Asus Zenbook UX431FN: Display glitches when adjusting the screen (to close or open)

Mon, 01 Dec 2025 09:47:31 -0700

Whenever I adjust the stance of my laptop screen it glitches. At some position the display is completely black. With a small adjustment the display returns. I am afraid that in a while the screen won't return. My guess is that the hinge between the display screen and main body of the laptop is broken. How could I fix this?

Asus Zenbook UX431FN: Did I break my keyboard or my motherboard?

Wed, 15 Jan 2025 10:46:30 -0700

The model I have is slightly different from the one in the title, it is a Zenbook UX433F, although I think the only difference is the color (mine is blue).

I was cleaning and repasting it, following a couple of youtube tutorials, none of which showed that you need to unclasp the keyboard connector before unplugging the ribbon cable. So, I just pulled it out without unclasping it.

After reassembling it, the keyboard was actually working okay for a few hours before certain keys stopped working. In my infinite wisdom, I thought that I just didn't reconnect it well, so I actually forcibly pulled it out and re-connected it AGAIN without releasing the security latch.

In my defense, I couldn't find any kind of official disassembly manual. Lesson learned.

At this point around 20-30% of keys aren't being detected (I can list them out if necessary). If I push the cable at certain angles, I can get some keys to start working, but not all of them, and there doesn't seem to be any reason behind which angle activates which key.

I'm thinking of just replacing the entire keyboard at this point, but I'm also afraid if I actually broke the connector on the motherboard, and not the ribbon cable.

So, is there any way for me to check if I broke the keyboard or the motherboard connector, without buying a new keyboard?

Asus Zenbook UX431FN: How to fix my audio jack?

Sat, 07 Oct 2023 21:40:43 -0700

I accidentally pulled out my earphone at an angle and when I tried to put them back in the audio jack, it won't play any music. I think it should be the audio jack as the other earphones also don't work on it while when I plugged my earphones to another device, they work.

Asus Zenbook UX431FN: Why does my screen display only white noise?

Sun, 09 Jul 2023 01:37:30 -0700

I opened my Asus Zenbook laptop the other morning, and the display only shows white noise. I tried all kinds of different keyboard startup combinations, removing the battery etc, but nothing seems to work. The computer only starts up and diplays white noise. When I long press the power button, the fan starts making a loud sound. What could be the problem? Thanks for all the help.

Asus Zenbook UX431FN: Blinking Display Screen while using WEBCAM

Wed, 29 Apr 2020 06:33:21 -0700

Before we start:

1) My questions and specs are at the end

2) My video and webcam drivers are updated

- Nvidia video card - https://i.imgur.com/kUVs0hP.png

- INTEL video card - https://i.imgur.com/ZsNFoC7.png

- Webcam - https://i.imgur.com/UYtFIgq.png

==================

I have been using webcam a LOT in this quarantine for video calls. I use two types of webcams:

1) Laptop built-in camera ( Hardware ID https://share.getcloudapp.com/nOu8lbN1 ) OR

2) My brand new external Logitech BRIO webcam

ISSUE:

Whenever I use either of the two webcams, the issue is the same - my screen keeps blinking immediately after starting the video call and after about 30 to 40 minutes into the videocall, it freezes my screen. The moment I pause the video OR disconnect the external webcam, the computer is back to normal.

What is odd is that other than using webcam, computer runs really fast, even on hard tasks like editing video on camtasia, for example. (See Specs below).

IMPORTANT to say that the issue happens either if i’m using the laptop screen directly OR if I’m using external monitors connected via HDMI (Tried 2 monitors. They work fine).

## QUESTIONS:

1) Is it my machine or have you guys had this problem also with the same model or similar models?

2) Could it be the video board?
