Thinkpad T410 Win7下接USB设备反应慢

症状：同事的T410接U盘或者别的USB设备的时候会像死机一般静止2到3分钟才有反应，在这个时候无论是鼠标还是键盘都不工作。

原因：Thinkpad驱动与win7系统冲突

 

解决方法：网上搜索了下，找到有不少文章提到这个问题。以下是解决方法：

        1、只适合用ThinkPad Win7的系统(不管是32位还是64位,也不管是啥子语言的系统更不管是啥机型).

　　2、注意：确保"C:\ProgramData\Lenovo\LenovoTvtTools"下的文件都还在

　　造成慢的缘故原由在于Lenovo ThinkVantage Tools下的*.devicemetadata-ms文件与WIN7原有的文件有重复或者冲突，该方法是将所有的*.devicemetadata-ms文件先删除，再从头导入Lenovo ThinkVantage Tools下的*.devicemetadata-ms文件，就可以解决这个不懂的题目

　　。要是"C:\ProgramData\Lenovo\LenovoTvtTools"下的文件有丢失的，转到C:\ProgramData\Microsoft\Windows\DeviceMetadataSto re下各文件夹中把最大最新的devicemetadata-ms文件留着，别的都删除便可

　　要是"C:\ProgramData\Lenovo\LenovoTvtTools"下的文件还完整的将以下内部实质意义（蓝色部份）COPY到新建的文这篇文章档然后另存为.bat 的文件运行便可，注销重登录后定起作用。

　　@echo on

　　cd "c:\ProgramData\Lenovo\LenovoTvtTools"
