************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

你需要安装电源管理相关的驱动程序，比如：

这个驱动可以在设备管理器中自动完成安装，如果还有问题，请继续反馈，感谢。

之前的就已确认安装该驱动。

正常加载IBMPmDrv，试了一台更老的t61，同样的错误。
另外像yoga系列虽然有电池管理但没有”Lenovo PM device“，多了一个 “Lenovo ACPI-Compliant Virtual Power Controller” AcpiVpc.sys 这个系列肯定和X、T、R系列不通用。
