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.
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 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.
