Use Win7 power efficiency analysis tool to generate large power consumption

People who go out often can bring their laptops and work anywhere. In general, the power of the laptop can last for 3-4 hours, but sometimes you will find that it doesn't take long for the power indicator in the lower right corner of Win7 to call the alarm. If you suddenly encounter this situation, you can basically rule out the battery life problem, but because a program running in the system is too power-hungry. We can use Win7's own power efficiency analysis tool to extract the large power consumers in the system.
To open the power efficiency analysis tool, we need to open the command window as an administrator. Open “Start - All Programs - Attachments'; Right click on “command prompt"> Select “Run as administrator”.

Run the command prompt as an administrator
If you jump out of the User Account Control window, press “Yes  Continue.
