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.
