    Thanks for detailed guide. I own same laptop and keyboard for this has gone bad. Do you have any idea if keyboard is also removable ?

    @ Jarvis,
    The keyboard is permanently attached to the top case. In order to remove the keyboard you will have to remove the metal plate covering it. The metal plate is riveted to the top case.
    It’s doable but not easy.

    Hi. I have this model laptop and it’s not turning on. No lights, no sounds, not even with AC adapter plugged in.

    The last thing I did may be responsible. I attached two mobile phone auxiliary charging devices to USB ports to get charged. Perhaps laptop went into sleep mode and those devices sucked up all battery power. But not sure why connecting AC power not working either.

    Steps so far:
    Pressed power button for few seconds to over a minute for a hard shut down. no response
    I checked AC adapter, it’s working fine with another laptop.
    I tried Windows+B+power button a few times. no response
    I tried Windows+V+power button a few times. no response

    If you can please help solve, I will make a donation. Thanks.

      Sounds like a power related issue. Here’s what I would try.
      1. Remove the bottom cover and disconnect the battery cable from the motherboard as it shown in the step 4. Plug in the AC adapter and see if you get any response with the battery unplugged.
      2. Check voltage at the connector where the DC jack plugs in into the motherboard. Make sure the voltage travels from the AC adapter to the motherboard. It’s possible you DC jack is bad.

    I tried #1, disconnecting battery cable from motherboard and laptop is working again! Thank you! So now, do I need to install a new battery or can I power up the existing one somehow? If I have to install a new one, can you please recommend an inexpensive but reliable place to get one?

    • IML Tech

      I don’t know the condition of your battery but I would definitely try the existing one. I’ve fixed many laptops simply by reconnecting the main battery. Hopefully it works for you. If you decide to go with a new battery, I would strongly advise buying a genuine HP battery instead of third-party replacements. You should be able to find a new battery using the HP part number from the original one.
      Probably it’s same battery LP03XL. Available on eBay for about $30.

    Thank you again — the battery worked after reconnecting!
    Really appreciate all the guidance.

    Hi, I am curious, where did you get that skin? It looks nice and my laptops silver/chrome like color is wearing out by my wrists and looking really bad. Anyway, I used this, it was great! You’re the only person that has instructions on opening up this model! You’re awesome.

    • IML Tech

      @ Judy, this is my client’s computer. I’m not sure where where he bough it but it looks like there are many different options on the internet.

    IML Tech,

    I’m thinking about cleaning my fan as I’ve seen on other videos with other laptops. Although, this model, it seems (according to your pics) that the fan is incased in some plastic holder. The videos I’ve watched the people have used quetips with alcohol to clean the fan. This doesn’t seem easy with this fan. Or do you think it opens as well? Or is it just one unit, and I’m just stuck with it as it is and the best way is just using condensed air (even though I tried that and it didn’t improve much).

    • IML Tech

      Judy, it looks like the cooling fan and heatsink is one unit and doesn’t open easily.
      Here’s what I suggest. Buy a can of compressed air or use an air-compressor. Spray air inside the fan until all dust is gone. This should be enough to remove most of the dust.
      I think cleaning the fan with Q-tips and alcohol is an overkill.

    To replace the palmrest/keyboard assembly, do I have to follow your disassembly guide starting from the bottom and removing everything as shown here, or is there a way to simply remove the palmrest/keyboard assembly from the top and replace it? I didn’t see where you removed the top, everything seemed to be removed from the bottom and then you got to the keyboard, a bit confused. Also it’s only my “T” key this isn’t very responsive, all my other keys work fine.
