Safety Instructions
Use the following safety guidelines to protect your computer from potential damage and
ensure your personal safety.
WARNING: Before working inside your computer, read the safety
information that shipped with your computer. For additional safety
best practices information, see the Regulatory Compliance
Homepage at dell.com/regulatory_compliance.
WARNING: Disconnect all power sources before opening the
computer cover or panels. After you finish working inside the
computer, replace all covers, panels, and screws before connecting to
the power source.
CAUTION: Only a certified service technician is authorized to remove
the computer cover and access any of the components inside the
computer.
CAUTION: To avoid damaging the computer, ensure that the work
surface is flat and clean.
CAUTION: When you disconnect a cable, pull on its connector or on
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.
CAUTION: Before touching anything inside your computer, ground
yourself by touching an unpainted metal surface, such as the metal
at the back of the computer. While you work, periodically touch an
unpainted metal surface to dissipate static electricity, which could
harm internal components.
CAUTION: To avoid damaging the components and cards, handle
them by their edges and avoid touching pins and contacts.
