The Computer Is Unusually Warm; An External Device Is Not Working - HP 443562-001 Getting Started

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. Then be sure to keep
all vents free from obstructions while you are using the
computer.
Ä CAUTION: To prevent overheating, do not obstruct vents. Use the computer
only on a hard, flat surface. Do not allow another hard surface, such as an
adjoining printer, or a soft surface, such as pillows or thick rugs or clothing,
to block airflow.
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 off during routine operation.

An external device is not working

Follow these suggestions if an external device does not
function as expected:
Turn on the device as instructed in the device user guide.
Some devices may not be powered by the computer, and
must be turned on before the computer is turned on.
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 an older one, is
compatible with your operating system. For compatibility
information, refer to the device manufacturer's Web site.
Be sure that the correct drivers are installed and updated.
Drivers may be available on a disc included with the
device or on the device manufacturer's Web site. For
