Asus K53E-BBR7 Fan Replacement

Introduction

The fan in your laptop is essential in keeping your laptop from overheating. If your device overheats this can cause damage to all internal hardware. If your fan fails, you must first remove the motherboard from your laptop.

Using the blue prying tool, separate the keyboard from the palm rest by inserting the prying tool into each of the five tabs at the top of the keyboard.
Slowly remove the keyboard by gently pulling the keyboard away from the palm rest.
A silver ribbon cable is connected to the keyboard and the palm rest of the laptop. Removing the keyboard quickly may tear the silver ribbon cable, causing harm to your device.

On a BBR1, which looks identical to the BBR7, the blue Ifixit prying tool is slightly too wide, at both ends, to fit in the tab slot. The Ifixit black spudger does fit. Don’t try to pry the keyboard up. Put the spudger in the slot and press down and back towards the screen. The keyboard should lift out easily. It doesn’t snap out.
