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: 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: To avoid damaging the computer, make sure 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, make sure that the ports and
connectors are correctly oriented and aligned.
CAUTION: To avoid damaging the components and cards, handle them by
their edges and avoid touching pins and contacts.
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: Press and eject any installed card from the media-card reader.
