Step 1: Open Command Prompt

To begin testing your laptop battery health, you'll need to access the Command Prompt with administrative privileges. Here's how:

1. Press the Windows + X keys on your keyboard to open the Power User menu.
2. Select Command Prompt (Admin) or Windows PowerShell (Admin) from the list.
3. If prompted by User Account Control (UAC), click Yes to proceed.

For more information on using Command Prompt, refer to the official Microsoft Support documentation.

Step 2: Generate Battery Report

Once the Command Prompt is open, you can generate a detailed battery report. Follow these steps:

1. Type the following command and press Enter:

powercfg /batteryreport

2. This command will create a battery report and save it to your user directory.
3. The file path will be displayed in the Command Prompt, typically under C:\Users\[YourUsername]\battery-report.html.

For a deeper understanding of the powercfg command, visit the Microsoft Docs.

Step 3: Analyze the Battery Report

After generating the battery report, you'll need to analyze it to understand your battery's health. Here's how:

1. Navigate to the file path provided in the Command Prompt.
2. Open the battery-report.html file in your preferred web browser.
3. Review the sections, including Installed Batteries, Recent Usage, and Battery Capacity History.

Step 4: Check Battery Capacity

One of the most critical aspects of the battery report is the Design Capacity and Full Charge Capacity. Here's what to look for:

• Design Capacity: The original capacity of your battery when it was new.
• Full Charge Capacity: The current maximum capacity your battery can hold.

Compare these two values to determine how much your battery has degraded over time. If the Full Charge Capacity is significantly lower than the Design Capacity, it may be time to consider replacing your battery.

Step 5: Monitor Battery Usage

The battery report also provides insights into your laptop's recent usage patterns. This section can help you identify any unusual battery drain. Here's how to use it:

1. Scroll to the Recent Usage section in the battery report.
2. Review the timestamps and battery drain percentages to identify any irregularities.
3. If you notice excessive battery drain, consider closing unnecessary applications or adjusting your power settings.
