How to run BatteryMon in WinPE

[Pindish]

I can start up BatteryMon (2.1) in WinPE 3.1. But BatteryMon detects no battery. Run BatteryMon in Windows Vista on the same machine, it works.

Please advise how to run BatteryMon in WinPE.

Thanks.

My guess is that you are missing the device drivers when you boot into WinPE.

What are the required drivers? Thanks.
