Weird keyboard issues

Keyboard is "eating" random characters on my Asus N750JV when I type. For example, while I type fast, every few words there is a character missing in a word (for example "wrd" instead word). I tryed to press the keys stronger but no help. It seems like a software issue since it can happen on any key (including space, numbers etc.) so it's not a broken key.

It's really frustrating since I'm typing pretty fast and this is slowing me down a lot. How to fix that? Some keyboard driver update? BIOS update? Windows problem? Does somebody have or had the same issue?

Thanks

 

That's the infamous missing keystrokes by Asus. I dunno if it is software related that can be fix by updating the bios or a hardware one.

 

Thank you for telling me the name of the issue. I didn't know what to write so I didn't find anything by googling. Now I see that I'm not the only one. I tried to update BIOS and I got this: https://db.tt/E0yWbc6h I found my BIOS file here: http://www.asus.com/Notebooks_Ultrabooks/N750JK/HelpDesk_Download/

Does that mean that I already have the newest BIOS? I'll try to delete Asus's touchpad utilities and some other things and see it if helps.

EDIT: I removed ATK ACPI package and it works fine so far. I managed to write a few hundred charachters without a single missing keystroke. I will see will it remain like this after more usage. But what does ATK serve for? I read thatit makes the OS communicate with BIOS. Is it possible that I will lose something now? I also read it does some kind of power management. I will have to test if it affects my battery life, because this notebook has a great battery life. But I still have Power4Gear installed so I hope there will be no problems with power management. My FN keys (for skipping songs, for calculator, volume etc.) are still working as well.

EDIT: nope, the problem is still there.

PS. how to edit which app is opened when I press that auxiliary button (the same one as power button but on another side)?

 

The issue you're describing with the keyboard sounds like ghosting. The severity or presence of it is inherent in a lot of keyboards across several manufacturers. Unfortunately it's not something you can patch with a BIOS update, as the problem lies in the keyboard specifically.

 

Seems that you're right. I tried the keyboard tester provided on the link you gave me and double presses mostly work, but some triple presses doesn't work. For example, when I hold G and H pressed, if I press R, T, Z or U, it doesn't detect it. But if I press any other key, it works. But how is it possible that while typing text I press 3 keys at once? I think it's impossible because I use only 3-4 fingers to tipe.

And, if you said that most keyboards have this deffect, how is it possible that I never noticed anything similar on my other devices? I had my previous laptop for 5 years and I wrote millions of words on it and it never ever missed a single keystroke.

So I still think that ghosting is not the issue in my case. I do believe that it's an Asus's fail in drivers or something. Now it works fine again. After uninstalling ATK, it works a little better. It misses a keystroke once in a while but much less than before. I tried to type a longer text in Word to try to find some on which keys it fails but it didn't failed not even once. And while I'm typing this post, it works as well.

But whether it's ghosting or something other, we musn't forgot the fact that this is not a 200$ cheap laptop! I paid a lot for it, and everything has to work perfectly! I wont tollerate bugs like this, this laptop can't afford itself such mistakes! I have to fix this as soon as possible since I'll soon have to start typing some important documents.

 

It very well could have been driver related. Have you installed the keyboard filter and latest ATKACPI package for your model?

 

Rollover is not really a well known issue and for power and simplicitys sake designs are kept simple so are more susceptible to it.

 

I installed everything from a CD that came with my laptop. Actually, it did everything by itself. I wanted to try to download and install latest drivers from website but I done something similar with audio drivers (firstly I installed the one from website and then the one from CD) and I have some problems with audio as well, but they're not crucial (if I use MaxxAudio, after some time of silence, the sound gets very quiet so I have to turn off and again on MaxxAudio). Should I just download newest drivers and install them over these from CD or should I first remove those already installed?

Everything is OK if the end users won't notice any difference. When users start noticing some deffects, this is not a simplicity design anymore, then it becomes A BUG! As I said, my old laptop didn't have this issue. I don't know what design it used but if it can work on this laptop as well.

Interesting fact, it occured a few times while I was writing this post. The difference is that now I'm listening to music and using MaxxAudio. So, before I was typing my previous post, without music and it worked fine. Now I started my music, sound was very quiet so I turned off maxxaudio and turned it on again to make it louder. Then I started typing this post and it occured at least 7-8 times.

I started suspecting that the audio driver is the main problem.

 

It could be a resource sharing conflicts with the irqs.

 

Probably. Oh, seems that there's no other solution than trying to uninstall/install every driver and see which of them is causing the problem.

I should sue them and ask a part of money back! I didn't give all that money to lost a few days to debug some problem on my brand new laptop !! There should be no problems on a brand new laptop !! I'm so mad right now....

 

I really doubt that it's an IRQ conflict.

Removing the older version altogether first is ideal. Overwriting a driver can sometimes create conflicts. Go with whichever drivers are more current from the site in lieu of the disc.

 

@Injection,
Did you found a solution to this problem?

I'm currently facing the same problem and it is killing me.

 

Nope, I fixed the keyboard problem by removing touchpad driver but this is just a temporary solution.

Thank you for replying.

That answer is actually quite valuable to me, because any kind of fix is better than no fix at all. In my case I use a mouse (I just don't like touchpads), so if uninstalling the touchpad woud fix my problem, I will gladly do that.

Of course it is unacceptable that something has to be sacrificed to make the keyboard work properly, but at least it is something.

 

You're welcome. Sorry for short reply, I was a little bit drunk and it was 4 AM here in my country

After I removed the touchpad driver, I didn't experience this keyboard problem not even once, which is great because this problem was really disturbing. And yes, I'm using mouse as well so it doesn't bother me too much. Also, the touchpad will continue to work without driver so you can use it. You will only lose some features like scrolling, swipe, gestures etc. But touchpad will continue to work.

I also have a problem with touchpad and I don't know should I bring it to the repair center again. The whole touchpad can be pressed and it pretends as left mouse click. The problem is when I want to press right button (right click); if I press too strong it will press right and left button at the same time.

I agree that this is unacceptable but I'm hoping that they will fix this, because it sounds like a software related problem.
