…And, one should be able to turn of every led even when powered on… At Ikea I almost bought a nice brushed steel extractor hood, except it had this obnoxiously bright blue led on the front. Why? I know when that thing is on without it drawing my attention constantly.
Same with my Lenovo X13 gen 2, there is a bright white led next to the power button… just why…???
I don't know about the X13, but a lot of ThinkPads you can control the LEDs with some settings; /sys/class/leds/tpacpi::power/brightness on Linux (also some other knobs/LEDs in there).
Thus far this has worked on every ThinkPad I've had; but again, I don't know if it will work on your X13 (or how to do it from Windows or other systems), but something to look at if you haven't already.
Looking at the Linux source "tpacpi::power" is in the "TPACPI_SAFE_LEDS" list; the setting mentioned in that thread only protects things like "tpacpi::dock_active", "tpacpi::dock_status1", etc.
I checked, and my kernel doesn't have that option, and I can change it just fine ("echo 0 >/sys/class/leds/tpacpi::power/brightness", as root of course).
I like how modern routers have a button on the front to just turn off any LEDs, that's a great improvement I think.
Anyway I've got a speaker in my bedroom with an LED that won't turn off, and a USB-C hub that has a tiny blue LED that requires me to disconnect the whole thing first. Really annoying.
I have a TV with a flood light on the bottom when it's off and the IR receiver is also behind the translucent plastic for the light. It's in my bedroom and is bright enough to keep me up, so I have electrical tape over it which I then have to remove to use the TV because it doesn't have buttons.
