Mouse or keyboard stops working after computer wakes from sleep

Input devices failing after sleep is usually a USB power management issue, not a hardware fault, since the devices typically work fine again after a restart.

Symptoms

  • Mouse and/or keyboard unresponsive right after waking the computer
  • Devices work fine after a full restart
  • Issue happens consistently after sleep/hibernate, not otherwise
  • Wireless receiver light is off after waking

Likely causes

  • CommonUSB port power-saving setting turning off ports during sleepWindows can be set to cut power to USB ports to save energy, and sometimes fails to restore it properly on wake.
  • CommonWireless receiver failing to reinitialize after sleepSome receivers need to be unplugged and replugged to reconnect after a sleep cycle.
  • PossibleOutdated USB or chipset driversDriver bugs can specifically affect wake-from-sleep behavior.
  • PossibleFast Startup or sleep setting misconfiguration (Windows)Certain fast startup configurations can cause peripheral issues on wake.
  • Less commonBIOS/firmware power settingsSome system firmware settings affect how USB power is handled during sleep states.

What to do

  1. Unplug and replug the mouse/keyboard's USB receiver (or cable) after the computer wakes to see if that restores function.
  2. In Device Manager, under USB Root Hubs, uncheck 'Allow the computer to turn off this device to save power' in Power Management for each hub.
  3. Try pressing a key or clicking before fully expecting response, since sometimes there's a brief delay reinitializing devices.
  4. Update USB and chipset drivers from the computer manufacturer's website.
  5. Turn off Fast Startup in Windows Power Options and test if the issue improves.
  6. Try a different USB port for the receiver or cable, especially one directly on the motherboard for desktops.
  7. If only one device is affected, test it on another computer to rule out a device-specific fault.

When to call a pro

If devices consistently fail after sleep even after adjusting power settings and drivers, a technician can check for a deeper firmware or hardware power management issue.
