HP EliteBook 850 G3 Fan Replacement

Introduction

If your HP EliteBook 850 G3 is overheating and the fan is not operating, use this guide to replace the fan. Fans are used to draw cooler air into the case from the outside, expel warm air from inside and move air across a heat sink to cool various components. When a fan is faulty the computer may overheat and perform sub-optimally, and also potentially shut down under heavy loads. Before using this guide, feel free to check out the troubleshooting page to see if any issues can be resolved without a replacement.
