Should I be going thru HP for this? Shouldn't this be under warranty??
Expert:  Sandy replied 4 months ago.

Okay, please do the following:


If you notice that the system fan spins and is blowing warm air from the computer, clean the exterior vents to remove dust buildup by blowing air through the vent openings. Do this while the computer is off. Dust can accumulate inside the vent opening and around internal cooling components, preventing the removal of heat. After dust has been removed, try turning on the computer to see if the error goes away. if not, continue to the next step.

B. In some cases, updating the BIOS may help prevent this error from occurring. For information on how to update your BIOS, see Updating the BIOS.


Have the computer serviced to clean internal components and replace the system fan if necessary. Ensure that the following items are addressed during servicing:

  • Thoroughly remove dust from all internal cooling components.

  • Ensure that wires from the system and CPU fans are connected to the motherboard securely.

  • Ensure that the system fan blades spin correctly, and that the fan is not producing loud noises. If not working correctly, replace the system fan.

  • Remove old thermal compound from integrated circuits and heat sinks, and replace with new thermal compound.
