    Just know keep this in your mind. High Temperature is the worst enemy for your Laptop’s Battery. Try not to over-heat your laptop and always remove the charger as soon as your laptop gets charged.

    in my windows 7 the html file does not open.how to open it.in firefox it shows as-
    File not found

    Firefox can’t find the file at /C:/Windows/System32/energy-report.html.

    Check the file name for capitalisation or other typing errors.
    Check to see if the file was moved, renamed or deleted.

      Due to security protocol, you need to find the file in System32 and put in on your desktop or someplace outside of the Windows folder. It will open without problems after that.

    when we open command window and “powercfg /energy” we were asked “this command requires administrator privileges and must be executed from an elevated command prompt”. so what we must do

    • Reply jigar Tank September 12, 2013 at 10:48 am

      As it says, You Must be an Administrator in order to perform this task.
