Dell 5000 Series, Service Manual

Page: 7 / 40

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.
