没有工作键的键盘似乎对生产力造成了打击，但可以修复。如果您一直在使用 PC 并突然在计算机屏幕上出现一些字符或没有字符，我们将向您展示如何修复它。

如果您有台式 PC，只需更换键盘并使用不同的键盘即可。但是对于笔记本电脑来说，这是不可能的，这使它成为一个大问题。

可能是您的计算机可能需要进行一些简单的硬件或软件维护，或者您的键盘设置设置为使用错误的语言或地区。

在您访问维修店、购买新键盘或完全丢弃笔记本电脑之前，请尝试以下一些快速修复方法。此外，请务必查看我们的 YouTube 频道，我们在其中发布了一段简短的视频^{(short video)}，介绍了本文中的一些修复。

注意：^{(Note: )}以下说明适用于Windows PC。

修复停止工作的键盘键^{(Fix Keyboard Keys Which Stop Working)}

• 快速检查
• 清理键盘
• 重启你的电脑
• 使用不同的键盘
• 检查区域或语言设置
• 调整键盘输入设置
• 运行恶意软件扫描
• 重新安装键盘驱动
• 访问服务技术/更换键盘

快速检查^{(Quick Checks)}

• 如果您使用的是蓝牙^(Bluetooth)键盘，请检查它是否已开机且已连接。
• 将键盘与计算机重新配对^(Re-pair)（对于无线键盘）。
• 尝试不同的USB端口（有线键盘）。
• 检查键盘的电池电量，因为它可能会导致性能问题。

如果在执行这些基本检查后键盘按键仍然不起作用，请尝试以下解决方案。

清理键盘^{(Clean Up The Keyboard)}

清洁标准键盘并不容易，但与笔记本电脑键盘相比，如果您有无线或USB键盘，则更容易清洁。^(USB)这可能不一定能解决键盘按键的任何深层次问题，但如果碎屑和污垢阻止键盘按键工作，它会有所帮助。

清理笔记本电脑^{(clean up the laptop)}键盘：

• 关闭^(Shut)设备，将其倒置，然后轻轻敲击底座，以免损坏整个设备。  
•  用手指划过按键，清除残留的任何碎屑或污垢，完成后清洁桌面。
• 拿起^(Pick)一个压缩空气罐并给它一个很好的爆炸，或键盘清洁腻子以去除任何卡住的污垢。
• 如果按键因为液体溢出^{(liquid spills)}而卡住，请从键盘上弹出按键，并尝试尽可能多地清除按键开关上的干燥液体。要在不折断的情况下取下钥匙，请将指尖或一字螺丝刀放在钥匙的一角下方，然后轻轻撬起，直到它弹出。您可以在抹布或棉签上涂抹一些肥皂水或酒精，以清除任何残留物。

重启你的电脑^{(Restart Your PC)}

重新启动有助于刷新系统并纠正可能导致键盘按键不起作用的任何软件故障。

使用不同的键盘^{(Use a Different Keyboard)}

尝试连接不同的USB或无线键盘，或使用Windows屏幕键盘，看看是否有帮助。如果是这样，那么您当前的键盘可能有缺陷。

检查区域或语言设置^{(Check The Region Or Language Settings)}

当您的键盘语言或布局设置错误时，您可能会在屏幕上看到与键盘上显示的字母不同的字母。这是基于不同地区使用的不同字符而发生的，因此键盘布局在所有地方都不相同。

要更正此问题，请使用以下步骤更改区域或语言设置：

• 单击Start>Settings>Time & Language。

• 单击区域^(Region)以选择您当前的区域。

• 单击语言^(Language)，然后单击添加首选语言^{(Add a preferred language )}为您的键盘选择正确的选项。

• 单击下一步^(Next)，然后单击安装^(Install)。

• 转到“语言^(Languages)”部分并为您的键盘选择新语言，然后再次尝试输入几个字符以查看它是否有效。
• 您还可以通过返回语言^(Language)更改键盘选项，单击当前键盘语言，然后单击选项^(Options)以选择键盘类型。例如，美国用户将使用英语（美国^(States)）^(English)作为他们^(United) 的键盘语言，并使用美国 QWERTY^{(US QWERTY)}键盘布局选项。

