Hey all,

Today I will show you how to open the Toshiba satellite C55-A5285/C55-A1J2. It is the same same computer inside and you will see how to remove/replace different parts of the laptop and repair it. Or you can upgrade the laptop.

In this project I had to clean out ( dust and others) the inside of the laptop. But I will show you the rest as well.

This will work on a Toshiba made for the American market as well as the one for the European market as well. Both the C55-A5285 and the A1J2 are both same on the inside.
