Did you know you could control brightness of the red dot on the i of the "ThinkPad" on the top-side of your thinkpad? I sure didn't:

this turns it off:

echo 0 | sudo tee /sys/class/leds/tpacpi::lid_logo_dot/brightness

and this turns it on:

echo 255 | sudo tee /sys/class/leds/tpacpi::lid_logo_dot/brightness

I don't really know what this information is good for, but hey, isn't it awesome to have a 1px display on the outside of your laptop?
