      1. Why is it that you guys are not able to provide a guide to replace the keypad with that of the G550 JK. Both have exactly the same keypad layout. Only thing I am not sure is the LED arrangement. Not sure about that. Could you also remove the keypad from this and show us how it is made?

            I’m having the same problem. I had it repaired once but yesterday it failed again.

            Do you know where I can buy a replacement? I do not know what to do. I’m thinking of buying a usb to jack adapter…

    Nice guide with photos. My little problem is, far right speaker on my N550JK is not working, I can hear the hissing but no sound from it. Any idea if I can repair it, laptop is still under warranty.

  6. Hi! I was wondering if each individual key on the keyboard is removal because one of my keys is sticky and I was hoping to clean it. Thanks!

    In order to remove the back (bottom) cover, one needs a Torx T5 screwdriver. All the internal screws use a standard (well, smallish) Philips head screwdriver.

    I have an Asus N550Jv and I accidentally spilled some water on the keyboard. 🙁 The motherboard got damaged and I am looking for a replacement. I have a question for you, do you know if the mobos of the N550 series laptop are all the same?

    Thanks in advance.

      1. Hi David, What is the use of the heat sticker? Is it supposed to be a heat sink (to distribute heat across all the chips) or a heat shield (block the heat like those used under the keyboard).

        Should naked memory chips be better for heat dissipation? Thanks.

  12. Thanks for this disassembly guide!
    As with a few other users, my Audio jack socket has broken and it looks like I have to replace the whole mobo. Will a replacement motherboard(same one exactly) work or will there be issues with components not recognising (or accepting) the new mobo? ie I keep all the old components(wifi, cpu, heakers, ram etc) and simply move them to the new motherboard?


      1. Looking at it looks like I either need to replace the whole motherboard or just the audio jack as you just said. If I replace the audio jack, I would need to to solder it onto the board; How delicate is the board when it comes to soldering on to it? Any tips?

        Thanks again
