Laptop or notebook processor is running very hot

This troubleshooting document is intended only as a guide to resolve various issues with laptops and/or notebooks. Ultimately, your laptop/notebook system manufacturer or mobile motherboard manufacturer may have the very latest information to help resolve your issues.

Important Note Disassembling, assembling, upgrading and troubleshooting computers should be performed only by a computer professional since the electronic devices may cause serious damage to the installer, the system, and its components if it is done improperly. Before attempting to disassemble or assemble laptop computers, carefully review the documentation specific for the laptop computer and its related components. Make sure that you will not be voiding the warranty of the system by opening the laptop computer or replacing any of the components in the laptop computer. Lastly, make sure to follow Electrostatic Discharge (ESD) procedures.
  • You should make sure that the laptop computer supports the processor that you are installing including type of processor, socket type, speed, and voltage. In addition, make sure that you do not run the processor at a faster speed than indicated on the processor. Lastly, you will need to check if there are any settings in the CMOS setup program that need to be configured on the laptop computer including those that indicate the speed of the processor.
  • If the high temperature is being reported by software or the BIOS setup program, check to see if the system feels warm. If the system feels warm, the readings are probably correct. If not, your system may need a BIOS upgrade. Contact your laptop vendor or manufacturer.
  • Make sure that the processor fan is connected properly and running properly.
  • Make sure that there the air intakes for the fans are unobstructed.
  • Make sure that the thermal interface material is applied properly. If you have removed the heatsink fan after initially installing the processor, you should replace the thermal interface material. Since the thermal interface material is different between laptop manufacturers, you must contact your laptop vendor or manufacturer to get the correct thermal interface material for your laptop and processor (those that indicate the speed of the processor).
  • Swap the processor with a known good replacement. If possible, try the suspect processor in another notebook or try a known good processor in the suspect system.
  • If the problem still exists or you determine that the processor is defective, contact your laptop vendor, system manufacturer, or place of purchase.
For more information on thermal specifications, processor power specifications, or on Enhanced Intel SpeedStep® Technology in general, please refer to explanation provided in each processor's datasheet:
