Problems and Solutions

■Is the notebook positioned to allow adequate ventilation?

✎To prevent overheating, do not obstruct the vents. Do not allow a hard surface, such as an adjoining optional printer, or a soft surface, such as carpet or fabric, to block the airflow.

■Have files been scanned for viruses?

■Was the notebook shut down through the operating system? Failure to do so can corrupt files.

■If the problem relates to an external device:

❏Is the device securely connected?

❏Is the device receiving reliable electrical power?

❏Is the device turned on?

✎Some devices, such as monitors, printers, and parallel devices, must be turned on before the notebook is turned on.

❏Are all necessary device drivers installed?
