一、ps1脚本

文件名：KeyboardCheck.ps1

Function WaitForKeyPress($TimeoutInSeconds) {$KeyPressed = $false$deadline = (Get-Date).AddSeconds($TimeoutInSeconds)# 显示提示信息Write-Host "请在 $TimeoutInSeconds 秒内按下任意键(长时间没有检测到按下按键会被认为键盘可能有问题)" -ForegroundColor Blue# 使用 ReadKey 和 Sleep 来实现等待while ((Get-Date) -lt $deadline -and !$KeyPressed) {if ([Console]::KeyAvailable) {# 按键被按下了$key = [Console]::ReadKey($true)  # $true 表示不显示按键Write-Host "检测到按键 '$($key.KeyChar)' ($($key.Key))" -ForegroundColor Green$KeyPressed = $true} else {Start-Sleep -Milliseconds 100  # 延迟 100 毫秒}}if ($KeyPressed) {Write-Host "在 $TimeoutInSeconds 秒内按下了按键。"} else {Write-Host "$TimeoutInSeconds 秒内没有按键！你的键盘可能有问题！" -ForegroundColor Red}# 返回是否检测到按键的值return $KeyPressed
}Function ExitWithCountdown {param ([int]$Seconds = 10  # 默认倒计时时间为10秒)Write-HostWrite-Host "脚本将在 $Seconds 秒后自动关闭窗口" -ForegroundColor Magentafor ($i = $Seconds; $i -gt 0; $i--) {Write-Host -NoNewline "`r正在退出... {$i}秒后关闭窗口..."Start-Sleep -Seconds 1}
}# 获取5秒内是否按下了任意键
$IsKeyPressed = WaitForKeyPress -TimeoutInSeconds 5# 根据 $IsKeyPressed 的值调用 cmd.exe
if ($IsKeyPressed) {Start-Process -FilePath "cmd.exe" -ArgumentList "/c echo cmd_t" -NoNewWindow -Wait
} else {Start-Process -FilePath "cmd.exe" -ArgumentList "/c echo cmd_f" -NoNewWindow -Wait
}# 延迟退出
ExitWithCountdown

二、开机自启动

打开路径：%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup
将下面的代码保存到名为start_KeyboardCheck.bat的文件中
(代码中的文件路径自行修改)

@echo offecho.
echo ScriptPath:%~dp0set "ps1Path=C:\MyScript\KeyboardCheck.ps1"if exist "%ps1Path%" (echo File "%ps1Path%" existsPowerShell -NoLogo -ExecutionPolicy Bypass -File "%ps1Path%"
) else (echo File "%ps1Path%" does not exist, please check the path!pause
)

三、效果

四、有什么用

额*****，没啥用，配合这个知乎贴如何禁用笔记本自带键盘？，免得真的没键盘用😓
