Dell XPS 9550 F1, F2 and ~ not working (again!)
I have had my Dell XPS 9550 for four years now.
Two years ago my keyboard made some troubles, because three keys (namely F1, F2 and ~) became unreliable at first (i.e., they would only react sometimes on key press) and then stopped working completely (note: of course, I am talking about the keys at a whole, i.e., they would also not work in Fn mode to mute or decrease volume). All other keys (including F3-F12 and Esc) worked flawlessly I ordered a replacement keyboard and all keys worked again.
A week ago the issue started again, i.e., F1, F2 and ~ (and only those three keys) stopped working occasionally and now do not react at all.
It appears obvious that it is a hardware issue, because the key presses are not registered. However, I am a bit surprised that the exactly the same issue occurred again and that I did not find any other reports of this issue. This makes me ask if the issue is/was with the keyboard or with the connection to the motherboard or something else (something that I may have fixed accidentally when replacing the keyboard). I have no idea how to check that, but it is just so surprising that it is just exactly these three keys again that stopped working all of the sudden.
Did anybody experience the same issue? Do you have any suggestions for other checks / resolution attempts, apart from just ordering another replacement keyboard (which may fail again in two years).

Having the same problem: ~, F1, F2 will not work after wake or reboot. If you press the buttons insistently they eventually start working. Wiggling the charging cable indeed helped once.

Same problem. First it worked to genty disattach the key top and "viggle" the part below. Not even that doesn't help. My assumption is that these three keys share the same hardware connection and that might be faulty or has some microcorrosion?
Anyone found a solution already?

Having the same issue here. Has anyone come up with a solution?
Beside of the F1 - F2 issue, I'm having problems with the USB-C port as well, when I connect a USB-C disk to it, most of the times it cannot get recognized, but if I connect a usb hub, and connect a HDMI cable to the hub (thru the USB-C port), I get video, but if I connect a memory stick to that same port, nothing happens.
Anyone having similar problems?

Same F1 / F2 problem here and I have an XPS 7590 - very inconsistent behavior! Seems to randomly work sometimes and then it just stops!

Is your tilde/backtick key working? (~/`). I still have to use onscreen keyboard to tap these characters. Super annoying.

Also not working. It *seems* that if I hold one of them for a few seconds they decide to work again for a few minutes (yes I hold 1 of them and all 3 start working again - go figure).

yes, this is the same issue. My 'holding' pattern stopped working. They mostly not working now. They woke up one day all of a sudden (accidentally found they are working) but stopped working later the same day. Tried flashing BIOS back and forth to no avail. And F2 definitely not working at boot time to invoke the BIOS Setup. Has to use F11 workaround... Worse now, my %/5 key started to respond poorly. 4 and 6 are also lagging sometimes. I think I will open a case with Dell and ask them to fix it. Even if it will cost me, I don't care.

Have exactly the same issue, XPS 15 9570. Nothing helped (BIOS reinstall, "push patterns" etc...).
It's quite disappointing that Dell ignore such a frequent issue for 2+ years.
Looks like red flag for upgrade to new XPS

I have fixed the issue. It was a hardware issue. Keyboard replacement solved it. As warranty on my laptop is expired it was easier and cheaper to do replacement myself. It could be a hardware design flaw that creates exactly the same pattern of faulty keys.

Hey everyone, I did what's explained at 0:44 in the video below. It seems to have worked (at least for the time being). A driver issue is puzzling, but go figure.

Have the same problem with my 9570. It started to occur after using a laptop for about 2 years. ~ and F1, F2 work sometimes when incessantly clicking those buttons about 10-15 times.
Very disappointing.

Same problem here.
I think it started after i upgraded from Ubuntu 21.10 to 22.04 LTS.

I've a Dell laptop XPS 15 7590.
For my laptop i've solved this issue by selecting a different keyboard configuration (trial-and-error)
sudo dpkg-reconfigure keyboard-configuration
Select the "Dell Precision M65 laptop" model, US etc.
Finally solved!
