Today I will disassemble a Toshiba Satellite Radius P55W laptop.
I will show how to access and remove the battery, hard drive, memory, cooling fan, DC jack, keyboard and other internal components.
There are a few different models but the teardown process should be the same or very similar for the following Toshiba Satellite Radius configurations:
- P55W-B5112 (shown in this guide)
For Satellite P55W-C series check out this P55W-C5316 disassembly guide.
Be organized and keep track of screws. We’ll be removing many of them.
Remove all screws from the bottom cover.
There are four screws hidden under two rubber feet.
Carefully separate the rubber foot from the case using needle nose tweezers. Work slowly, it’s easy to break the foot.
Remove hidden screws from both sides.
Separate the bottom cover from the palmrest assembly.
While lifting up the bottom cover pay attention to the power button cable. The cable is still attached to the motherboard.
Turn on the bottom case upside down so you can access the cable connector.
Unlock the connector by lifting up the locking tab. It will open up at a 90 degree angle. Pull the power button cable out.
The power button and volume control board is attached to the bottom cover. It can be easily removed and replaced if necessary.

Remove four screws securing the battery.
Lift up the battery and disconnect the cable. Remove the battery.

Disconnect the hard drive SATA cable from the motherboard.
Remove the hard drive assembly.
If you are replacing the hard drive or upgrading it to a solid state drive, you’ll have to transfer the SATA cable and rubber caddy to the new HDD/SSD.
There are two memory slots on the motherboard.
Standard memory is 8GB but you can upgrade it to 16GB. This laptop uses DDR3 PC3L-12800S 1600MHz RAM modules.
Now we are going to disconnect and remove the cooling module.
Disconnect the video cable. Lift it up by the black tab on the connector.
The video cable routed in the guided path on the side of the cooling fan. Unroute the cable.
Disconnect the second display cable and unroute it too.
Separate the golden foil from the heatsink. Be careful, this foil is attached to the Wi-Fi antenna cable.
Remove two screws securing the cooling fan (yellow circles).
Loosen four screws securing the heatsink (red circles).
Remove the cooling module from the laptop.
Now you can separate the cooling fan from the heatsink and replace it if necessary.
If thermal grease on the heatsink looks dry, you’ll have to apply new thermal grease.

In the next five steps I will show how to access and remove the DC power jack.
Disconnect the USB, SD card, headphone board cable from the motherboard.
Remove two screws securing the board.
Lift up and remove the USB, SD card, headphone jack board.

Remove two screws securing the left hinge bracket.
Lift up the left bracket side so it opens up at a 60 degree angle.
Lift up the DC power jack from the case.
Now you can disconnect the DC jack harness from the motherboard and replace it if necessary.

Disconnect both Wi-Fi antenna cables from the wireless card.
Remove five screws securing the logic board.
Disconnect all cables.
Here’s a closer look at the keyboard cable. On this picture the connector shown in the locked position.
In order to unlock the keyboard connector, slide the locking tab about 2 millimeters to the shown direction.
Do not apply much pressure. The tab must stay attached to the connector base.
On this picture the keyboard connector shown in the unlocked position.
Now you can pull the cable out.
Carefully separate the motherboard from the palmrest assembly.
Remove the motherboard.

Remove four screws securing the speakers.
Move both speakers away from the keyboard.
In Toshiba Satellite Radius P55W laptop the keyboard cannot be replaced without going through all above mentioned teardown steps.
In order to replace the keyboard you’ll have to remove multiple screws securing it to palmrest assembly.

I’m not showing the keyboard replacement but it should be pretty easy if you get to this point.
