Safety Instructions

and to help ensure your personal safety.

shipped with your computer. For more safety best practices
information, see the Regulatory Compliance Homepage at

WARNING: Only a certified service technician is authorized to
remove the computer cover and access any of the components
inside.
CAUTION: To avoid damaging the computer, ensure that the work
surface is flat and clean.

its pull-tab, not on the cable itself. Some cables have connectors with
locking tabs or thumb-screws that you must disengage before
disconnecting the cable. When disconnecting cables, keep them
evenly aligned to avoid bending any connector pins. When
connecting cables, ensure that the connectors and ports are
correctly oriented and aligned.
CAUTION: To disconnect a network cable, first unplug the cable from
your computer and then unplug the cable from the network device.
NOTE: Ensure that you remove the security cable from the security-cable slot,
if applicable.