调整键盘输入设置^{(Adjust Keyboard Input Settings)}

您的键盘按键具有某些可能导致行为不稳定^{(erratic behavior)}的软件设置，即使它们本来是有用的。您可以调整此类输入设置，例如过滤键^{(Filter Keys)}、粘滞键^{(Sticky Keys)}或重复延迟^{(Repeat Delay)}设置。

如果按特定键键入多个字符：

• 单击Start>Control Panel 并在控制面板搜索栏中搜索键盘^(Keyboard)。

• 在速度^(speed)选项卡下，调整重复延迟^{(Repeat Delay)}设置并尝试再次输入字符。

• 如果按键与屏幕上显示的字符之间存在延迟，则需要调整Filter Keys。在搜索栏中输入轻松访问^{(Ease of Access)}，然后单击它。

• 单击使键盘更易于使用。^{( Make the keyboard easier to use.)}

• 如果已打开，请取消选中Filter Keys框，然后单击^{(Filter Keys)}OK。如果您的键盘正在运行，请在同一菜单中关闭粘滞键。^{(Sticky Keys)}

运行恶意软件扫描^{(Run a Malware Scan)}

听起来很疯狂，您的键盘可能感染了病毒^{(infected with a virus)}。使用您当前安装的防病毒软件运行恶意软件扫描，或尝试免费的在线恶意软件扫描程序以排除任何潜在威胁。

重新安装键盘驱动程序^{(Reinstall The Keyboard Driver)}

过时的驱动程序可能会导致您的键盘按键不起作用。但是，有时键盘驱动程序可能会出现故障，特别是如果您经常安装第三方软件，或者在不使用关机^{(Shut Down)}命令的情况下关闭计算机。

要重新安装键盘驱动程序，请执行以下步骤：

• 右键单击开始^(Start)并选择设备管理器。^{(Device Manager.)}

• 单击键盘^(Keyboards)以展开列表。在这里，您可以检查任何旁边可能带有黄色感叹号的条目，表明有问题。

• 右键单击键盘^(keyboard)并选择卸载驱动程序。^{(Uninstall Driver.)}
• 重新启动计算机，它会自动安装通用键盘驱动程序，之后您可以检查按键是否再次工作。

注意：^(Note:)您也可以访问计算机制造商的网站并为您的型号的特定键盘安装最新的驱动程序。如果它不可用，您可以重新安装USB驱动程序或芯片组。

更换键盘^{(Replace The Keyboard)}

如果这些解决方案都没有帮助，并且您的计算机仍在保修期内，您可以与制造商联系以获得进一步的支持和维修，或者完全更换它。

如果是笔记本电脑，请备份您的硬盘驱动器或在将其发送给服务技术人员之前将其移除，以免丢失您的宝贵数据。

How To Fix Windows Keyboard Keys Which Stop Working

A keyboard without working keys may seem lіke a blow tо productiνity, but it’s possible to reраir. If yoυ’ve beеn working on your PC and suddenly some or no characters appear on your computer scrеen, wе’re going to show you how to fix it.

If you have a desktop PC, it’s easy to just swap the keyboard and use a different one. For laptops though, this isn’t possible, which makes it a big problem.

It could be that your computer could use some simple hardware or software maintenance, or your keyboard settings are set to use the wrong language or region.

Before you visit the repair shop, buy a new keyboard, or chuck your laptop altogether, try some of the quick fixes below. Also, be sure to check out our YouTube channel where we posted a short video going over some of the fixes in this article.

Note: The instructions below apply to a Windows PC.

Fix Keyboard Keys Which Stop Working

• Quick checks
• Clean up the keyboard
• Restart your PC
• Use a different keyboard
• Check the region or language settings
• Adjust keyboard input settings
• Run a malware scan
• Reinstall keyboard driver
• Visit a service tech/Replace the keyboard

Quick Checks

• If you’re using a Bluetooth keyboard, check that it’s powered on and that it’s connected.
• Re-pair the keyboard with your computer (for wireless keyboards).
• Try a different USB port (wired keyboard).
• Check the keyboard’s battery level as it may cause performance problems.

