Smart Cover Lock
✎The Smart Cover Lock is an optional feature included on select
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

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
ÄCAUTION: The Smart Cover FailSafe Key is a specialized tool available
from HP. Be prepared; order this key before you need one.
To obtain a FailSafe Key:
■Contact an authorized HP reseller or service provider. Order PN
166527-001 for the wrench-style key or PN 166527-002 for the
screwdriver bit key.
■Refer to the HP Web site (www.hp.com) for ordering information.
■Call the appropriate number listed in the warranty.
