hen Working With Your
Computer
Take note of these safety guidelines when appropriate:
•
To help avoid possible damage to the system board,
wait 5 seconds after turning off the system before
disconnecting a peripheral device from the
computer.
•
When you disconnect a cable, pull on its connector
or on its strain-relief loop, not on the cable itself.
Some cables have a connector with locking tabs; if
you are disconnecting this type of cable, press the
locking tabs before disconnecting the cable. As you
pull connectors apart, keep them evenly aligned to
avoid bending any connector pins. Also, before you
connect a cable, make sure both connectors are cor-
rectly oriented and aligned.
