==== 1) Turn the mouse LEDs off while the laptop is on (quick toggle) ====

Many units have a built-in toggle:
* Press and hold the DPI button (the DPI switch near/behind the scroll wheel) for ~2–3 seconds → the lighting turns off.
* Press-and-hold again to turn it back on.

Note: multiple owners report it may not “remember” the off state after unplug/reboot. Amazon UK<ref>{{cite web|title=Amazon UK|url=https://www.amazon.co.uk/Acer-Adjustable-Including-Lighting-Optional/dp/B09XBJLX5F|publisher=Amazon UK|access-date=2025-12-20}}</ref>

Also, the official product info indicates the LED behavior is tied to DPI stages (color changes as DPI changes), which is why there often isn’t a separate “LED off” button shown in marketing.