If the keyboard keys still won’t work after carrying out these basic checks, try the solutions below.

Clean Up The Keyboard

It’s not easy to clean a standard keyboard, but it’s easier to do if you have a wireless or USB keyboard compared to a laptop keyboard. This may not necessarily fix any deep-seated issues with your keyboard keys, but it’ll help if debris and dirt are preventing the keyboard keys from working.

To clean up the laptop keyboard:

• Shut down the device, turn it upside down and then tap gently on the base to avoid risking damage to the entire unit.  
•  Run your fingers across the keys to dislodge any debris or dirt that’s left and clean the table when you’re done.
• Pick up a compressed air can and give it a good blast, or keyboard cleaning putty to remove any dirt that’s stuck.
• If the keys are stuck because of liquid spills, pop off the key from the keyboard and try to clean the dried liquid off the key switch as much as you can. To remove a key without breaking it, place the tip of your finger or a flathead screwdriver under a corner of the key and pry it up gently until it pops off. You can dab some soapy water or rubbing alcohol on a rag or cotton swab to clean away any residue.

Restart Your PC

A reboot helps refresh the system and correct any software glitches that could cause your keyboard keys not to work.

Use a Different Keyboard

Try connecting a different USB or wireless keyboard, or use the Windows on-screen keyboard and see if it helps. If it does, then your current keyboard could be defective.

Check The Region Or Language Settings

When your keyboard’s language or layout settings are wrong, you may see different letters on your screen than what’s indicated on the keyboard. This happens based on the different characters used in different regions, so the keyboard layouts aren’t the same everywhere.

To correct this, change the region or language settings using these steps:

• Click Start>Settings>Time & Language.

• Click Region to select your current region.

• Click Language and then click Add a preferred language to choose the right option for your keyboard.

• Click Next and then click Install.

• Go to the Languages section and select the new language for your keyboard, and then try typing a few characters again to see if it works.
• You can also change your keyboard options by going back to Language, click on the current keyboard language, and then click Options to select the keyboard type. For instance, US users will have English (United States) as their keyboard language, and the US QWERTY keyboard layout option.

Adjust Keyboard Input Settings

Your keyboard keys have certain software settings that may cause erratic behavior, even if they’re meant to be helpful. You can adjust such input settings like Filter Keys, Sticky Keys, or Repeat Delay settings.

If pressing a particular key types more than one character:

• Click Start>Control Panel and search for Keyboard in the Control Panel search bar.

• Under the speed tab, adjust the Repeat Delay settings and try typing the characters again.

• If there’s a delay between pressing a key and the character showing up on your screen, you need to adjust Filter Keys. Type Ease of Access in the search bar, and click on it.

• Click Make the keyboard easier to use.

• Uncheck the Filter Keys box if it’s on, and click OK. Turn off Sticky Keys in the same menu if your keyboard is acting up.

Run a Malware Scan

As crazy as it sounds, it’s possible that your keyboard could be infected with a virus. Run a malware scan using your currently installed antivirus software, or try a free online malware scanner just to rule out any potential threats.

Reinstall The Keyboard Driver

An outdated driver could cause your keyboard keys not to work. However, sometimes the keyboard driver can malfunction especially if you regularly install third-party software, or turn off your computer without using the Shut Down command.

To reinstall your keyboard driver, take these steps:

• Right-click Start and select Device Manager.

• Click on Keyboards to expand the list. Here you can check for any entry that could be having a yellow exclamation mark next to it, indicating a problem.

• Right-click your keyboard and select Uninstall Driver.
• Restart your computer, and it’ll automatically install the generic keyboard drivers, after which you can check if the keys work again.

Note: You can also go to your computer manufacturer’s website and install the latest drivers for the specific keyboard for your model. If it’s not available, you can reinstall the USB drivers or chipset.

Replace The Keyboard

If none of these solutions helped, and your computer is still in its warranty period, you can check with the manufacturer for further support and repair, or get it replaced altogether.

If it’s a laptop, back up your hard drive or remove it before sending it to a service technician, just so you don’t lose your precious data.
