Chapter 4. Security

This chapter provides information about how to protect your computer from unauthorized use.

Locking your computer

This section provides instructions on how to lock your computer with the locking devices to keep your 
computer safe.

Locking the computer cover

Locking the computer cover helps prevent unauthorized people from gaining access to the inside of your 
computer. Your computer might come with a key lock that is built into the computer cover. The keys for the 
key lock are attached to the rear of the machine. For security, store the keys in a secure place when you are 
not using them. Lenovo does not accept responsibility for any loss of keys. 

Note:

The key lock and keys are available only on some models.
