Edit: this guide doesn't seem to mention it https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t480-type-20l5-20l6/20l6/20l6s01q2y/document-userguide
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!
