Installation Sequence
It is very important that you follow this sequence of steps to ensure
the proper installation of any optional equipment.
1. If your computer includes the Smart Cover Lock feature and you
have set the lock, use Computer Setup to unlock the lock and
disable the Smart Cover Sensor.
For more information about Computer Setup, refer to the Computer
Setup (F10) Utility Guide.
2. If the computer is already on, turn it off and disconnect the power
cord from the wall outlet.
ÅWARNING: To reduce the risk of personal injury from electrical shock
and/or hot surfaces, be sure to disconnect the power cord from the wall
outlet, and allow the internal system components to cool before
touching.
ÅWARNING: To reduce the risk of electrical shock, fire, or damage to the
equipment, do not plug telecommunications or telephone connectors
into the network interface controller (NIC) receptacles.
ÄCAUTION: Static electricity can damage the electronic components of
the computer or optional equipment. Before beginning these
procedures, ensure that you are discharged of static electricity by briefly
touching a grounded metal object. See Appendix E, “Electrostatic
Discharge,” for more information.
3. Open the computer by removing its outside cover. See the section
“Removing the Access Panel.”

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 in any of the following
circumstances:
■Power outage
■Startup failure
■PC component (for example, processor or power supply) failure
■Forgotten password
