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.
