How Do I Find Out What Prevents My PC from Sleeping?
1. Open Command Prompt as administrator (right-click Start, select Windows Terminal (Admin)).
2. Type powercfg /requests and press Enter.
This command lists processes or devices currently preventing sleep. Address any listed under DISPLAY, SYSTEM, or AWAYMODE.
How Can I Analyze Power Usage and Battery Health?
Windows includes diagnostics for advanced users:

Review these reports to identify devices, drivers, or apps causing power issues.
How Do I Reset Power Plans to Default?
If you’ve made many changes and something goes wrong, reset all power settings:
1. Open Command Prompt as administrator.
2. Type powercfg -restoredefaultschemes and press Enter.
This restores all power plans to their original state.
Should I Update Device Drivers for Better Power Management?
Outdated drivers can interfere with power-saving features. Use Device Manager to check for updates, especially for graphics, chipset, and battery drivers. Glary Utilities also offers a driver update checker, allowing you to keep critical drivers up-to-date for optimal power performance.
Can Third-Party Tools Create Custom Power Plans?
Yes, tools like Glary Utilities allow you to manage startup items and optimize background services, which can complement Windows power plans. However, for creating detailed power plans, continue to use Windows’ built-in Power Options.
Real-World Example: Solving a Laptop That Won’t Sleep
A user notices their laptop stays awake even when the lid is closed. Using powercfg /requests, they find a USB mouse is listed under SYSTEM. By unplugging the mouse or disabling “Allow this device to wake the computer” in Device Manager (under the mouse’s Power Management tab), the issue is resolved.
