Remove all screws from the bottom case.
Pry up the bottom case with a pry bar, lift up the bottom case, and remove it.
There are no snaps securing the bottom case, so removing the case is pretty simple.
After removing the bottom case, you can access the battery, speakers, wireless card, hard drive, heat sink, and cooling fan.
Remove the screws securing the battery. Disconnect the battery power cable and two speaker cables.

I can’t open the bottom case, could you give me any help? I removed the screws but the bottom doesn’t go away from the side of the screen. 🙁
You need to use a pry bar to remove the bottom case.
You also have two screws under the rubber feet to the back side.
Hi,
What kind of screwdriver do you use?
Thanks
Tor 5 and Phillips® (cruciform) screwdriver
The plastic hinge anchor under the screen is broken. Any idea on how to repair this?
I had the same problem, and it is a quality issue. I sent it to be repaired, but they could not do it and gave the entire money back for the laptop. It is a beautiful laptop but has terrible quality at the hinge.
Hi, everyone. Have you tried to replace the whole keyboard? If so, can you give me a hint? Because then you open the laptop and disassemble the screws, it is not easy to divide the keyboard from metal.
Currently trying to do the same. Have you found any solution?
EDIT: In fact you can’t. The keyboard is soldered to the case.
if you want to repair your keyboard, you need to buy a whole new palmrest + keyboard
Could someone please let me know what the motherboard model is? Looking at getting a replacement.
Good Question, I’m trying to find out as well. (or an upgrade)
Hello! Can you send me this picture in 4 K (the back of the motherboard)? I would really appreciate it. Thanks.
Sorry! The laptop is no longer in our office.
How do I open the hinge cover to replace the hinge (the silver strip that is still left on when you take off the bottom cover)? The hinge broke, and it’s no longer under warranty.
Thanks. I looked through all the pages, but there are no specific instructions on how to open the small cover over the hinge.
It says “Visit our repair blog to learn how to remove and install the LCD hinge on Asus UX303LN”, but there are no instructions specifically for hinge replacement.
To replace the battery, the hard drive, etc., all you need to do is take off the bottom cover. But for the hinge, even after you take off the bottom cover, there’s still another small cover over the hinge. And this small cover doesn’t have any screws to remove.
It’s quite easy, you just have to move it to the side, and it goes off.
The breaking hinge is an epidemic with this model. Look at the Amazon reviews.
Hello, UX303L’s owners,
There is now an unpleasant mark on the screen.
It is located at approximately the middle of the screen (6,7cm top, 10cm of the edge). It’s 0.5cm high and 9cm width. It’s as if something had worn the screen. This is probably due to friction with the keyboard.
I contacted Asus support but they did not want to know.
Do other persons have the same problem?
Thanks
