首先檢查設(shè)備是否被手動禁用，2. 然後查看電源管理設(shè)置，3. 使用硬件疑難解答或重新安裝驅(qū)動程序，4. 最後考慮註冊表編輯（高級用戶）。遇到“This device is disabled (Code 22)”錯誤時，通常表示該硬件組件未激活，可能是人為關(guān)閉或系統(tǒng)故障所致；首先可在設(shè)備管理器中找到對應(yīng)設(shè)備並啟用它；若無效，則進(jìn)入電源管理選項(xiàng)卡取消“允許計算機(jī)關(guān)閉此設(shè)備以節(jié)省電源”的勾選；接著嘗試運(yùn)行Windows內(nèi)置的硬件疑難解答工具，或卸載設(shè)備後重啟電腦讓系統(tǒng)自動重裝驅(qū)動；如仍無法解決且具備相關(guān)技能，可備份註冊表後檢查對應(yīng)鍵值是否有禁用項(xiàng)並修改；大多數(shù)情況下無需觸及註冊表，建議僅在其他方法無效時才進(jìn)行此類操作。

If you're seeing the error "This device is disabled (Code 22)" in Windows Device Manager, it usually means the hardware component isn't active. This can happen for a variety of reasons — maybe someone manually turned it off, or there was a system glitch during an update. The good news? It's often fixable without needing to replace hardware.

Check if the Device Is Manually Disabled

Sometimes, the simplest explanation is the right one: the device might have been accidentally turned off.

• In Device Manager , expand the category that corresponds to your device (like Network Adapters or Display Adapters).
• Right-click the device and look at the context menu.
  • If you see "Enable device" , that means it's currently disabled.
  • Click it to turn the device back on.

If this doesn't work or the option isn't available, move on to checking hardware status or power settings.

Look Into Power Management Settings

Windows sometimes disables devices to save power, especially on laptops.

• Go to Device Manager , right-click the affected device, and select Properties .
• Go to the Power Management tab.
• Make sure the box labeled "Allow the computer to turn off this device to save power" is unchecked .

This won't always solve the problem, but it's worth trying, especially if the issue happens after waking your PC from sleep mode.

Use Hardware Troubleshooters or Reinstall the Driver

Windows has built-in tools that can detect and repair some device issues automatically.

• Open Settings > System > Troubleshoot > Other troubleshooters .
• Scroll down and run the Hardware and Devices troubleshooter.

If that doesn't help, try reinstalling the driver:

1. In Device Manager , right-click the device and choose Uninstall device .
2. Confirm the uninstall and then restart your computer.
3. Windows should reinstall the driver automatically on startup.

If you know where the latest driver is (from the manufacturer's website), you can also choose to Update driver manually after uninstalling.

Investigate Registry Edits (Advanced)

In rare cases, a registry setting might be preventing the device from starting.

• Press Win R , type regedit , and open the Registry Editor .
• Navigate to:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{device-class-guid}
• Look for a key named "Disabled" or similar entries under each subkey.
• If found, double-check before changing anything — incorrect edits can cause system instability.

Only go this route if other methods fail, and make sure to back up the registry first.

Fixing the "This device is disabled (Code 22)" error usually comes down to re-enabling the device, managing power settings, or refreshing drivers. Most users won't need to touch the registry, and it's best left alone unless you're confident in what you're doing.基本上就這些。
