Unlocking the Smart Cover Lock

NOTE The Smart Cover Lock is an optional feature included on some models only.

The Smart Cover Lock is a software-controllable cover lock, controlled by the setup password. This lock prevents unauthorized access to the internal components. The computer ships with the Smart Cover Lock in the unlocked position. For more information about locking the Smart Cover Lock, refer to the Desktop Management Guide on the Documentation and Diagnostics CD.

Smart Cover FailSafe Key

If you enable the Smart Cover Lock and cannot enter your password to disable the lock, you will need a Smart Cover FailSafe Key to open the computer cover. You will need the key to access the internal computer components in any of the following circumstances:

Power outage

Startup failure

PC component (for example, processor or power supply) failure

Forgotten password

NOTE The Smart Cover FailSafe Key is a specialized tool available from HP. Be prepared; order this key before you need one.
