如果Lenovo鍵盤無法使用，首先檢查物理問題或是否被意外禁用，嘗試重啟、更新驅(qū)動、運行硬件故障排查工具，最后測試外接鍵盤或檢查BIOS設(shè)置。具體步驟為：1.檢查鍵盤是否有雜物或損壞，嘗試插入其他設(shè)備；2.重啟電腦并更新或重裝鍵盤驅(qū)動；3.運行Windows內(nèi)置的鍵盤故障排查工具；4.連接外接鍵盤測試，同時進入BIOS確認(rèn)鍵盤未被禁用。若仍無改善，可能需聯(lián)系官方支持進一步處理。

If your Lenovo keyboard isn't working, it can be frustrating, especially if you're in the middle of something important. The issue could be software-related, a driver problem, or even a hardware fault. Here's how to systematically troubleshoot and potentially fix the problem.

Check for Physical Issues or Accidental Disabling

Before diving into technical fixes, make sure the basics are covered. If you're using an external keyboard, try plugging it into another port or even another device to rule out hardware failure.

For built-in keyboards:

• Make sure there’s no debris stuck under the keys.
• Avoid eating or drinking near the laptop to prevent future issues.
• Check if the keyboard was accidentally disabled. On some Lenovo models, pressing Fn Esc toggles the keyboard on and off — this varies by model and driver setup.

Also, look at system settings or third-party apps that might have disabled input devices without your knowledge.

Restart Your Laptop and Update Drivers

Sometimes a simple restart can resolve minor glitches affecting your keyboard.

After restarting:

• Open Device Manager (right-click Start menu > Device Manager).
• Expand Keyboards, right-click your keyboard device, and select Update driver.
• Choose Search automatically for updated driver software.

If that doesn’t help:

• Try uninstalling the keyboard driver completely.
• After uninstalling, restart your laptop — Windows will usually reinstall the driver automatically.

Make sure your Windows is up to date as well, since system updates often include fixes for peripheral issues.

Run the Built-in Hardware Troubleshooter

Windows has a built-in troubleshooter that can detect and sometimes fix hardware problems.

To run it:

1. Go to Settings > System > Troubleshoot.
2. Click on Other troubleshooters.
3. Find Keyboard in the list and click Run.

This won’t always find the exact issue, but it's worth trying before moving to more involved steps.

Test with an External Keyboard and Consider BIOS/UEFI Settings

If your built-in keyboard still isn’t responding:

• Plug in a USB or Bluetooth keyboard to see if it works.
• If it does, the issue is likely with the internal keyboard or its connection.

You can also check the BIOS/UEFI settings:

• Restart your Lenovo and press F2, Del, or Enter (depending on your model) when the logo appears to enter BIOS.
• Look for any option related to onboard devices or keyboard/mouse control.
• Ensure the keyboard is enabled here.

Keep in mind that changing BIOS settings should be done carefully.

If none of these steps work, the keyboard may be physically damaged or there could be deeper software corruption. At that point, contacting Lenovo support or visiting a repair shop makes sense. But for most common issues, one of these steps should get your keyboard working again — basically, start simple and move to deeper checks only if needed.
