Hello.

Overheating means your laptop is turning off abruptly or reducing performance to keep the system under the maximum operating temperature. Are you experiencing either?

Is the fan working? If it doesn't work, either it is broken - or full of dust, lint, debris and needs to be cleaned. A non-functional fan should cause an error message to be shown whenever the computer is turned on.

HP has a support document "Reduce heat inside the laptop to prevent overheating in Windows". Try the cleaning procedures first.

Finally, try updating the BIOS to latest v01.30.00 version from the support download page. The BIOS updates may have changed the fan curve settings to more aggressive.

There is a setting in BIOS called Fan Always on while on AC Power which is self-explanatory. Even if you don't enable it, the computer will ramp up the fans if temperature gets too high. Leaving it on will keep the laptop cooler in low-power scenarios.

Finally, try resetting the Windows power settings to their default and try the Balanced power profile instead of High Performance to see if it makes a difference.
