PowerFool – A Power Tool & Device Checker
When researching some troubles we had with BranchCache in WinPE we needed to mimic the Battery detection system available in BranchCache. So this tool was born. We found the issue in BranchCache and it wasn’t related to the Power detection. We proved that with this nifty little tool. Should run on most platforms (including WinPE) as long as the Visaul C++ runtime for 2012 is installed.
Other usage can be to find out the estimated battery life before kicking of a job, detecting power cable plugged in, detecting Slates and tablet devices.
What does the tool return, well quite a bit of info:
