You can set a password (power-on password) for booting up your VAIO computer, using the BIOS function. Entry of the power-on password will be prompted after the VAIO logo appears to start the computer.
There are two types of passwords. Set the machine password first.
Machine password (for administrators):
Allows users with administrative rights to change all the setup options in the BIOS setup screen, as well as to start your VAIO computer.
User password (for users without administrative rights):
Allows standard users to change some of the BIOS setup options, as well as to start your VAIO computer. To set the user password, you must first set the machine password.
The VAIO Care (Rescue Mode) screen appears.
Enter a password if it has already been set.
The BIOS setup screen appears.
The password entry screen appears.
To change the password, enter the current password and a new password. The password can be set up to 32 alphanumeric characters long (including spaces) and it is case-sensitive.
Be sure to write down the password to avoid forgetting it.
If you forget the password, you cannot boot up your VAIO computer.
You can reset the user password at the BIOS setup screen by entering the machine password.
If you forget the machine password, the password must be reset by authorized Sony service/support center. (The reset fee will be charged.)
