Hi @SandeepSingh1 

Welcome to the HP support community.
 

I understand you're experiencing an issue with your HP device, and I apologize for any inconvenience this may have caused. I'm here to help you today.

Please try these steps:

Shut down the computer, and then inspect and clean the exterior vents to remove dust buildup by blowing air through the vent openings. Dust can accumulate inside the vent openings and around internal cooling components, preventing the removal of heat.
To be able to assist you better please let me know the Operating System installed on your computer

Installing the BIOS update

Download and install a BIOS update from the HP website.

Go to the HP Software and Driver Downloads page.

Navigate to the product page for your computer.

Select BIOS from the list that displays, and then review any available BIOS updates.

CAUTION:

Read the Details section to confirm that the BIOS update is more recent then the one installed and that it applies to your computer. Installing the wrong BIOS could cause your computer to stop working.

If you do not see a BIOS update listed for your computer, no update is currently available.

If there are multiple BIOS updates available, identify the motherboard installed on your computer using the information from the System Information utility.

If you find a BIOS update, click Download. If HP Download and Install Assistant displays, select Download only, and then click Next. Click Save to save the BIOS update file on your computer.

Browse to the folder or desktop where you saved the downloaded BIOS update file, and then double-click the file name (example: sp12345) to start the installation.

The computer might beep, turn off and on the display or cooling fans, or display a blinking power light. This is normal.

CAUTION:

Do not turn off or restart the computer until the update process completes.

I hope this helps! Keep me posted.
