I was flashing Libreboot on to my ThinkPad T480, when I noticed this little button. Sorry for the poor images!

I haven't yet dares trying to press it, but looking at it with the naked eye, it does look like - for instance - the bootloader button on a Raspberry Pi Pico. Couldn't come up with another example. Lol.

Well, if the power is off/battery out you could safely push it to feel it.

Looks like a button to me, wonder of it's just a reset button.

Curious to hear from an expert though!
