha

Question

Eu tenho um laptop Yoga 11e Thinkpad e não posso fazer escolhas no BIOS.

Ele pede uma senha, e se você responder incorretamente 3 vezes, você poderá entrar na BIOS, mas não poderá fazer nenhuma alteração.

Se eu deixar que ele inicialize até o fim, aparece uma tela que me permite escolher como gerenciador de inicialização, ata hddo: e pci lan, instalação, tela de diagnóstico e diagnóstico de lenevo, mas não me permite escolha qualquer uma das escolhas.

Como posso resolver isso?

    

Answer 1

Como posso remover as senhas do BIOS?

Existem 3 tipos de senhas. Não está claro a partir de sua pergunta qual deles você precisa remover.

As many as three passwords may be needed for any ThinkPad notebook computer: the power-on password, the hard disk password, and the supervisor password.

If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the computer is turned on. The computer does not start until the password is entered.

Note: If only a supervisor password is set, the password prompt will not be displayed when the operating system is started.

Power-on password

A power-on password protects the system from being powered on by an unauthorized person. The password must be entered before an operating system can be started. For instructions on how to remove the power-on password, see “How to remove the power-on password” on page 33.

Hard disk password

There are two kinds of hard disk passwords:

• User hard disk password - for the user
• Master hard disk password - for the system administrator, who can use it to get access to the hard disk even if the user has changed the user hard disk password

Note: There are two modes for the hard disk password: User only and Master + User. The Master + User mode requires two hard disk passwords; the system administrator enters both in the same operation. The system administrator then provides the user hard disk password to the system user.

Attention: If the user hard disk password has been forgotten, check whether a master hard disk password has been set. If it has, it can be used for access to the hard disk drive. If no master hard disk password is available, neither Lenovo nor Lenovo authorized service technicians provide any services to reset either the user or the master hard disk password, or to recover data from the hard disk drive. The hard disk drive can be replaced for a scheduled fee.

For how to remove the hard disk password, see “How to remove the hard disk password” on page 34.

Supervisor password

A supervisor password protects the system information stored in the ThinkPad Setup. The user must enter the supervisor password in order to get access to the ThinkPad Setup and change the system configuration.

Attention: If the supervisor password has been forgotten and cannot be made available to the service technician, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee.

How to remove the power-on password

To remove a power-on password, do the following:

If no supervisor password has been set, do the following to remove the power-on password:

1. Turn off the computer and disconnect ac power.

How to remove the hard disk password
