    Thanks a lot!
    Some days ago I needed to dissassemble my laptop and the official manual was not enough to guide me. When I tried to assemble my lapto again, it didn’t turned on. Your site rescued me and helped me to connect all the wires. Now I am writing this comment from my laptop.

    An excellent guide. In fact these guides would help any interested person judging the build quality before buying or indeed recommending to others whether to buy. My main issue is ease of access to RAM, HDD and power inlet socket. Much better if the latter is NOT soldered to the mobo as in this model.
    Keep up the good work. Thank you.

    I want to get to the hinges of this model as they are clicking/stiff. I may need to replace them. What dismantling methods are recommended? I am thinking I proceed to step 20 of this disassembly guide then can gain access to the hinges. Is that correct or is there more to repairing/replacing the hinges than I am thinking? Further guidance will be appreciated. Thanks.

    i recently disassembled my laptop hp 15 n series, but during reassembling process i was unable to fix keyboard in its adapter on motherboard, as a result the adapter on motherboard in which the keyboard strip gets fixed was completely removed from motherboard. So nw i have to replace the whole motherboard. PLease tell me if there is some other solution without changing the motherboard.

    thank u

    Great guide! Can you tell me what type and size of screwdriver I need for the optical drive bay screws? (Step 16)

    Is it Philips or JIS? And what size?

    • Pascor

      These 3 optical drive bay screws require a PH00 (Phillips Head #00) screwdriver if those screws are difficult to remove. Otherwise, you might try using the largest flat blade “jewelers”
      screwdriver that will will still fit within one leg of the “X” on the screw head.

      All other case and motherboard screws can be removed with a PH1 screwdriver.

    Very nice tutorial, have dis- and re-assembled the laptop twice already using it. But after having done the first time (and since then) the power button has no working light in it (despite the connected ribbon), and the screen does not sense when it is closed, so always stays on. What might be causing this?

    Also: the whole reason I had to take it apart is because the cooling fan was rattling. Now the new replacement is also giving off a faint rattle (at high RPM, or if the laptop is tilted). Does any one of you also have a problem like this?

    Hello, i couldnt complete step 16 for my hp pavilion 15 laptop, how and what can i do? the screw is so tight and none of the screw driver head works

  10. Jessica

    I’m having the sane problem as Teo. I’ve got a jewellers screwdriver and pliers to help me twist it but all I’m finding is some give in the screwdriver that shouldn’t be there, it’s a disaster!
