Ejecting the optical (CD or DVD) 
drive tray
To eject the tray of an external IEEE 1394-compatible optical drive, 
press the eject button on the external drive (PC must be powered on).
When the power is off, you can eject the drive tray using the 
emergency eject hole.
Insert a straightened paperclip into the hole to perform an eject.
Using a computer security lock
A security keylock notch, located on the right hand side of the 
computer, lets you connect a Kensington-compatible computer 
security lock.
Wrap a computer security lock cable around an immovable object such 
as a table or handle of a locked drawer. Insert the lock into the notch 
and turn the key to secure the lock. Some keyless models are 
also available.
