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)
• P55W-B5162SM
• P55W-B5181SM
• P55W-B5201SL
• P55W-B5220
• P55W-B5224
• P55W-B5260SM
• P55W-B5318
• P55W-B5318D
• P55W-B5380SM

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.

STEP 1.

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.

STEP 2.

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.

STEP 3.

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.

STEP 4.

Remove four screws securing the battery.

STEP 5.

Lift up the battery and disconnect the cable. Remove the battery.

Replacement battery model PA5189U-1BRS.

STEP 6.

Disconnect the hard drive SATA cable from the motherboard.

STEP 7.

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.

Upgrading this regular 2.5″ hard drive to 2.5″ SATA solid state drive will improve laptop performance significantly.

STEP 8.

There are two memory slots on the motherboard.

Standard memory is 8GB (2x4GB) but you can upgrade it to 16GB (2x8GB).  This laptop uses DDR3-12800 1600MHz RAM modules.

Now we are going to disconnect and remove the cooling module.

STEP 9.

Disconnect the video cable. Lift it up by the black tab on the connector.

STEP 10.

The video cable routed in the guided path on the side of the cooling fan. Unroute the cable.

STEP 11.

Disconnect the second display cable and unroute it too.

STEP 12.

Separate the golden foil from the heatsink. Be careful, this foil is attached to the Wi-Fi antenna cable.

STEP 13.

Remove two screws securing the cooling fan (yellow circles).

Loosen four screws securing the heatsink (red circles).

STEP 14.

Remove the cooling module from the laptop.

STEP 15.

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.

STEP 16.

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.

STEP 17.

Lift up and remove the USB, SD card, headphone jack board.

STEP 18.

Remove two screws securing the left hinge bracket.

STEP 19.

Lift up the left bracket side so it opens up at a 60 degree angle.

STEP 20.

Lift up the DC power jack from the case.

STEP 21.

Now you can disconnect the DC jack harness from the motherboard and replace it if necessary.

STEP 22.

Disconnect both Wi-Fi antenna cables from the wireless card.

STEP 23.

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.

STEP 24.

Carefully separate the motherboard from the palmrest assembly.

STEP 25.

Remove the motherboard.

STEP 26.

Remove four screws securing the speakers.

STEP 27.

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.

For the display panel disassembly instructions please follow this Toshiba Satellite Radius P55W LCD screen replacement guide.

In this guide I explain how to clean the cooling fan in a Toshiba Satellite P305D laptop. Also this guide should work for the following Toshiba models: Satellite P300, Satellite P300D, Satellite P305.

My customer complained that his computer overheats and shuts off while running a game. Apparently, the heat sink got clogged with dust and needed a good cleaning.

There is no easy access to the cooling fan in a Satellite P305D. You can see the fan grill on the bottom but the fan is covered with a perforated metal sheet.

Blowing air into the grill will not be enough for cleaning the cooling module.

You can get better access to the fan under the keyboard. Let’s remove the keyboard.

Remove three screws located in the battery compartment.

Carefully lift up and remove the keyboard bezel.

Remove two screws securing the keyboard.

Lift up the keyboard and place it upside down on the palm rest. It’s not necessary to disconnect the keyboard cable from the motherboard.

The cooling fan is still covered  but at least now you can blow air into the fan and remove all dust from the cooling module.

First. Blow air into the cooling fan through two holes on the top cover.
Second. Change the direction and blow air into the fan grill on the side. Also, blow air into the air intake on the bottom.

Change air direction two-three times until there is no dust coming out of the laptop.
