    @ ken Lizotte,

    @ 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.

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

  5. 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.

  6. Ruth

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

  7. 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.

    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.
    Regards

    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.
