Tips for Proper Usage

  • Dell does not recommend placing portable systems directly on your lap. Due to reductions in the thickness of modern portable systems, heat transfer can be an issue.
    NOTE: During normal operation, the temperature of the bottom of a portable system may exceed comfortable levels for sustained contact. It is possible that skin irritation could result from prolonged contact to the system chassis.
  • Using a portable system (Laptop) on a hard, flat, non-cloth surface will increase airflow and reduce heat from underneath and inside the system.
    Using the portable system on blanket, pillow, or other type of cloth will cover up the fan cause the computer to overheat and can cause permanent damage.
  • It is recommended to use the portable system in a Room temperature of 0°C to 35°C (32°F to 95°F) with a Humidity level no greater than 90%. For specified environmental usage temperatures for your system refer to your User's Guide or Setup Guide
  • Use compressed air to clean the vents on a regular basis.
  • Using a cooling pad can decrease heat and increase performance.
  • If you want to know the temperature limitations fo you system, fo to the Dell Support Website, look up your system model then open the user guide under the manuals link.

Cleaning the Vents

  1. Check the vents on the computer to see if they are covered with dust and not allowing heat and air to pass through.
  2. Turn off the System
  3. Unplug the AC Adapter
  4. Remove the Battery, for instructions on how to remove the battery see the Service Manual.
  5. Use Compressed Air to blow the dust out of the vents.
    Do not use your mouth to blow the Dust out of a portable system. If using a can of compressed air use the can according to the directions on the side of the can as you can cause damage to the computer if used incorrectly.
