Frequently Asked Question
1. Immediate Physical & Hardware VerificationBefore diagnosing software, eliminate the most common physical points of failure.
- Reseat and Rotate Ports: Unplug the device and plug it back into a different USB port. For desktops, prioritize the rear USB ports directly on the motherboard rather than front-panel or hub ports.
- Check Power & Batteries:
- Wireless/Bluetooth: Ensure the power switch (bottom or back) is ON. Replace batteries with fresh ones; weak batteries often cause intermittent lag before total failure.
- Dongle Placement: Ensure the USB receiver is within 10 feet (3 meters) of the device and not blocked by metal objects or the PC case.
- Test on Another Device: Connect the keyboard/mouse to another laptop or PC. If it still doesn't work, the hardware is likely defective.
2. Standard Software Fixes (SOP)If the hardware works on another PC, the issue is within the local Windows environment.
- The "30-Second Hard Reset": Shut down the PC, unplug it from power, and hold the power button for 30 seconds to drain static electricity from the motherboard's USB controllers.
- Graphics/Driver Reset Shortcut: Press
Win + Ctrl + Shift + Bto force a driver refresh [Ref: Knowledge Base Standard]. - Disable Selective Suspend: Some power settings turn off USB ports to save power.
- Go to Control Panel > Power Options > Change plan settings > Change advanced power settings.
- Expand USB settings > USB selective suspend setting and set to Disabled.
3. Driver & Device ManagementIf you can use a touchscreen or have one working device (e.g., a working mouse but dead keyboard), follow these steps:
- Uninstall Drivers:
- Right-click the Start button and select Device Manager.
- Expand Keyboards or Mice and other pointing devices.
- Right-click the problematic device and select Uninstall device.
- Restart the PC. Windows will automatically reinstall a generic, working driver upon reboot.
- Check for Conflicts (Safe Mode): Boot into Safe Mode by holding Shift while selecting Restart. If the devices work in Safe Mode, a third-party software (like gaming macros or antivirus) is likely blocking them.
4. Advanced 2025 "WinRE" Loop IssueNote for late 2025: A known Windows security update (KB5066835) may cause USB devices to fail specifically within the Windows Recovery Environment (WinRE).
- The Fix: If you cannot use your mouse/keyboard in the recovery screen, use a bootable Windows 11 USB created on another PC to access repair tools, as this uses independent drivers.
