							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.
