why i my asus expertbook laptops battery draining even when its shutdown

Hi there, I am John J.D., a fellow Microsoft user like you.

I understand you're having issues with your laptop battery, and I'm here to help. A significant drop in battery life while the laptop is shut down is indeed concerning. Battery capacity does decrease over time with use and environmental factors, so you might experience less battery life than expected, which can be normal.

Here are a few steps you can take to troubleshoot:

Power Drain Test: After shutting down, unplug any connected peripherals like USB devices, external mice, or keyboards. Sometimes, these devices can draw power even when the laptop is off.

Battery Health Check:

You can use the Command Prompt to generate a battery report that shows the battery specifications, usage, capacity, and life estimates. Here are the steps to do that:

> Open the Start menu and search for CMD > Click "Run as administrator".

> Type this and press Enter: powercfg /batteryreport

> The file location will be shown in the Command Prompt window. Open File Explorer, go to the folder that the report was saved to.

> Click the HTML link to view the detailed battery report.

Please share your results in your next response.
