If you are going to replace it with another hard drive or SSD, you will have to transfer the mounting bracket and the SATA cable.

In HP 15 notebook PCs the keyboard is permanently attached to the top case with rivets.

When the keyboard fails, it’s necessary to replace the top case or try this repair hack.

The touchpad is glued to the top case but the touchpad button board can be removed.

HP 15 notebook PC LCD screen removal.

This part of the disassembly guide is independent from the first part. You can disassemble the display without going through all previous steps but don’t forget to disconnect the battery before you start.

Start separating the display bezel from the back cover. You’ll have to wiggle the bezel to unfasten it from the cover. Start on the top and move to the sides fo the display assembly.

On the bottom the bezel is attached to the LCD screen with adhesive tape. Carefully separate it from the screen.

    Post a guide for disassembly of the HP series notebooks that include HP 17-BS061ST and you will get a donation from me.

      @ ken Lizotte,
      I’ll do the guide as soon this laptop for repair. Check out the official service manual for disassembly instructions.

  2. IML Tech

    @ Ashish,
    I’m not sure if I understood your question correctly.
    The laptop display (I guess you call it top case) is screwed to the palmrest. You can see it in the step 13.

  3. Ruth

    could I do this to clean the laptop fan, or should I get it done professionally?

  4. IML Tech

    @ Ruth,
    Buy a can of compressed air (or use air compressor) and spray air into the fan grill on the side. This should be enough to clean up the fan.

  5. Ruth

    I already did, sprayed into the fan until the bottle was almost empty, but still the loud noises continue…

  6. IML Tech

    @ Ruth,
    It’s possible the cooling fan makes noise because the bearing has failed. In this case cleaning the fan will not help and it has to be replaced.
    Replacing the fan is relatively easy.
    1. Remove the bottom case as it shown in the steps 1-3.
    2. Remove and replace the fan as it shown in the steps 10-11.
    A new replacement fan can be purchased from eBay.

  7. Ruth

    I decided to open the laptop and see for myself and turns out you’re right, I cleaned the fan but that didn’t help at all with the noise. I’ll try to purchase a new fan as soon as possible, thank you for your help! 🙂

    Hi, how easy is it to replace the back cover on one of these things? I’ve seen an ad for a HP 15 at a reasonable price but it has damage to the back cover (the bit that the screen is mounted on) and wondered whether it was worth getting and replacing the cover.
    I have a HP 15 myself for my main PC and they’re nice PCs.

  9. Austin

    Is it possible to replace individual keys that have stopped working? The right half of my space bar doesn’t respond while the left half works fine.

  10. Dan

    Do i understand correctly that you have to do ALL 18 steps just to get to the keyboard and replace?

    • IML Tech

      @ Dan,
      You are correct. The keyboard is mounted to the top case under other components. You’ll have to disassemble it completely if you want to attempt keyboard replacement.

  11. Alex

    So, I can’t just replace my keyboard, I have to buy a whole new section of the case? Also, do I need to remove the display in order to replace the top case?

    • IML Tech

      So, I can’t just replace my keyboard, I have to buy a whole new section of the case?

      That’s correct. The keyboard is permanently attached (riveted) to the top case.

      Also, do I need to remove the display in order to replace the top case?

      Yes. The display is attached to the top case. You have to disassemble the entire laptop in order to replace the top case with keyboard.

      • Alex

        I have to ask how would I remove the case around the monitor? I can find information on how to remove the monitor from it’s casing, as shown here, but have yet to find anything on separating the top case from the monitor casing.

        • IML Tech

          You have to disassemble the laptop as it shown here. When you are at the step 18, you remove two screws from the display hinge shown on the left. Lift up the hinge and separate the top case from the display assembly.

    I trashed the board side HD connector (JHDD) any idea where I can get this 8 pin board level molex connector?

  13. gabriyl

    please I have hp notebook 15 dy0013dx…which came in without a hard drive connector…I have plan on getting it from a shop or ordering for it from abroad…buh I simple don’t know which type is compatible with for my notebook laptop…is there anyway anyone one could help me,,,??

    • IML Tech

      It looks like HP Notebook 15-dy0013dx can support two types of drives – a regular 2.5″ HDD and a solid state drive PCIe, NVMe.
      Here are part numbers for the connector boards for both drives (found in the service manual):

      (5) Hard drive bracket L20455-001
      (6) Hard drive connector board L20454-001
      (7) Hard drive/solid-state drive cable L20456-001
      (8) Solid-state drive bracket L20458-001
      (9) Solid-state drive connector board L20457-001

  14. Melissa

    Thank you! I was able to diagnose and fix my laptop with your help. It was a loose video cable behind the screen! The complete disassembly you did was extremely valuable. It is the only one I was able to find that actually aligned with the model laptop I had.

  15. Gary M Balanesi

    I have a HP 15 db 0043nr that has no Cd rom/ dvd writer. I ordered a proper
    Drive for the model, even the texture is the same on the case. Im
    wondering if i can order a lower case bottom that has the cd rom cutout in it.
    So i can use it.

  16. nick

    is it possible to change the processor in the laptop which is shown in the images?also can you mention the motherboard model name.Thank you!

    • IML Tech

      No, you cannot change the processor because it’s soldered to the motherboard. If you need a faster processor you’ll have to replace the motherboard. You can find a list of different motherboards in the service manual. The link is at the end of the disassembly guide. For Intel motherboards the list of part numbers located on the page 73.

  17. Terry

    OK, I’m having quite the trouble figuring out how to route the display cable, wifi adapter lead, etc. through and around the hinge, while trying to get the bezel and bottom case back on. Is there any way you could show this procedure?
