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

    Ooh, this looks interesting.

    You've verified it's a button?

    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.
