CAUTION: The AC adapter works with electrical outlets worldwide. However, power connectors and power strips vary among countries. Using an
incompatible cable or improperly connecting the cable to the power strip or electrical outlet may cause fire or equipment damage.
NOTICE: When you disconnect the AC adapter cable from the computer, grasp the connector, not the cable itself, and pull firmly but gently to avoid
damaging the cable.
NOTE: The computer turns on the fan when the computer gets hot. Fan noise is normal and does not indicate a problem with the fan or the computer.
CAUTION: Do not block, push objects into, or allow dust to accumulate in the air vents. Do not store your computer in a low-airflow environment,
such as a closed briefcase, while it is running. Restricting the airflow can damage the computer or cause a fire.

NOTICE: Your computer features Undock & Go™ technology that allows you to undock your computer without going into standby mode. Because the
computer may not automatically go into standby mode when it is undocked, be sure the settings in the Power Options control panel do not prohibit the
computer from going into standby mode. If you change the Power Options control panel to prohibit the computer from going into standby mode, you
greatly increase the chances of causing your battery to wear down quickly or causing your computer to overheat.
NOTE: The computer turns on the fan when the computer gets hot. Fan noise is normal and does not indicate a problem with the fan or the computer.
