Hi, my laptop is ASUS UX31A TOUCH.

When I was updating bios, power is dropped, and then, laptop can not be booted.
The keyboard's light turns on, but the screen remains dark.

So, I bought CH341A and could save my brocken bios file.
However I could not open that file with FD44Editor_0.9.2, It just shows below fatal error.

--------------------------------------------------
error parsing bios data

bootefi signature not found.

please open correct ASUS BIOS file.
--------------------------------------------------

After all, I could not confirm the information of it or modify bios rom file.
What can I do?

Can someone please help me?
I need this laptop for study.

Please help me. Please~!

I uploaded my broken bios -> damaged ux31a touch bios.bin
This is BIOS FILE from the ASUS homepage. -> UX31AAS.216

Can someone please help me? I need this laptop computer for my college study. I only have this one, so I am really in trouble.

Please give me some advice.

I will try to reconstruct a valid bios file for you mate, but you need to wait few hours as I'm working now but
I promise that I will attach a new valid bios file in the afternoon (7:21 a.m. here).

Thank you. It's OK. I'm going to wait.

Hi, here is your fixed (I hope it) bios.

Let me know if it works, if doesn't I'll try a different way.

I tested it, it works. But the keyboard does not light up.

Would you please try it again? I am sorry.

I have a bios file of ux31a but not touch version too. If you need it, I can upload it.

@Kanaria

I've uploaded a new fix, download at the same post of the previous bios file.

<Need help> to fix the bios ROM file for ASUS ux31a touch

Thank you so much, but it does not work at all.

First one you uploaded worked, but the keyboard didn't light up.

Second one you uploaded didn't work at all.


Would you please retry it?

I uploaded working bios file which is ux31a non touch above(I got it by internet searching).

I am so sorry to ask for troublesome things

I can't understand if you need a non touch bios or the touch one.

Anyway did you try to follow these guide ?

Try this new one fixed asus bios file. Now keyboard should work fine.

Is Touch BIOS different from non-touch BIOS? I thought that was the same.

The BIOS you first uploaded worked but the light on the keyboard did not light up.

I really appreciate what you did for me.

Thank you. I will try it and tell you.

Try the "asus_fixed" I linked before.

Thank you for linking the video.
I already know about that.
The content of that movie is about ATKPackage? I think it's a problem with the driver after booting the windows.

I tried new bios which you uploaded, but the keyboard light didn't turn on.
Previously, as soon as I pushed the power button, I got the keyboard light.
but now, I don't get the keyboard light when I push the power botton, and after the boot of Windows, the keyboard light does not work, too.(I've already set up the ATKPackage.)

I think that touch BIOS and non-touch BIOS are the same, so can you try again with a non-touch BIOS that works normally?

I really sorry that I bothered so many times. T.T

Try this new one please (I've used the no touch settings but it should work like a touch).

I changed the BIOS to this file., but still the light of the keyboard did not light up.

Maybe, I have to be satisfied with the fact that the laptop has started to work.

I truly appreciate from the heart that you took time to do it for me so many times.

I think you are a really nice person.

Thank you very much.

Than you!!

Did you read this entire video ? It seems like your issue.
