To check laptop battery health on Windows, use the Command Prompt by typing powercfg /batteryreport and pressing Enter, then navigate to the generated HTML file to view design capacity versus current full charge capacity; a significantly lower current capacity indicates poor battery health. Alternatively, access the BIOS/UEFI settings during startup and look for a battery health option under the general or overview section.
Method 1: Using the Command Prompt (Windows)
1. Open Command Prompt:
Click the Start button and type cmd in the search bar, then right-click on Command Prompt and select Run as administrator.
2. Generate the Battery Report:
In the Command Prompt window, type the command powercfg /batteryreport and press Enter.
3. Locate the Report:
A message will appear indicating the location of the battery report file, usually C:\Users\[YourUserName]\battery-report.html.
4. View the Report:
Open File Explorer, go to your user folder, and then open the generated HTML file to view your battery's design capacity and full charge capacity.
5. Check Battery Health:
Compare the Full Charge Capacity with the Design Capacity. A significant difference, where the full charge capacity is much lower than the design capacity, indicates a worn-out battery.
