How to find the health of the battery in your laptop in Windows 7

How will you find the health of your battery in your laptop??

This is easy my friend.

Open Command Prompt. (Run > cmd)

Type “powercfg –energy” in command prompt without quotes.

A HTML file named "energy-report.html " will be generated and  stored in your Primary Hard drive letter drive, say C drive.

Open the html file and there you can see something like
  •     Design full Charge 
  •     Last Full Charge
The lower the value of the Last full charge than the design full charge, the lower your batter has gone down in its efficiency and capability!!!!!!!!!
