# Disable USB selective suspend: fixing a mouse or keyboard that lags after idling

**Short answer:** USB selective suspend lets Windows put a single USB port to sleep when the device on it is idle. Waking it takes a moment, which shows as a mouse, keyboard or headset that responds late after a pause. This tweak turns the setting off in the active power plan. It runs powercfg /SETACVALUEINDEX SCHEME_CURRENT SUB_USB 48e6b7a6-50f5-4782-a5d4-53bb8f07e226 0 and 2 more commands.

## In the app

- Switch: USB/HID Low-Latency Power Settings (Power, Pro, Advanced)
- Undo: Yes. Switching it off sets a standard Windows value, which may not be exactly how you had it.
- Game profiles that switch it on: Apex Legends, ARC Raiders, Battlefield 6 and 18 more

## What it does

USB selective suspend lets Windows put a single USB port to sleep when the device on it is idle. Waking it takes a moment, which shows as a mouse, keyboard or headset that responds late after a pause. This tweak turns the setting off in the active power plan.

In the app the switch is called "USB/HID Low-Latency Power Settings", described there as: Disables USB selective suspend to prevent mouse/keyboard sleep-induced lag.

## When it helps

- Input devices and USB audio that stutter or drop out for an instant after not being used.

## When it hurts

- USB devices draw a little more power at idle. On a desktop that is irrelevant; on a laptop it shortens battery life slightly.
