Of possible interest to those with Laptops or Tablets the command copied below entered into CMD Admin generates a fairly detailed report (at least in W8.1) on the battery(s) installed and recent usage history.  I find it interesting and useful for keeping track of how my single battery is doing.  One criticism some users of some Laptops or Tablets might have of their portable device is that the battery does not last as long as they would like. It does not matter much to me as I mainly use my Tablet as a small Laptop, in the home, connected most of the time to AC.  The reports generated so far have been informative, especially the timeline of usage and charging / none charging, but for some reason they lack some data on usage --- the headings and a graph appear but the data is absent.  I presume this is due to the the instructions not being quite correct / complete.  Would anyone know what corrections / additions are required?


Enter the following in Command Prompt:


powercfg /batteryreport /output %tmp%\battery-report.html
ping localhost -n 2 >nul
explorer %tmp%\battery-report.html

The above is a good tip. I would like to add that the battery report switch of powercfg is only available on Windows 8 and above.


For Windows 7 you can use


powercfg -energy.
