Taking apart Samsung 900X notebook

posted in: 9. Other Brands | 35



In this guide I’ll be taking apart a Samsung 900X notebook. I’m working on notebook model NP900X3A.

Most important components in a Samsung 900X notebook located under the bottom cover.

I’ll show how to remove the bottom cover and access the internal notebook components.

Before you start, make sure the laptop is turned off.

STEP 1.

Some screws securing the bottom cover are hidden under the rubber feet (red circles) and rubber covers (yellow circles).

The rubber feet are glued to the bottom cover with double sticky tape.

STEP 2.

Using a sharp object carefully lift up the rubber feet and unglue it from the bottom cover.

STEP 3.

Remove four screw covers.

STEP 4.

Now remove all screws securing the bottom cover.

STEP 5.

Start separating the bottom cover from the notebook.

STEP 6.

Lift up and remove the cover.

Now you should be able to access most major notebook components. Let’s look at them one by one.

The notebook battery secured on the bottom and connected to the motherboard via a cable.

Do not forget to unplug the battery from the motherboard before you start removing other laptop components.

The hard drive is mounted in the upper left corner.

Samsung 900X comes with a 1.8″ SATA SSD.

In my notebook I had a 256GB SSD installed.

The cooling fan doesn’t have the cover.

It’s very easy to remove and replace the cooling fan in this notebook.

All you have to do is remove two screws and disconnect the fan cable from the motherboard.

The wireless card mounted right above the battery.

Samsung 900X notebook has two memory slots. You can use DDR3 memory only.

The CMOS battery is not soldered to the motherboard. It can be unplugged and replaced.

The DC power jack is located in the upper right corner.

The DC jack attached to the cable which can be unplugged from the motherboard. If the DC jack fails, you have to disconnect the failed DC jack harness and replace it with a new one.

The DC jack is secured in place by the mounting bracket and one screw.

  1. I’ve got red yellow and blue pixels appearing on the screen of my 900X. They are always there and seem to be slowly multiplying.
    Any ideas on what the cause is?

    @ Dipak,

    I’ve got red yellow and blue pixels appearing on the screen of my 900X. They are always there and seem to be slowly multiplying.
    Any ideas on what the cause is?

    Can you test the laptop with an external monitor? Do you have the same problem with external video or it appears only on the laptop screen?

  3. Hi IML Tech,

    My Samsung 900X1A screen is a bit loose and it wobbles a bit every time I open up the lid. Am I able to find the hinges to tighten the screen if I open up the back casing of my laptop according to your instructions here?

    Regards,
    Bale

  4. Thanks for all the helpful stuff – I fixed an overheating CQ50 following your guide.
    With this one is removing the keyboard easy after doing the above.?

    Hi Rustymind

    I’ve got a Samsung 900X1A-A01US Laptop with a broken screen. I’ll be notified as soon laptopscreen.com has the compatible screen on stock, after that i’ll publish a video on youtube for replacing it. I’ve opened it so far, the screen is very tricky. If you can afford the 350 USD for the whole screen instead of only the panel, it’s very easy to install.

    I’ll update a newer video to my youtube channel (search for “Scaboful”). Hope this helps.

    Hi , I have a different problem.. Any ideas? Really appreciated..
    My Samsung 900x1A is really nice, but it is very hard to use wirelessly…
    It picks up only 1bar, whereas smaller samsungs (e.g 110, etc. ) have 4 bars from my router…
    I tried replacing the wireless adapter i think it was (like a micro ssd size thingy inside but it
    didnt help..) Any ideas of things i can try?

    Thx, ken

    Will this give me access to clean the keyboard too? My son splashed oj on my laptop and while it works fine, the keys are terribly sticky.

    I think it will be necessary to replace the keyboard.
    Unfortunately, this guide will not allow you to replace the keyboard. In order to replace it you’ll have to disassemble the entire laptop and remove the motherboard.

  10. Hi there, I just wanted to say thanks you are awesome my Series 9 had a faulty DC jack i am about to replace it myself do i need to solder anything? since i have no idea how to solder…
    Do you know where to buy a new battery for this ultrabook? Thanks for all your help you are a lifesaver

  11. IML Tech

    @ Sal,

    my Series 9 had a faulty DC jack i am about to replace it myself do i need to solder anything?

    Is it same laptop as shown in my guide?
    You don’t have to solder anything. The DC jack attached to the power harness and can be unplugged from the motherboard. You can find a new DC jack on eBay. I posted a link in my guide, it’s above the last picture.
    In order to replace the jack you’ll have to remove the bottom cover from the laptop, unplug the old jack and replace it with a new one.

    Do you know where to buy a new battery for this ultrabook?

    A new battery also should be available on eBay.

  13. Hi

    I have samsung 900x i7 full HD and it is too hot when processor is on 15% , It is so hot that I can’t even tuch it from the bottom . Is this OK?

    @ Lubo,

    I have samsung 900x i7 full HD and it is too hot when processor is on 15% , It is so hot that I can’t even tuch it from the bottom . Is this OK?

    No, it’s not OK.
    You can remove the bottom cover and take a closer look at the fan and heatsink. If the cooling module clogged with dust, cleaning might helps.

  15. My Samsung 900Xc notebook keyboard is totally not working. The rest of the laptop is working. How do I check the keyboard internally. Maybe the glass of wine my daughter spilled on it in Africa is the cause. Thanks

    @ Des,

    How do I check the keyboard internally. Maybe the glass of wine my daughter spilled on it in Africa is the cause.

    You can test the laptop with an external USB keyboard. If everything works fine, apparenlty only the laptop keyboard was damaged.

  17. Hi There,

    Hi, I face a problem with my 900x that I havent´t seen before; my girlfriend tried to install WiN 8.1, didn´t work and afterwards we tried to use F4 (recovery) to set back to the original status of software – didn´t work out. in boo modus it is looping, F2 to boot menue is not accessible and F4 is going back to restart. Message on screen shows: “All boot options are tried Press F4 key to recover with factory image using Recovery or any other keys for next boot loop iteration.” => any key brings me back to this message and F4 just doesn´t work. Do you have any idea´s ???

  23. IML Tech

    @ Steve,
    Did you try to install Win 8.1 from a CD? Maybe she reformatted the drive and erased the recovery partition?

    Hello,

    Know this was done along time ago but I don’t suppose you know what cable was used for the normal sata connection. Wants to change mine from mSATA to 2.5 SATA

  31. Hi I love my NP900X4C-A05AU with a 256G SSD. What is the biggest SSD drive that I can replace it with and what model would fit inside. Thanks for your site.

  32. I have a 900x with a 128SSD – mSATA version. On amazon you can get up to 512GB if you want to DIY Upgrade. If yours came with a 1.8″ SATA SSD you must continue to use the same 1.8″ SSD, they also have 512GB storage capacity.

  33. What type of screwdriver do you need to take the screws holding the keyboard in place? These screws are smaller than outer screws. I bought two sets so far and none fits. Thank you

  34. I broke my screen and need to replace it. I try to buy one on Ebay but I need the proper reference: I have a notebook 900X model NP900X4D. What is my screen’s reference?? Tks
