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!

That is the button behind the "emergency reset hole" in the bottom case panel. It's explained in the user manual.

    No idea what the button is and I found nothing about it in the Hardware Maintenance Manual
