Comment 98 for bug 549741

I have an Inspiron 1545 that's doing this (Ubuntu 18.04.5); mine is nowhere near every second though. My battery is toast, a while ago it began (occasionally) having the "0% battery" occasionally drop off then reappear a few seconds later (both in gkrellm and the battery status on the top right near network-manager etc.). Based on the timing in the logs (0x8d then another a few seconds later), I think it sends a 0x8d keystroke both on battery disappearing and once on reappearing.

I'd hesitate to consider it a bug; it's minorly spamming up the logs with a superfluous keystroke the Dell's sending, while causing no harm (if the point of the keystroke is to indicate change in battery status, Linux is already well aware of this via ACPI anyway.)
