Q: Why is my portable computer so warm?

A: This computer is designed to run demanding applications that may require the use of PC Cards, CD/DVD drives, and large amounts of memory. The computer complies with international safety standards for operating temperatures, including those of user accessible surfaces. However, as a result of the computer's power consumption while running these applications, it is normal for the external surfaces of the computer to feel warm when the computer is in use for extended periods.

Verify that the computer has adequate airflow. Check the space under, behind, and around the computer to determine if airflow is restricted. If the computer is not on a solid surface, like a desk or a table, this causes inadequate airflow under it and may cause one or both fans to turn on as well as to elevate the temperature of the computer's case.

Other reasons the computer may generate extra heat are as follows:

  • Portable computers are normally warmest when the battery is charging. If the battery is fully discharged, the unit runs warmer while the battery charges.
  • The use of PC Cards requires an extra amount of energy even when the card is not in use.
  • The use of a docking station or port replicator may generate extra heat.
  • Power settings set for maximum performance may generate extra heat. Modifying the power management settings for maximum power savings conserves power and reduces extra heat.

Note: If there is an issue where files are being lost or corrupted that is related to the heating, the hard disk, not the computer, may be generating the heat and causing the issue.

Some notebook computers have an updated BIOS that allows the notebook to cool the system by turning on the fan at more frequent intervals. For information on upgrading the BIOS on your notebook computer, select your notebook type from our Support Documents page, and then click Driver Downloads. The most current BIOS for your notebook is listed there.
