CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of

your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.

CAUTION: To connect a network cable, first plug the cable into the network wall jack and then plug it into the computer.

NOTE: If an administrator password has been assigned by someone else, contact your network administrator for information on resetting the chassis

intrusion detector.

CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface. While you work, periodically

touch an unpainted metal surface to dissipate any static electricity that could harm internal components.

WARNING: Graphics card heat sinks can become very hot during normal operation. Ensure that a graphics card heat sink has had sufficient time

to cool before you touch it.
