"1) Do you actually have superflous key strokes, along with that which is logged in dmesg?" Nope, totally asymptomatic.
"2) Could you please test the latest mainline kernel (now 5.9.1) and advise to the results?" Here ya go. I can attach entire dmesg if you want, but from 5.9.1 dmesg: [ 256.705741] atkbd serio0: Unknown key pressed (translated set 2, code 0x8d on isa0060/serio0). [ 256.705745] atkbd serio0: Use 'setkeycodes e00d <keycode>' to make it known. [ 265.118971] atkbd serio0: Unknown key pressed (translated set 2, code 0x8d on isa0060/serio0). [ 265.118975] atkbd serio0: Use 'setkeycodes e00d <keycode>' to make it known. "3) Did you personally test this with your Inspiron 1545 in a prior version of Ubuntu" No. I don't think it started logging this (at least often enough to notice) until my battery went from holding like a minute or two of battery life to holding 0, which only happened in the last 2-4 weeks. Honestly, I'd be totally fine if it was closed "wontfix" (I guess launchpad doesn't have that) or "invalid", the kernel's logging a non- standard keystroke sent by the Dell, which seems legitimate and harmless (it'd be a nuisance if it was every second but it's not close to that); in addition the Dell is effectively sending it in response to a hardware failure, so I could see "if you don't want this in your kernel log, replace your battery" being a legitimate response.
