XPS 13 keyboard lag in typing / not smooth / clicking the key doesn't always type

My first thought is that you may have accidentally invoked some of Windows Ease of Access settings. Try the steps in this reference:
7 Ways to Fix Keyboard Input Lag on Windows 10 (makeuseof.com)

 Unfortunately, not the case here, all of the ease of access settings are off.

Did you check the other settings mentioned in the link that I provided?

Unfortunately, none of the steps in the link have helped. It's real annoyance...

Any other ideas perhaps?

I've tried & external keyboard works absolutely fine. I.e., the issue is only for internal keyboard

Have you tried an external keyboard? Does the issue occur with an external keyboard?

delluserlith,

I see that our Dell Agent is waiting on you to respond back to continue troubleshooting.

Yes, however, no solution yet. I.e., Nothing has helped.

delluserlith,

Please continue working with our agents to resolve the keyboard issue.

I have solved my issue by disabling Filter keys. here

I'm also having this issue. Usually use a logitech external keyboard. Internal key board is useless. 

Hey everyone,

just wanted to post here that doing a BIOS update from the installed 1.5 to the much newer 1.21 fixed it for me and the tiping is now as expected.

@JakobD​ Do you have 1.21 link? I have the same problems for years and this laptop is always in the bag. I just update to 1.13 Oct 2020. Still fine now.

@jai_magical​ problems not solved. still intermittent. Also wifi is shown no adapter sometimes. Trackpad is not working sometimes.

Hi,

I have the same issue:

- external keyboards work perfectly

- laptop keyboard is intermittent: I have to press keys with a couple of seconds interval otherwise sometimes they don't work

I tried everything mentioned in this post, but nothing works

my laptop model is XPS 13 9340
