thinkpad系列是商务本，注重稳定性。建议您调低画质，关闭不必要的程序试试！
或者优化下。
第一部分：卸载程序
依次进入“开始→卸载程序”
①首当其冲的就是诺顿杀软。名称是Norton Internet Security，从中找到它们，双击即可开始卸载。卸载后别重启，再卸载其他的软件。我们可以换其他的小型杀软，如微软MSE、小红伞、ESET等等这些轻量级软件，以节省资源的占用。
②Lenovo自带的两个工具：Lenovo Solution Center和Lenovo SimpleTap。经我个人的长期观察，这两个工具在任务管理器中占用的非常大，Solution Center虽可以开机禁止，但它却总是不定期地启动，而一启动就非常卡。SimpleTap根本没法开机禁止，在任务管理器所显示的进程当中，占用也非常大。故而可卸载它们，不是特别重要的工具。
第二部分：控制开机启动项、系统配置设定
点击开始菜单，输入“系统配置”，然后Enter进入。
点击“引导”选项卡，接着点击“高级选项”，确定后，点击“启动”选项卡，一般是硬件控制台、杀毒软件、电源管理、APS硬盘保护这些都开机启动，其他的应用软件启动项无需启动。像如图中的这些选项须开机启动，剩下的不用启动了，点击“确定”完成设置，系统会要求用户重启，先不重启，进行下一部分操作。
第三部分：禁用相关服务
点击“开始”，输入“服务”，按Enter进入，接下来会看到这样的界面，
下面的服务名称建议禁用：
Diagnostic Policy Service
Diagnostic Service Host
Diagnostic System Host
Program Compatibility Assistant Service
Security Center
Tablet PC Input Service
Windows Backup
Windows Defender
Windows Error Reporting Service
Windows Time
在这个窗口中找到这些服务，分别双击它们，在弹出的窗口中的下拉菜单选择“禁用”，然后“确定”完成设置。
第四部分：切换独显
对于搭载有NVIDIA独显的机型。切换独显的步骤是这样的：右击桌面→NVIDIA控制面板→管理3D设置，在“全局设置”选项卡下，选择“高性能NVIDIA处理器”，最后确定完成设置。在只使用独显情况下，系统内存占用会小很多，独立显卡有自己独立的显示内存，不再与系统内存共用。
