When Working Inside Your Computer
Take note of these safety guidelines when appropriate.
NOTICE: 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 in on 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 that both connectors are correctly oriented
and aligned.
