okay bestie, this is the kernel API page for the attention LED. no cap, she's short but iconic. 🫶

✨ SYNOPSIS ✨

       );

🎀 ARGUMENTS 🎀

• hotplug_slot — target hotplug_slot, aka the hotplug slot you're aiming at 🎯
• value — LED control value, the number that tells the LED what mood to be in 🌈

🦋 DESCRIPTION 🦋

okay so here's the whole vibe: the control values go like this, literally:

echo 0 > attention -- set LED OFF
echo 1 > attention -- set LED ON
echo 2 > attention -- set LED ID(identify, light is blinking)

So <pink>0</pink> is OFF, <mint>1</mint> is ON, and <purple>2</purple> is ID — identify mode, where the light is blinking. Slay. 💅
