Additional Tips

• Prevent Sleep Mode Temporarily: You can set your device to never sleep by selecting “Never” in the sleep settings. However, for long-term use, it’s best to have sleep mode enabled for energy efficiency.
• Using Command Prompt or PowerShell: Advanced users can modify sleep settings using commands like powercfg. For example, powercfg /change standby-timeout-ac <minutes> can be used to set sleep timeout for AC power mode.

Troubleshooting

• Sleep Option Not Available: If the sleep option is missing, you may need to update your graphics drivers or check if there are any settings in BIOS/UEFI affecting sleep modes.
• Device Doesn’t Go to Sleep: Background processes or apps might prevent the computer from sleeping. Check Task Manager for high-resource apps and close them if necessary.
