Allow Keyboard and Mouse to Wake up PC

If your Windows PC is not waking up from sleep when you press a key on the keyboard or move the mouse, there are a few troubleshooting steps you can try.

First, check your power settings. Open the Control Panel and go to Power Options. Click on “Change plan settings” for your current power plan, then select “Change advanced power settings.” Look for the “USB settings” and “Power buttons and lid” options. Expand these categories and make sure the settings allow the keyboard and mouse to wake up the computer.

If that doesn’t work, you may need to update your device drivers. Visit the manufacturer’s website for your keyboard and mouse and download the latest drivers. Alternatively, you can use a reliable driver update tool like Driver Easy to automatically update your drivers.

Another possible solution is to check your BIOS settings. Restart your computer and enter the BIOS by pressing the appropriate key (usually Del, F2, or F10) during startup. Look for an option related to power management or wake-up events and make sure it is enabled.

If none of these fixes work, there may be a deeper issue with your system. You can try running the Power Troubleshooter in Windows 11 by going to Settings > System > Troubleshoot > Additional troubleshooters. Select “Power” and follow the on-screen instructions to fix any power-related issues.

Sleep is good, but waking up is even better. Don’t let your PC slumber away, wake it up and get things done.
