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 more safety best practices, see the
Regulatory Compliance home page 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: To avoid damaging the computer, make sure that the work surface is
flat and clean.
CAUTION: To avoid damaging the components and cards, handle them by their
edges and avoid touching pins and contacts.
CAUTION: Only a certified service technician is authorized to remove the
computer cover and access any of the components inside the computer. See the
safety instructions for complete information about safety precautions, working
inside your computer, and protecting against electrostatic discharge.
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: 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, make sure 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: Press and eject any installed card from the media-card reader.
