Microsoft introduced a handy new command in Windows 7 to help you figure out your battery health.
To use it, do the following:
• Open a command prompt (as ‘administrator’)
• Type the following:
• Give it time to run for 60 seconds
• An html file will be created in your Profile directory. In my case, I get the following output from the screen”
C:\Users\hschoeman>powercfg -energy Enabling tracing for 60 seconds... Observing system behavior... Analyzing trace data... Analysis complete. Energy efficiency problems were found. 25 Errors 9 Warnings 23 Informational See C:\Users\techedemic\energy-report.html for more details.
The part in red above shows the location of the output file. Sad but true, my battery is dying – it only charged about 39% on the last charge:
