My keyboard stops working intermittently as I am using it. This started around a week ago without any particular reason or change that happened in my day-to-day usage of the device. The RGB still lights up and pressing the Mute Mic and Windows Lock keys still changes the color effect. Fn and F1 also seem to be working.

*Shoker* It just happened while I was writing this.

I’ve tried various key binds for keyboard locks I’ve seen using the on-screen keyboard to no avail.

I ran SupportAssist to update drivers with no result.

I have restarted/shut down, made sure the keyboard driver is up to date, made sure filter keys were not enabled, and disabled Windows power management for the keyboard. 

As suggested by previous posts, I checked the firmware update for my device and there were none. Then I downloaded the cherry firmware utility for the overall model and it seemed to run fine. I got a result "PASS", and status "2". However, after a Restart, the same issue appeared within minutes. I tried turning off power management for the keyboard, overall system power saving, HID firmware upgrade, and many other things. Nothing helps. It's a 2-year-old laptop.

After the keyboard stops working, I need to change some settings in Alienware CC to get it running again. Fn+F1 helps sometimes. Another way is to open the on-screen keyboard and press Scroll Lock. But it's annoying and extremely inconvenient to have to do this every 5 seconds.
