HP EliteBook 840 G4 Overheating

Over-time, dust gets inside the fan and doesn’t allow the fan to cool off the device as efficiently. In order to fix this, you will need to clean out the fan.

Leaving it exposed to hot temperatures for too long will cause the surface to become hot. In order to fix this, keep the HP in room temperature or cool environments.

Using the laptop on a bed or a blanket can cover the vents and trap the heat. In order to fix this, place the laptop on a hard, flat surface.
