Prospective users will have to know the proper passwords in order to access your computer or data. You can set the following passwords: Power-on passwords Screen-saver passwords Hard-disk passwords Windows password Supervisor password Network password Passwords and standby mode Power-on passwords You can set a power-on password to help protect your ThinkPad computer against access by unauthorized users. If you set a power-on password, the password prompt appears on the screen when you turn on the computer. You must enter the correct password to start using the computer. Note: If you forget your power-on password, you cannot reset it. You must take the computer to an IBM reseller or IBM marketing representative to have the password canceled. Screen-saver passwords You can set a screen-saver password. Once the screen saver has started, only those who know the password can exit the screen saver and resume operating the computer. Note: The screen-saver password does not thoroughly protect your computer from unauthorized users. An unauthorized user could turn the computer off and then on to restart Windows without knowing your screen saver password. 24 ThinkPad X20 User's Reference Using passwords To set a screen-saver password, refer to the Online User's Guide. Hard-disk passwords Two types of hard-disk password can help protect the information stored on the hard disk. User hard-disk password Master hard-disk password, which requires a user password When a user hard-disk password is set, but no master hard-disk password is set, no one can access to files and applications on the hard-disk without first typing that password. The master password can be set and used only by a system administrator. Like a master key, it enables the administrator to get access to any hard drive in a system. The administrator sets the master password, and no one else knows it. Then the administrator sets a user password for each computer in the network, and tells each user the password for his or her computer. The user can then change the user password as desired; the administrator can still get access by using the master password. If the user hard-disk password is different from the power-on password, a preset timer or an incoming call will not cause the computer to resume operation. To use the unattended resume function with a hard-disk password, set the same password for both the power-on password and the user hard-disk password. Attention If you forget your hard-disk password, there is no way to reset your password or recover data from the hard disk. You must take your computer to an IBM reseller or marketing representative to replace the hard disk drive. A fee will be charged for parts and service. To set a hard-disk password, refer to the Online User's Guide. Chapter 4. Protecting your computer 25 Using passwords Windows password When you start your ThinkPad® computer and the Windows® operating system opens, Windows requires you to enter a user ID and a password. To set a Windows password, refer to the Online User's Guide. Supervisor password The supervisor password protects the system information stored in the BIOS Setup Utility so that without knowing the password, nobody can change the configuration of the computer. Attention If you forget your supervisor password, there is no way to reset it. You must take your computer to an IBM reseller or marketing representative to replace the system board. A fee will be charged for parts and service. To establish a supervisor password, refer to the Online User's Guide. Network password If you work on a local area network (LAN) with your ThinkPad computer, your LAN administrator may have set passwords to restrict access to various parts of the network. If you are authorized to access restricted areas of your LAN, you will need to establish network passwords in Windows. To establish your network password in Windows, refer to the Online User's Guide. Passwords and standby mode If you have set passwords and you put your computer into standby mode by pressing Fn + F4, the procedure for resuming operation is as follows: 26 ThinkPad X20 User's Reference Using passwords Press the Fn key, you will be prompted to type your password. You must enter a power-on password or a supervisor password (if one is set). If any hard disk has a hard-disk password, it is unlocked automatically when you resume operation. If you use a hard-disk password with a hard disk in a docking station, follow these procedures to ensure smooth docking and undocking. If you dock your computer to the docking station while the computer is running, make sure that it is in standby mode. (Press Fn + F4 to put it in standby.) To resume operation, press the Fn key and type the passwords as you are prompted. Note: If your computer is running, do not attach it to a docking station without first putting it in standby mode. If you do, you will be unable to access the password-protected hard disk in the docking station. Chapter 4. Protecting your computer 27 Using the locks Using the locks Attaching the mechanical lock You can attach a mechanical lock to your computer, to help prevent it from being removed without your permission. Attach a mechanical lock to the keyhole of the computer; then secure the chain on the lock to a stationary object. Refer to the instructions shipped with the mechanical lock. Note: You are responsible for evaluating, selecting, and imple- menting any locking devices and security features you use. IBM makes no comments, judgments, or warranties about the function, quality, or performance of locking devices and security features. 28 ThinkPad X20 User's Reference Chapter 5.
