When Password Status is Locked, type the password and press <Enter> when prompted at reboot.

If an incorrect system password is entered, the system displays a message and prompts you to re-enter your password. You have three attempts to enter the correct password.

Even after you shut down and restart the system, the error message is displayed until the correct password is entered.

NOTE: You can use the Password Status option in conjunction with the System Password and Setup Password options to protect your system from unauthorized changes.

Operating With A Setup Password Enabled

If Setup Password is Enabled, enter the correct setup password before modifying most of the System Setup options. If you do not enter the correct password in three attempts, the system displays the message

Invalid Password! Number of unsuccessful password attempts: <x> System Halted! Must power down.

Even after you shut down and restart the system, the error message is displayed until the correct password is entered. The following options are exceptions:

If System Password is not Enabled and is not locked through the Password Status option, you can assign a system password.

You cannot disable or change an existing system password.
