Toshiba Satellite Radius P55W disassembly guide

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

Be organized and keep track of screws. We’ll be removing many of them.

Keep track of removed screws

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.

Standard memory is 8GB but you can upgrade it to 16GB.  This laptop uses DDR3 PC3L-12800S 1600MHz RAM modules.

    Can I replace failed fan without removing the heatsink?

  2. IML Tech

    Chris, I would suggest removing the heatsink because the fan has an adhesive tape which is glued to the heatsink on the bottom. It will be much easier to replace the fan when the heatsink is removed.

  3. Joseph

    This explanation is awesome, thank you. Would you also have an exploded parts list? I am looking for the DC jack harness that is shown in step 21. Thank you

  4. IML Tech

    @ Joseph,
    Go to eBay and type: Satellite Radius P55W DC jack. You will find it. The jack is $7 with free shipping.

  5. Michael

    I’m in the process of trying this and the screw in the middle will simply not budge. Did you also run into this? All the other ones came out fairly easily, this one however will not and I’m not able to continue without it coming out. Thanks!

    i want to buy only speaker part , please help me how can i buy online that spare part
    can it replace without separate motherboard screw , also suggest for me which one speaker is the best for high definition sound, i am waiting for you for your response

  7. IML Tech

    @ janson,
    You can find spare speakers on eBay. Just search for “Satellite P55W speakers”. You will see them listed for sale for about $10.
    In order to replace speakers you will have to remove the motherboard because the speaker cable is routed under the motherboard.
    All speakers for Satellite P55W are similar. There are no special high definition speakers.
