Asus X551C, X551CA, X551M, X551MA
How to disassemble, take apart the laptop if you want to change, upgrade Hard Disk Drive, DDR3 SDRAM, optical drive, remove / replace Battery, Keyboard (KB), Wi-Fi card, BIOS / CMOS Battery, etc.
If your system overheats, you must open the laptop, clean the cooling system and change thermal paste / compound to the processor (CPU).

I have a question, recently I'm having some problems with my Wifi and i did even i could to try to figure out what was going until I open up this latop which is the exact same model. I saw that my Wifi card only has one wire and it came like that from stock and i just don't know what exactly should I do.. I mean I've Althought of throwing it out the window but I just wanted to give this laptop once more chance.
I have an asus x540sa. I removed my battery because it was dead. My problem is every time i plug in my charger it turns on automatically without pressing the power button. What is the problem? Thanks for the answer.
Yes it needs. CMOS is small amount of memory on the motherboardthat stores the BIOS settings like the system time and date as well as hardware settings.
Without CMOS battery your laptop will boots always to default settings.
+ZFix Hi there, can the RAM be upgraded on the Asus X551CA-SX024H at all (and what to)? I presume not, because the RAM is not labeled at any point in the video or in the video description.
And in addition, can the HDD be replaced for a SSD?
Joseph Taylor , I already have a dedicated Linux laptop. I've had to change the operating system on that several times. Between the security issues of Ubuntu, to the instability of Elementary OS, and finally with Fedora but it's not as polished feeling as those other two. This Asus is not my Linux laptop. It's just a solid workhorse.
@3:20 - I noticed that your motherboard doesn't have an expandable RAM slot, it would be left of the 4 soldered RAM chips... specifically, what model do you have!?!?! Because i have one of these (X551CA-RI3N15) being shipped to me and was wondering if I could be able to upgrade the RAM, I've seen some videos where this expansion slot is visible but in this video, it is clearly not there
Yes, no expansion memory slot and the processor is integrated (soldered), this is a low cost laptop.
I found this picture for your model:
If the model is correct, there are not an expansion slot for memory.
Hello, I have an Asus X551CA-SX086H and I'm thinking of upgrading the HDD with the Samsung EVO 850 SSD. I have Windows 10 installed so if I just replace the HDD and reinstall Windows 10 with an USB it'll be activated and fully working, right? Or do I have to change some settings in the BIOS first?
After that I want to use the old HDD for my sister's Lenovo G505 since her HDD broke. We've already sent it to Lenovo to fix it but it broke again after a month. They said they replaced the HDD but I kinda don't believe them. Her laptop also has Windows 10 installed, so do I need to change some settings in the BIOS before reinstalling Windows 10?
Thanks in advance! 😃
Yes, the upgrade process to Windows 10 registers a unique ID associated with your PC’s hardware on Microsoft’s Windows activation servers and whenever you install Windows 10 on that PC, it will automatically from Microsoft’s activation servers. You will lost your license if you change the main board.
For the model in this video - no. There are not expansion memory slot, also the CPU is integrated (soldered) on the main board.
Give me the full model of your laptop, like this: X551CA-RI3N15
This scpecs are for D550CA-RS31:
The Max Supported memory Size is 8 GB
Give me the full model of your laptop.
Thanks for the video. Very well done. May I ask you a question, as it seems you have a lot more knowledge about this topic than me xD. I tried to change the HDD with a SSD. It's shown in the Bios (advanced sata settings or sth like that), but i can't choose it as a booting device. I'm very happy about every hint ;)
Hello ZFix i have the Asus X551C and my problem is the laptop is fully "dead". My charger is ok, when i put the charger in laptop the 2 front indicator lights are not working. I try to put out the battery and i press the power button for 30 seconds, and after put the battery back again, but the problem not resolve. Do you know where is the problem?
+ZFix i tried to switch on the laptop without battery, but the problem still... I tried to take of the CMOS battery and take it back again but nothing...The AC adapter am sure is good because i put it in another laptop and was working good, and i try with other AC adapter but the problem still. The power on indicators on laptop is "dead", its has 2 indicators lights on laptop and the 2 not work... From your experience what do u think about the main board?
Try to switch on the laptop only on charger (without battery). Do you have power on indicator. If no and if you are sure for the AC adapter, the problem is with the charging line or with the main board.
The model of the optical drive is SN-208. Nowadays the optical drives are not used often and there is no statistics which models are better. In your place I would choose a device with a longer warranty.
I may be a bit late but I have a queston. Can I take all the components from this laptop and transfer them to a mini pc case? Like just take the motherboard, processor, ram, hdd, and everything else? Or should I 3d print a custom case or make one with wood and stuff?
+ZFix I could use a usb extender and like run the power cable through a top vent because its skinny. Also since the motherboard has an ethernet port i could remove the wireless adapter from the pci express and use an external pci adapter for a more powerful graphics card.
+Guys Who Do Stuff
Yes, with more skill. You need to think of how to bring out the USB ports, charging connector, optical drive, etc (maybe with expansion cables).
You have to think also for the cooling system. By removing the main board you will break the air streams that pass through the laptop.
I bought a ASUS notebook Model x551M and when I turn it on the mouse works it move around but once I log on and it loads up I'm stuck it want do anything mouse want even move . I've tried to factory reset and it want even do that. Can you please give me some type advice. I called trouble shoot they want to charge me $149.0" take over notebook I only paid $199.00 last week at Wal-Mart
Why they want to charge you? It have to be in warranty?
Connect external mouse, go in device manager and remove the mouse driver or download and install the latest touchpad driver:
If this is a software problem, this will help you. For a hardware problem you need a help from a repair shop.
For the model in the video - no. There are 4GB integrated on the mother board but no slot for extra memory. At 3:18 you can see empty lines for a memory socked but in this board it's not installed.
The problem can be HDD or main board.
The freezing of the laptop can be result of HDD bad sectors, but to be sure, the HDD have to be tested. I told you most likely, because this is very common problem.
Start the laptop in Troubleshoot menu, select Advanced options, then Command prompt and check you HDD with this command:
chkdsk c: /f /r
DVD Writer Model SN-208.
But this is standard SATA, Slim design optical device for laptop.
You have to remove the front bezel and a small metal plate from the back side (for the locking screw) and install them on the new one.
Download the appropriate system image for your device below, then unzip it to a safe directory.
Connect your device to your computer over USB.
Start the device in fastboot mode with one of the following methods:
Using the adb tool: With the device powered on, execute:
Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device.
If necessary, unlock the devices bootloader using one of the following methods:
If you are updating a Nexus or Pixel device that is manufactured in 2015 or later (for example, a Nexus 5X, Nexus 6P, Pixel, Pixel XL, Pixel 2 or Pixel 2 XL device), run this command:
For Pixel 2: To flash the bootloader, Pixel 2s boot loader must be updated to at least Oreo MR1s version first. This may be done by applying an over-the-air (OTA) update, or sideloading a full OTA with the instructions on that page.
For Pixel 2 XL only with loader version prior to TMZ20a: the critical partitions may also need to be unlocked before flashing. The unlock can be performed with this command, and should NOT be done on other devices:
If you are updating an older device, run this command:
The target device will show you a confirmation screen. (This erases all data on the target device.)
See Unlocking the bootloader for more detailed instructions.
Open a terminal and navigate to the unzipped system image directory.
