Using Passwords The password-setting feature helps to prevent your computer from being used by others. Once you set a password, a prompt appears on the screen each time you turn on the computer. You must enter your password at the prompt. You cannot use the computer unless you type the correct password. You can set the following passwords on your computer: Power-on password Set the power-on password to protect your computer from use by another person. It provides the following security features: - You need to type the power-on password at startup. Therefore, unauthorized users cannot use your computer. - You need to type the power-on password when resuming from suspend mode. Therefore, unauthorized users cannot use your computer. Hard disk password The hard disk password provides an extra measure of security. Even if you set a power-on password, another user can remove the hard disk drive in your computer and put it in a different computer to access your data. If you set a hard disk password, however, another person cannot access the data on your hard disk without knowing the password. It provides the following features: - You need to type the hard disk password at startup. - If the hard disk drive is moved to another computer, the hard disk password must be typed at startup. Therefore, unauthorized users cannot access your hard disk even if the drive is removed from the computer. Note: The hard disk password might be disabled by your system administrator. Setup password The setup password is a tool provided for the system administrator to control many ThinkPad computers. The setup password is set by the system administrator and it is not required for users. 76 ThinkPad 390 User's Reference
