How to Fix Switch Sleep Mode Issues: Console Won’t Wake Up

If your Switch won’t wake up from Sleep Mode, start with a hard reset—hold the power button for 15 seconds until the console turns off, then press it again to restart. This resolves most software glitches causing the issue. Check if the battery is drained: connect the official charger for 30 minutes, then try waking it. If using the dock, ensure the console is properly seated and the dock has power. Disable 'Auto-Sleep' temporarily in 'System Settings' > 'System' > 'Auto-Sleep' to see if it prevents future issues. If the problem persists, update your system firmware to the latest version, as outdated software often causes Sleep Mode bugs.
