Point taken about it being a company laptop.
Try downloading the video driver for the Intel chipset directly from the Intel site, and not the one from Dell. You can always roll back the driver. AS far as I can remember it did alleviate the problem, but I did loose the right click Intel properties on the desktop.
At present I have an old XPS15z which is 8 years old, and needs replacing as some keys are playing up, a lot of trim is missing and it has been dropped on one corner so it is bent & broken! Still going though, and I think I can wait for the new version to be released, which should be soon.
Good luck with getting it sorted in the next couple of weeks, I bought mine in May 18, and it is still a problem. That was why I sent it back. If the problem is still with the new version, I will send it back straight away, and not wait weeks for Dell to "try" to sort it. Last time they were asking to re install the operating system, update all the drivers in a specific order, and then wanted to replace the keyboard. I had had enough with all that for a brand new £2500 machine!
@Swerving Thanks and good luck with the new one. I already tried the latest (legacy) Intel graphics drivers to no avail and Windows update downgraded it again when it next ran.
One other odd thing I've noticed is the backlights on my wired keyboard flash occasionally too as if the USB port is losing power, although other peripherals are fine.
It does feel like some sort of driver issue, it happens when the keyboard is plugged in directly to the USB port or via a dock.
I guess good questions are why doesn't everyone have this issue, does it only affect external keyboards, is there some common denominator?
I am having issues with skipping keys or keys not inputting (mainly q, w, e), as well as not being able to input a capital q, w, e using the shift key.
I have tried advice from this thread and also here: https://www.dell.com/community/XPS/Dell-XPS-15-9570-mouse-keyboard-lag-and-repeating-keys/m-p/728047...
Howeever, nothing seeems to work. Can anyone advise at this time?
