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.
New cooling fans for Samsung 900X notebooks available here.
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.

@ Sal,
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.
A new battery also should be available on eBay.

@ Kristin,
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.

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.

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

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.

How do you get into the lcd assembly to replace a broken screen?

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 Laptop 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
