Certain keys not registering occasionally (FW 16, RGB keyboard)

Occasionally some keys wouldn’t register (so far I’ve noticed it’s T, Y, and O keys that stops working) unless I press down on T key hard enough to get it registering again and that fixes other keys too, if I press down hard on other affected keys, that doesn’t solve it, it seems to be T key only that gets it sorted out.

This is on a Framework Laptop 16, with RGB keyboard, I’ve took off the input/keyboard cover and reseated the cable but that doesn’t solve it, only pressing down hard enough on T key gets it working again for a while, I’ve noticed that when it happens, it’s usually on system boot up and wake up, and when I fix it, often remains that way until I shut it down/put it in sleep and pick it up the next day, and it happens all over again.

I’m running Fedora 42 Workstation Edition on it, but I suspect it’s a hardware issue more than a software issue.

This probably isn’t the case, but just in case, I’ve noticed the keyboard stops registering keys if power control is enabled for the keyboard.

If you’ve got powertop installed, then Autosuspend for USB device Laptop 16 Keyboard Module - ANSI should be set to bad (ie, no auto-suspend) on the Tunables page.

Otherwise, I’m out of ideas. ;(

I can rule out power control related issues (it’s already set to ‘bad’ when I checked), I’ve kind of fixed these keys not registering by reseating the cable on the keyboard side instead of just on laptop side the previous times, but in doing so, there’s a new issue, it’s now windows/meta/super key, G, and H keys not registering sometimes, but only when it’s under heavy load and the keyboard gets a bit warm, pressing down hard enough gets them registering again though.
