Before Working Inside Your
Computer
CAUTION: To avoid damaging the components and cards, handle
them by their edges and avoid touching pins and contacts.
Before You Begin
1 Save and close all open files and exit all open applications.

– Windows 8: Move your mouse pointer to the upper-right or lower-
right corner of the screen to open the charms sidebar, and then click
or tap Settings → Power → Shut down.
– Windows 7: Click or tap Start → Shut down .
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, network cables and so
on, from your computer.
5 Disconnect all attached devices and peripherals, such as keyboard,
mouse, monitor, and so on, from your computer.

Safety Instructions
Use the following safety guidelines to protect your computer from potential

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 ports and connectors 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.
