[Bug 1901083] [NEW] Inpsiron 1545 -- superflous key stroke logs (translated set 2, code 0x8d)

You have been subscribed to a public bug:

I posted some information on bug #549741 stating that I was getting similar logs to what people were seeing in there, and was advised to go ahead and file a bug. In dmesg, I get a pair like:
[ 529.926369] atkbd serio0: Unknown key pressed (translated set 2, code 0x8d on isa0060/serio0).
[ 529.926374] atkbd serio0: Use 'setkeycodes e00d <keycode>' to make it known.
[ 536.168508] atkbd serio0: Unknown key pressed (translated set 2, code 0x8d on isa0060/serio0).
[ 536.168512] atkbd serio0: Use 'setkeycodes e00d <keycode>' to make it known.

This pair will be like 2-10 seconds apart, then it could be 5 minutes or
more between pairs.

I've been running 5.7.19 kernel (installed via mainline), but did boot
5.4.0-52-generic to file this since it's a supported kerenl (I seriously
doubted it would make a difference since this has apparently been logged
since at least the 2.6.x kernel series, and it didn't.)

I consider this bug pretty minor to possibly invalid; these keystroke
messages spam up the kernel log a little but not too badly (since I'm
not getting them every second like the original poster in #549741, but
rather getting one, getting another a few seconds later, then it may be
5 minutes or more before I get another pair of them a few seconds
apart.).

My battery packed up quite a while ago and shows 0% charge.. it has
begun every so often "dropping off" and back on a few seconds later,
both in gkrellm, and whatever app shows the battery icon in top right
(near network manager, volume, etc.) I think it sends this 0x8d each
time the battery status changes.
