The memory chips of the Asus Zenbook UX305FA are soldered onto the motherboard and are covered with a layer of thermal stickers. Since this laptop does not have a spare memory slot, its memory cannot be upgraded.

    1. I found this on a quick search. I haven’t tried it, so I don’t know how good it is or how well it fits.
      Give it a try and post your results, please!

      1. I need to remove the BIOS battery. The laptop won’t power on, and the CMOS reset won’t work, so I wanted to give it a try. I appreciate any help.

  1. Hi, folks,

    I have some questions:
    Can you easily replace the CPU with an i3, i5, or i7?
    Is it easy to upgrade RAM?
    Does it work fully with Linux Distros (Ubuntu/Elementary Freya and Mate)
    If not, what would be the optimal setup? I’m on a MacBook Pro, and I am starting to get fed up with it.

    Thanks
    Ali

  2. How do you remove the LCD cable from the motherboard? Do you just pull up away from the motherboard? Is there a locking mechanism that needs to be disengaged?

  3. My keyboard crapped out, and I can’t seem to fix it. Can you help me find the right replacement part? Thanks!

  4. Is there any disadvantage to not having the cooling sticker on the M. 2 SSD when replacing it? Did someone notice any differences in terms of device temperature?

  5. Hey, two questions
    1. Can I remove the battery and put in a new one (for the future, when the battery loses its power)
    2. Can I upgrade the SSD from 256GB to 512GB? And if it works fine on an i5 model?

      1. Thanks for the reply.
        Forgot to ask what about the keyboard. Can I replace it with a backlit one?

  6. I stupidly dropped a screw on the motherboard when the battery was not disconnected. The motherboard “sparked out” and is destroyed (It’s why I searched your page). Will that also have damaged the battery since it was still live? There are no lights indicating that the battery is connected. And possibly other boards like the USB board? I was hoping to replace the motherboard, but now I may have a total write-off.
    PS: I wish I had found your instructions before I started. They are really excellent!

    1. Hello! Graham, can you please let me know if you’ll ever need to buy a new motherboard? Where do you buy them? I also need to replace the UX305FA motherboard. Thanks!

  7. Thanks for this article!

    If I want to replace the battery, what battery should I use? Can anyone buy the same battery from Asus?

  8. Hi, did you put cooling stickers on the new SSD? Where did you buy them? If not, aren’t you afraid of overheating?

  9. Hi, John, I would like to follow your suggestion to upgrade to this Samsung 500GB. Are there any pitfalls? Is the capacity fully accessible? Can you provide any links for instructions?

    1. Were you able to replace the keyboard? My right arrow key stopped functioning, so I bought a replacement on AliExpress. But I am not sure how to do it. Is there a way to remove the motherboard without removing the SSD, Wi-Fi, or heatsink?

  10. My Asus UX305F would not power up. I tried taking out the battery to use only AC power, but it’s still not working. I tried connecting it to an external display, but I had the same problem. Any suggestions will be greatly appreciated.

  11. Hi,
    I couldn’t understand how to upgrade my RAM. I want to upgrade my 4GB RAM to 8GB RAM. If I buy any DDR3 RAM, can I apply it? Or what is the solution? Since the user guide indicates that you can upgrade from 4GB to 8GB, could someone explain how this is possible?

  12. As far as I know, we can’t replace the CPU, so can we replace the mainboard with another one that has a higher CPU? Can you please point out which one can be used? I don’t want to waste other parts because they are working well!
