Important Handling Information
Turning on your MacBook Never turn on your MacBook unless all of its internal and
external parts are in place. Operating the computer when parts are missing may be
dangerous and may damage your computer.
Carrying your MacBook If you carry your MacBook in a bag or briefcase, make sure
that there are no loose items (such as paper clips or coins) that could accidentally get
inside the computer through vent openings or the optical drive slot or get stuck inside
a port. Also, keep magnetically sensitive items away from the MagSafe power port.
Using connectors and ports Never force a connector into a port. When connecting a
device, make sure the port is free of debris, that the connector matches the port, and
that you have positioned the connector correctly in relation to the port.
WARNING: Making adjustments or performing procedures other than those specified
in your equipment’s manual may result in hazardous radiation exposure.

MacBook or other property.
