If your desktop or laptop computer spontaneously wakes up shortly after you place it into Sleep mode, it is usually caused by hardware peripherals or software network adapters sending automated "Wake-on-LAN" or USB interrupt signals. Common culprits include a sensitive optical mouse, a mechanical keyboard registering desk vibrations, or a network interface card configured to wake the PC upon receiving router traffic. To fix this, open the Windows Device Manager, locate your mouse, keyboard, and network adapter, right-click each device to open Properties, navigate to the Power Management tab, and uncheck the box that says "Allow this device to wake the computer." You can verify success by putting the PC to sleep and confirming it remains powered off peacefully.
