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.
