Bug Report: A03 bios for Dell XPS 13 (2015) causing keyboard repeating keypresses

I'm still having the same issues with A04. Not much change if any at all.

I don't understand how Dell could issue a fix that has no (or almost no) effect. Very disapointing.

For those looking for a patch solution, look for the autohotkey script posted earlier in this thread. Works good for me, I changed the debouncing timing to 100 ms.

I'm getting good results. I typed for about 20 minutes straight and saw repeat keys maybe twice so it's much better. I also had a bug where the enhanced pointer precision box in mouse properties would uncheck itself when I cold booted this laptop. I've powered the laptop off then back on about 5 times and so far the box stays checked.

I updated to A04 this morning and so far I have not see the stuck key behavior. However, the fact that Dell let this get to customers the first time does not fill me with confidence. I will post again if I see it.

A04 fixed it for me.

My experience: Very significant stuck key issue which was significantly reduced moving from A03 to A04 - so software issue right? Well no, because my replacement laptop arrived (with A03) and this issue is not there at all - not one single double key so far. So it looks like a combination of both hardware and software.

May or may not be relevant: Touchpad and lower part of keyboard were slightly rattly / springy on my first unit - the replacement is much more solid. May be a factor as for me space bar was the worst.

HTH

I just bought the XPS 13 9343 with Ubuntu pre-installed and I have similar problems. The BIOS is A03. It seems that sometimes it misses a key event. If it misses a key-down you have a missing character, if it misses a key-up event you have repeated characters until another key is pressed. The same happens with the track pad. Occasionally misses a series of motion events and freezes for a sec or two and then the pointer jumps to where it should have been if it did not miss the motion events.

I take back my last post. I'm still getting double keypresses like crazy on A04, especially C and space. Six corrections in this post alone. 

Be aware that the problem can return. I sent mine back for a replacement and it was good for a month or so but this week the new laptop started making repeated keys too! I've just updated to A04 so hopefully that will improve it. However it makes me worry that the issue may start up again after 6 months or a year or two when the guarantee has expired.

Also FYI official recognition of the problem from Dell www.dell.com/.../EN

Here's a fix by Dell (fixing keyboard characters occasionally getting stuck):

It seems to have fixed it for me!

Same problem mostly with n and space bar but always tried telling myself it must just be me until findinng this!

Problem (finally) fixed for me after upgrading to bios A05!  

A02 and A04 were supposed to fix it but didn't work on my computer, but looks like A05 nailed it!

good luck.

See the message below please. It has the fix which -regardless of the BIOS- fixes the problem for me.

It's Windows only (no Linux) but if you are a Linuxy guy, you can take the idea and code it for nx also!

Good luck guys!

Hey! I had the same problem in the past with my Sony Vaio Z Series and developed a fix for it, here you can get it: https://goo.gl/C3jdfs

If you have any questions let me know. I've updated the fix today so it filters a bit better than with my old Vaio. In this new Dell I realized the bounce is so big that it sometimes the a key may be repeated even after I press a new one. In other words, I want to write "hello", this might happen:

hehllo <-- The "h" was repeated *even* after my keydown on the e.

So, the fix (see the asm source in the zip file) contemplates also that. I'm using it and it's working well. Let me know if you have questions.

Thanks,

Magic.

I experience exactly the same character repeat issue on a Dell XPS 15. For XPS 13 a Bios update seems to solve the problem, but what about XPS 15?
