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.

  1. First of all remove the battery.
    • First of all remove the battery.

    • like always : draw a map of the laptop and paste/draw where all the screws come from or use a magentic project map.

    • in this step we will show you how to remove the fan and the cooling tubes and pads for cleaning or renewing.

    • there are 8 screws and 1 connector

    • remove the screws ( 1 screw is not on the pictures, you ll find it at the bottom of the fan) but unscrew them simultaneous.

    • remove the connector ( see picture 2 ) using an IC extractor

    • remove the cooling tubes and fan.

    • clean the pads using isopropyl alcohol. you will see pieces (remnants ?) of old thermal paste.

    • if the fan itself is broken , you can replace this by removing the very tiny screws. and remove the black tape.

    • clean CPU and pads with isopropyl alcohol. But, like you know ,be carefull with this.

    • use gloves

    • you can also renew /upgrade the cpu, just use a flathead screwdriver to open the cpu socket.

    • use gloves , cause thermal paste is very toxic.

    • one drop is enough on the CPU , and a little drop on the graphic chip.
