如果您曾经有过重复键，您就会知道它有多烦人。每次你必须加倍删除重复的“i”或“s”时，你就会失去一点时间。它甚至可能会干扰您的思维流程，从而降低您一整天的工作效率。
好消息是重复键通常很容易修复，特别是如果它最终成为硬件问题。以下是修复那些讨厌的重复字母的一些故障排除步骤。
开始简单(Start
Simple)
与任何计算机问题一样，首先解决最简单的故障排除步骤很重要。如果您有另一个键盘，请将其插入并开始输入。
这将帮助您缩小现有键盘是否存在问题的范围。
清洁和维修钥匙(Clean & Repair Keys)
下一个相当简单的步骤是清洁键盘。您应该已经定期对计算机进行彻底清洁(a thorough cleaning)，但是您的键盘特别容易脏。
关闭(Shut)计算机并将键盘倒置以抖出任何松散的碎屑。擦拭按键并使用罐装空气清除可能被困住的任何污垢。然后，您可以再次将键盘倒置以消除罐装空气排出的东西。
如果这不起作用，您可能需要移除重复的键并用棉签清洁它们下方。
运行操作系统更新(Run
Operating System Updates)
如果您最近没有更新您的系统，那么快速的操作系统更新永远不会受到伤害。在Windows 10计算机上，转到Start > Settings > Update and Security > Windows Update。
对于MacOS，单击左上角的Apple图标并选择(Apple)App Store>Updates。您还可以(You can also)使用Windows Driver Booster之类的程序来检查是否有任何过时的键盘驱动程序并将其更新。
检查系统配置(Check
System Configuration)
一旦您对键盘进行了物理检查并排除了原因，就该检查您的系统配置了。为此，您需要以安全模式启动计算机(boot your computer in safe mode)。
当您处于安全模式时，只会运行基本程序，因此您可以尝试在该模式下输入，看看问题是否仍然存在。如果是这样，则可能是软件问题。
关闭按键重复(Turn
Off Key Repeat)
在Mac笔记本电脑上，有一个名为Key Repeat的设置，旨在让您按下一个键并按住它来一遍又一遍地键入相同的字母，直到您松开它。如果您在多个键上遇到重复键，这可能是罪魁祸首。
在Spotlight 搜索(Spotlight Search)栏中键入键盘(Keyboard)以打开您的键盘设置。在键盘(Keyboard)选项卡中，将按键重复(Key Repeat)切换为关闭。(Off.)
重置为默认(Reset
to Default)
在 Windows 10 中，您可以将键盘重置(reset your keyboard)为出厂设置。转到Windows Settings > Time & Language > Region and Language。在那里，您将添加一种新语言，将该新语言设为主要语言，然后将英语(English)移回顶部。这将重置键盘。
对于Mac，您可以通过重置 Mac SMC(resetting the Mac SMC)来重置键盘。最简单的方法是取出电池，按住电源按钮五秒钟，然后重新安装电池。选取Apple > Shut Down。
计算机关闭后，在同时按下电源按钮的同时按下Shift、Control和Option键。(Option)按住十秒钟，然后松开所有键。当您再次按下电源按钮时，您的计算机将启动。
Fix Repeating Keys With These Tips
If you’ve ever had a repeating key, уoυ will know how annoуing it can be. Every time you have to double back to erase a duplicatе “i” or “s,” you lose a little time. It may even interfere with your thought flow, killing your productivіty throughout the day.
The good news is that repeating keys are typically easily fixed, especially if it ends up being a hardware problem. Here are a few troubleshooting steps to take to fix those pesky repeat letters.
Start
Simple
As with any computer issue, it’s important to tackle the simplest troubleshooting steps first. If you have another keyboard, plug it in and start typing.
This will help you narrow down whether your existing keyboard is the problem.
Clean & Repair Keys
The next fairly simple step is to clean your keyboard. You should already give your computer a thorough cleaning on a fairly regular basis, but your keyboard is especially prone to dirt.
Shut the computer down and turn the keyboard upside down to shake out any loose debris. Wipe the keys down and used canned air to loosen any dirt that might be trapped. You can then turn the keyboard upside down again to eliminate what the canned air has dislodged.
If that doesn’t do the trick, you may need to remove the keys that are repeating and clean beneath them with a cotton swab.
Run
Operating System Updates
If you haven’t updated your system recently, a quick operating system update can never hurt. On a Windows 10 machine, go to Start > Settings > Update and Security > Windows Update.
For MacOS, click on the Apple icon in the upper-left corner and choose App Store>Updates. You can also use a program like Windows Driver Booster to check for any outdated keyboard drivers and make them current.
Check
System Configuration
Once you’ve physically inspected your keyboard and ruled that cause out, it’s time to check your system configuration. To do this, you’ll need to boot your computer in safe mode.
Only essential programs run when you’re in safe mode, so you can try typing in that mode and see if the problem persists. If it does, it’s likely a software issue.
Turn
Off Key Repeat
On Mac laptops, there’s a setting called Key Repeat designed to allow you to press on a key and hold it to type the same letter over and over until you release it. If you’re experiencing duplicate keys on more than one key, this could be the culprit.
Type Keyboard in the Spotlight Search bar to open your keyboard settings. In the Keyboard tab, toggle Key Repeat to Off.
Reset
to Default
In Windows 10, you can reset your keyboard to its factory settings. Go to Windows Settings > Time & Language > Region and Language. There, you’ll add a new language, make that new language the primary one, then move English back to the top. This will reset the keyboard.
With a Mac, you can reset your keyboard by resetting the Mac SMC. The easiest way to do this is to remove the battery, press and hold the power button for five seconds, and reinstall the battery. Choose Apple > Shut Down.
Once your computer is off, press the Shift, Control, and Option keys while pressing the power button at the same time. Hold for ten seconds, then release all keys. When you press your power button again, your computer will boot up.
