Lenovo G70-70 Fan Replacement

If your Lenovo G70-70 laptop frequently turns off while you are working on it and the bottom of the laptop feels hot, use this guide to replace the fan.

Before using this guide, inspect the vents above the fan for debris that may prevent airflow to the internal section of the laptop. Typically, a small buildup of dust can be removed with a small brush or a dust blower. This repair is necessary to keep the inside of your laptop cool so it can run properly.
