Hi There. I am Bing and I look forward to helping you with your issue today.
I would prefer seeing a screenshot of the message which may also tell the info of OS, application as well environment, if possible?
Also do you feel noticeable heat around the fan area? Any performance decrease noticed? Do you often use the laptop on non-flag surfaces such as sofa or bed?
Hi, my name is ***** ***** I am happy to assist you today!
I see that you are getting a message regarding your laptop fan. On HP models, this usually means that either the main fan is immobile or broken.
In the event it is immobile, sometimes taking off the back cover and using canned air to clean the fans can get it working again. However, if it does not, it likely means the fan will need to be replaced, in which case you will need to reach out to HP support at http://www8.hp.com/us/en/contact-hp/support.html.
Let me know if you have any further questions or if there is anything else I can do.
