8| Before You Begin

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.

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 connectors and ports

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.
