Hello Ragas,

Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.

I understand that the fan on your notebook is running faster than normal, and I would be happy to assist you in this matter!

Since an overactive fan is a symptom of overheating, I recommend following this document on Reducing Heat Inside the PC to Prevent Overheating. This should help slow the speed of your computer's cooling fan.

If the issue persists, please call our technical support at 1-800-474-6836. If you live outside the US/Canada Region please click the link below to get the support number for your region.

Thak you sir for your help...
The problem it is showing now is it tells on startup that " Your fan is not working properly. The pc will shutdown in 15 seconds."
What should i do now?

Hello Ragas,

Thank you for the quick reply!

A common fan error is 90b, which usually follows this line of text: "Continued operation is not recommended and may cause unpredictable behavior that could result in random shutdown, data loss or possible system damage. The system will shut down in 15 seconds. To prevent shutdown and continue operation, press the Enter key now."

To prevent this error message from appearing again, I recommend following this document on System Fan (90b) error message on startup. This should help treat the cause of the error message.

Please re-post with the results of your troubleshooting, and I look forward to your reply!

Hello Sir,
I have went through the document and i think the main cause is probably because of the dust so i think i should give it to hp centre for cleaning or servicing.
My laptop was with my sister for one month and because of not cleaning it for months dust have been collected inside
So should i give it to service centre or clean myself..
Thank You
Looking forward to your reply.
