Troubleshooting overheating symptoms

You can try these easy troubleshooting steps to reduce the overheating on your system:

  • Make sure the system is in a well ventilated area

  • Use laptops on flat surfaces to improve airflow. Hard table tops are recommended and avoid using any type of cloth or any other soft material under the laptop

  • For desktop systems make sure there is enough clearance around the system to allow the air to flow. If the system is in an enclosure try to move it to a more ventilated area for testing

  • Check that the air vents are clean and that there is nothing obstructing them. See General Maintenance For Maintaining Your Dell Computer for instructions on how to clean your system
