Toshiba Tecra A2, Satellite A55 disassembly.

Unlock and remove battery


It's crucial to remove the battery from the notebook before you start disassembly.


Remove card covers


Remove the modem card cover, the hard drive cover, the memory module cover and the wireless card cover from the bottom of the notebook. Each cover is secured by one screw.

Remove HDD, Wi-Fi and memory


Removing the hard drive disk. Slide the hard drive to the left to disconnect it from the connector on the motherboard. After the hard drive is disconnected, lift it up and remove from the bay. If you are replacing the hard drive, you'll have to transfer the caddy to a new drive.
Removing the memory module. Spread the latches on both sides of the memory module until the module pops up. Pull the memory module from the slot.
Removing the wireless card. The Wi-Fi card has two antenna cables connected to it. Each cable has a small round connector (marked with a red circle). The whit cable is main and the black one is auxiliary. You can disconnect the antenna cables with your fingers. After antenna cables are disconnected from the wireless card, spread the latches on both sides of the card and pull the Wi-Fi card from the socket.

Disconnect and remove modem


Pull the wireless card antenna cables from its route. The antenna cables have to be free before you remove the display assembly.
To remove the modem card, remove two screws first. After that carefully lift up the modem card to disconnect it from the motherboard and unplug the cable marked with a red arrow.

Remove CPU cover


The CPU and the heatsink in this model could be easily accessed from the bottom of the notebook. To access them, you'll have to remove the cover first.
Remove two screws securing the cover and lift it up.
Remove CPU heatsink


Remove three screws and remove a metal bracket securing the heatsink.
Lift up the heatsink from the CPU and remove old thermal grease from the heatsink and the CPU. You'll have to apply new layer of thermal grease before you assemble everything back. You can buy thermal grease in any local computer store.
If you need to replace the CPU, you can do it now. I'll remove it at the end of this disassembly guide.

Connectors under the plate are covered with a tape. Remove the tape from the connectors.
Carefully open the keyboard cable connector on the motherboard by moving the lock (brown piece in my case) 2-3 millimeters in the direction shown by the red arrow. After the connector is open, pull the cable and remove the keyboard.

Remove tape


Turn the motherboard over. There would be a tape covering some connectors. Remove the tape.

Unplug all cables


Unplug all cables that marked with a red arrow.
Even though all cables have differently sized connectors, I would recommend to draw a simple diagram (where each cable goes) so you are not confused when you assembled it back.
When all cables are unplugged, you can remove the motherboard and put it on your bench.

Remove notebook CPU


Finally, unlock the CPU socket by turning the screw into "open" position and lift up the CPU. Make sure that you lock the socket when you assemble it back. Also do not forget to apply a thin layer of thermal grease on the CPU surface before you install the heatsink.
If you forget to lock the CPU socket, the laptop will not boot up after you assemble it back.
If you forget to apply new thermal grease, the laptop will overheat and shut down.
