How to turn off LED lights on Acer Nitro Gaming Mouse II connected to Acer Nitro V 17 AI laptop?

Here are the practical ways people typically shut off (or stop) the LEDs on the Acer Nitro Gaming Mouse II / Nitro Mouse II (often listed as NMW120 / GP.MCE11.xxx).

1) Turn the mouse LEDs off while the laptop is on (quick toggle)[edit | edit source]

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[2]

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. Acer United States[3]

2) If Windows 11 is controlling it (Dynamic Lighting)[edit | edit source]

On some RGB peripherals, Windows 11 can manage lighting via Dynamic Lighting:

  1. Settings → Personalization → Dynamic Lighting
  2. Toggle “Use Dynamic Lighting on my devices” Off (or select the mouse and set brightness/effects).

If your mouse doesn’t appear there, Windows can’t control its LEDs this way. Microsoft Support[4]

3) If the LEDs stay on after shutdown/sleep[edit | edit source]

That usually means the USB port is still supplying power (“power-off USB charging”). On Acer systems, common fixes are:

  • In Acer Quick Access: turn off the USB charging / “charge on USB” / “power-off USB charging” option
  • In Windows power settings: disable Fast Startup
  • In BIOS/UEFI (if available): enable ErP (cuts standby power to ports)

These are the exact directions suggested in Acer’s community for “mouse lights stay on after shut down.” Acer Community[5]

4) If none of the above works[edit | edit source]

Acer’s own support page for the Nitro Mouse NMW120 shows no driver/download utility, so there may simply be no official software switch for LED control on some variants. Acer United States[6] As a non-destructive workaround, people commonly cover the LED window with opaque tape to block the light. Acer Community[7]

If you tell me whether you want the LEDs off only while using the laptop, or also when the laptop is shut down, I’ll point you to the best option for that specific situation.
