Tips for Proper Usage

  • Using a Laptop on a hard, flat, non-cloth surface will increase airflow and reduce heat from underneath and inside the system. 
    Using the Laptop 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 Laptop 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

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 Laptop. 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.
