如何修复'当前没有可用的电源选项”

首先运行电源疑难解答，然后使用管理员命令提示符执行powercfg -restoredefaultschemes命令重置电源方案，接着更新或重新安装ACPI驱动程序，检查组策略设置（仅限专业版/企业版），运行sfc /scannow修复系统文件，并通过创建新用户账户判断是否为用户配置文件问题，多数情况下电源选项会恢复正常。

If you're seeing the message "There are currently no power options available" in Windows (usually in Settings > System > Power & Sleep), it means the power plan settings aren't loading properly. This can prevent you from adjusting sleep, screen timeout, or performance settings. Here’s how to fix it step by step.

1. Run the Power Troubleshooter

Windows includes a built-in troubleshooter that can automatically detect and fix common power-related issues.

• Press Windows I to open Settings.
• Go to System > Troubleshoot > Other troubleshooters.
• Find Power, click Run.
• Follow the on-screen instructions and apply any recommended fixes.

This often resolves the issue immediately, especially if it's caused by a temporary glitch.

2. Rebuild the Power Plan Using Command Prompt

Corrupted power plan settings are a common cause. Rebuilding them using powercfg can help.

• Right-click the Start button and select Command Prompt (Admin) or Windows Terminal (Admin).

  

• Type the following command and press Enter:

  powercfg -restoredefaultschemes

• If successful, you’ll see: "Successfully restored all power schemes to default."

• Restart your computer and check if power options now appear in Settings.

? This command resets all power plans (Balanced, Power Saver, High Performance) to their factory defaults and re-registers them with the system.

3. Check for Hidden or Corrupted Power Plans

Sometimes power plans exist but aren’t showing up.

• Open Command Prompt as Admin again.

• Run:

  powercfg -list

• This will show all available power plans. If they’re listed but grayed out or marked as "GUID", they may be corrupted.

• Use the restore command from Step 2 to fix them.

4. Update or Reinstall Power Management Drivers

Outdated or faulty ACPI (Advanced Configuration and Power Interface) drivers can disable power options.

• Press Windows X and select Device Manager.

• Expand System devices.

• Look for entries like:

  • Microsoft ACPI-Compliant System
  • Intel(R) Management Engine Interface
  • ACPI Battery, AC Adapter

• Right-click each and choose Update driver > Search automatically.

• If that doesn’t help, right-click and select Uninstall device, then restart your PC. Windows will reinstall the drivers automatically.

⚠️ Don’t worry—these drivers are essential, but Windows will restore them on reboot.

5. Check Group Policy (For Pro/Enterprise Editions)

If you're on Windows Pro or Enterprise, group policies might be disabling power options.

• Press Windows R, type gpedit.msc, and press Enter.
• Navigate to:

  Computer Configuration > Administrative Templates > System > Power Management

• Check if any policies are set to Enabled that restrict power settings.
• Set them to Not Configured or Disabled.
• Restart your computer.

? This doesn’t apply to Windows Home unless you’ve manually enabled group policy.

6. Perform a System File Check (SFC)

Corrupted system files can cause missing UI elements like power options.

• Open Command Prompt (Admin).

• Run:

  sfc /scannow

• Wait for the scan to complete. If issues are found, it will attempt to repair them.

• Restart your PC after completion.

7. Create a New User Profile (If Issue Is User-Specific)

Sometimes the problem only affects one user profile.

• Create a new local user account (Settings > Accounts > Family & other users).
• Log in to the new account.
• Check if power options are visible.

If they are, the issue is tied to your original profile—consider migrating data or resetting settings.

Summary of Key Fixes

• ✅ Run the Power Troubleshooter
• ✅ Use powercfg -restoredefaultschemes in Admin Command Prompt
• ✅ Update or reinstall ACPI/System drivers in Device Manager
• ✅ Check Group Policy (if applicable)
• ✅ Run sfc /scannow to repair system files
• ✅ Test with a new user account

Most cases are resolved with the powercfg command or driver updates. If none work, a Windows repair install (keeping files/apps) can be a last resort. But in most cases, it's a quick fix.
