8.2.1 Smart Cover Lock

The hp workstation xw4000 supports an optional Smart Cover Lock. This software-controllable lock prevents unauthorized access to the internal components when the Smart Cover Lock and setup password are enabled.

If you enabled the Smart Cover Lock, use Computer Setup to unlock it. If you cannot enter your password to disable the lock, you will need a Smart Cover FailSafe Key (Compaq spare PN 166527-001 or 166527-002) to open the computer cover. You will also need the key in any of the following circumstances:

■Power outage

■Startup failure

■PC component (e.g., processor or power supply) failure

■Lost password

ÄCAUTION: The cooling fan is off only when the computer is turned off or the power cable has been disconnected. The cooling fan is always on when the computer is in the “On,” “Standby,” or “Suspend” modes. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.

1.Prepare the computer for disassembly.

2.Using the Smart Cover FailSafe Key, remove the two tamper-proof screws that secure the Smart Cover Lock to the chassis. Use the special Compaq tamper-resistant T-15 wrench (PN 166527-001) or screwdriver bit (PN 166527-002) for this operation.
