Attaching a 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 security-lock slot 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 implementing the locking devices and security
features. Lenovo makes no comments, judgments, or warranties about the function, quality, or performance
of locking devices and security features.
Using passwords
You can help prevent your computer from unauthorized use by using passwords. Once you set a password,
a prompt is displayed on the screen each time you turn on the computer. Enter your password at the prompt.

If a Windows password has been set, you will be prompted to enter it.
