NOTE: If you are using a different operating system, see the
documentation of your operating system for shut-down
instructions.
3 Disconnect your computer and all attached devices from their electrical
outlets.
4 Disconnect all cables such as telephone cables and network cables, from
your computer.
5 Disconnect all attached devices and peripherals, such as keyboard,
mouse, and monitor, from your computer.

Safety instructions
Use the following safety guidelines to protect your computer from potential
damage and ensure your personal safety.
12
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
www.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 electrical outlet.
CAUTION: To avoid damaging the computer, ensure 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: You should only perform troubleshooting and repairs as
authorized or directed by the Dell technical assistance team. Damage
due to servicing that is not authorized by Dell is not covered by your
warranty. See the safety instructions that shipped with the product or
at www.dell.com/regulatory_compliance.
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, ensure that the ports and connectors are correctly oriented
and aligned.
CAUTION: Press and eject any installed card from the media-card
reader.
