HP EliteBook 8470p Fan Replacement

Einleitung

The fan in this laptop ensures that all the components are at a temperature where they can perform to the user’s standards. It is located inside the laptop in the upper left corner.

A fan that is damaged or broken could lead to overheating and a loss of performance in the laptop. Things to look for are your keyboard feeling warm, the laptop freezing for no apparent reason, and a lack of air dispersed from the laptop's exhaust ports.

This step should be completed after removing the battery and service cover from the underside of the computer.
