The computer is unusually warm
It is normal for the computer to feel warm to the touch while it is in use. But if the computer feels unusually
warm, it may be overheating because a vent is blocked.
If you suspect that the computer is overheating, allow the computer to cool to room temperature. Be sure to
keep all vents free from obstructions while you are using the computer.
WARNING! To reduce the possibility of heat-related injuries or of overheating the computer, do not place the
computer directly on your lap or obstruct the computer air vents. Use the computer only on a hard, at
surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft surface, such as
pillows or rugs or clothing, to block airow. Also, do not allow the AC adapter to contact the skin or a soft
surface, such as pillows or rugs or clothing, during operation. The computer and the AC adapter comply with
the user-accessible surface temperature limits dened by the International Standard for Safety of
Information Technology Equipment (IEC 60950-1).
NOTE: The fan in the computer starts up automatically to cool internal components and prevent
overheating. It is normal for the internal fan to cycle on and o during operation.
An external device is not working
Follow these suggestions if an external device does not function as expected:
Turn on the device according to the manufacturer's instructions.
Be sure that all device connections are secure.
Be sure that the device is receiving electrical power.
Be sure that the device, especially if it is older, is compatible with the operating system.
Be sure that the correct drivers are installed and updated.
