8.2 Unlocking the Smart Cover Lock
If you have locked the Smart Cover Lock use Computer Setup to unlock the lock. Refer to the
Desktop Management Guide on the Documentation CD for more information about the Smart
Cover Lock.
If you cannot access Computer Setup to unlock the cover you will need to remove the locking
solenoid by using the Smart Cover FailSafe Key (Spare part number 166527-001 or
166527-002). Once the solenoid has been deactivated or removed the access panel can be
removed.
The Smart Cover FailSafe Key will be needed in any of the following circumstances:
■ Power outage
■ Startup failure
■ Processor or power supply failure
■ Lost password
1. Using the Smart Cover FailSafe Key, remove the two tamper-proof screws that secure the
Smart Cover Lock to the inside of the chassis.
2. Remove the computer cover.
To reattach the Smart Cover Lock, secure the lock in place with the two tamper-proof screws.
