Re: XPS 15 9570 Keyboard Skipping Keys

Strange you say this - I also thought my laptop got a bit faster after disabling panel self refresh, but I thought it must be me because that doesn't make sense.

Maybe it's some weird Intel GPU driver bug that causes keystrokes to be missed?

Re: XPS 15 9570 Keyboard Skipping Keys

i think because it was causing an input lag... at least thats my theory

Re: XPS 15 9570 Keyboard Skipping Keys

Hm, could be...

Whenever the panel self refresh was doing its thing (skipping a refresh frame), the keyboard would skip a key as well. And it would happen only if the key was pressed at the exact same moment when the display frame was skipped. Or something like that...

I suppose Dell engineers (and Intel's!) need to sort out those mixed up overlaps between the keyboard and the screen.

Is it me or newest BIOS update fixed that?

Re: XPS 15 9570 Keyboard Skipping Keys

I've seen the panel refresh re-enable itself.  I'm not sure under what circumstances, but it explains why my wife's laptop started missing keyclicks again.

Re: XPS 15 9570 Keyboard Skipping Keys

It must have been Windows updating the Intel graphics driver, and that made it re-enable the panel self refresh.

It would be good if Dell issues the BIOS fix soon, so we don't have to think about this...

Re: XPS 15 9570 Keyboard Skipping Keys

On my 9570, disable panel self refresh does not fix the problem. The self refresh is already disabled from day one due to screen will dim itself if switch to dark background and back to white page, very annoying for web development work.

After updating to bios 1.3.0 it is much better, but it still happens occasionally.

As a Web/SQL developer, i do a lot of typing, the skipping keys still happen but a lot less after the bios update.

Re: XPS 15 9570 Keyboard Skipping Keys

Hi,

Same issue here on my XPS 9570 4K.

I noticed that it is particularly obvious when you press the same key rapidly over and over again like that : AAAAAAAAAAAAAA there is only 14 "A", but I swear I press "A" 20 times... 😕

I'm running on the latest BIOS, latest Windows Version...

Please Dell, do something, this is incredibly annoying.
