Processor is Not Identified Correctly by the Operating System or an Application

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 attempt 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.

  • Since many programs detect the processor so that they can better utilize their features, the software may have been written before the processor existed. Therefore, check with the software manufacturer for a patch.
    Note If an application cannot identify a processor, the software will not run with the processor or it will assume it is an older processor without many of the features that the processor offers resulting in slower performance.
  • You should make sure that the laptop computer supports the processor (including type of processor, socket type, speed, and voltage.)

  • Make sure that you do not run the processor at a faster speed than is indicated on the processor. (over clocking)
  • 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.
  • Check the CMOS setup program for processors settings.
  • Your system may need a BIOS upgrade. Contact your laptop vendor or system manufacturer to see if you need to update to the newest BIOS version.
  • 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.
