Using the Built-in Windows 10 Power Supply Checker

Windows 10 has a built-in tool that allows you to check the status of your power supply. Here’s how to use it:

  1. Press the Windows key + R to open the Run dialog box.
  2. Type “cmd” and press Enter to open the Command Prompt.
  3. In the Command Prompt, type “powercfg /batteryreport” and press Enter.
  4. A battery report will be generated and saved to your computer. You can find it in the C:\Windows\System32 folder.
  5. Open the battery report and scroll down to the “Battery life estimates” section.
  6. Look for the “Battery capacity history” and “Battery life estimates” sections. If the numbers are significantly lower than the original capacity, it may indicate a problem with your power supply.

Using Third-Party Software

There are also third-party software programs that can help you check your power supply. These programs provide more detailed information and can help you diagnose any issues. Some popular options include HWMonitor, AIDA64, and CPU-Z.
