Today I will be taking apart an Acer Aspire E1-531-2438 laptop.
My goal is to access and replace the cooling fan which failed and started making noise. Cleaning the fan didn’t help.
Most likely this guide will fork for other Aspire E1 series models.
Make sure the laptop is turned off before you start taking it apart.
