Introdução
If you are having issues with your touchpad, the error may be in the touchpad button board. This component can be found below the battery, hence that guide is a prerequisite to this workflow. Once you have removed the battery from your laptop, you may follow this guide to remove and replace the touchpad button board.
The button board is the "brains" of the touchpad on your laptop. The touchpad itself is just a special, thinner piece of plastic, held in place by permanent plastic rivets, meaning it will take other specialized tools to remove. If this part is damaged on your laptop, it will take much more work to replace.
