Before you think about buying a new battery for your laptop, it\u2019s essential to <\/span>make sure the battery is really faulty<\/a><\/b>. With a simple command, you can check the condition of the battery yourself without removing it or calling a technician.<\/span><\/p>\n

Run the diagnostic from the system console<\/strong><\/h2>\n

Access the system command<\/span><\/h3>\n

To start, <\/span>right-click the Start button<\/b> on your system, located at the bottom left of the screen. In the menu that appears, select <\/span>\u00ab\u00a0Command Prompt (admin)\u00a0\u00bb<\/b> or the equivalent option depending on your Windows version.<\/span><\/p>\n

A black window (console) will then appear. Where you see the path <\/span>C:\\WINDOWS\\system32><\/span>, <\/span>type the following command<\/b>:<\/span><\/p>\n

bash<\/span><\/p>\n

Copy code<\/span><\/p>\n

powercfg -energy<\/span><\/p>\n

Then confirm by pressing <\/span>Enter<\/b>.<\/span><\/p>\n

Wait for the energy analysis to complete<\/span><\/h2>\n

Windows will now run a <\/span>full analysis of your system\u2019s power consumption<\/b>. This may take around a minute. At the end, a message appears telling you <\/span>where the generated report file has been saved<\/b>.<\/span><\/p>\n

\n<\/span> An energy report has been saved to C:\\WINDOWS\\system32\\energy-report.html.<\/span><\/p>\n
