The CPU is not detected.
Contact support for repair due to system board or CPU failure.

 

It states that the CPU/Processor is not detected.  Unless you are very tech savvy, I suggest taking the laptop to a reputable computer shop for repairs.  If the laptop is still in the warranty you should contact HP Customer Support and give them this information.

Please click the Thumbs up + button if I have helped you and click Accept as Solution if your problem is solved.
