2. Prevent your laptop from charging USB devices

You can disable a setting in the BIOS to prevent your laptop battery from draining when turned off. This setting determines whether devices connected to the laptop continue to receive power in a low-power state.

You can usually find it in the USB or Power Management section of the BIOS, but keep in mind that the interface may vary depending on the manufacturer. With a bit of searching, you should be able to locate the setting and disable it. This way, your laptop’s battery won’t lose power when turned off.

3. Activate deep shutdown mode

To resolve the issue of laptop battery draining after shutting down, you can try performing a deep shutdown by pressing and holding the Power button for approximately 15 seconds after your device has shut down. This method will force your laptop to enter the deep shutdown mode.

4. Disable Fast Startup using Command Prompt

Disabling Fast Startup using Command Prompt may stop Windows battery from draining after shutdown by deactivating Fast Startup, causing your computer to experience incomplete shutdown. You can accomplish this with a simple command. Here is how to disable Fast Startup using Command Prompt:

5. Shutdown Computer instead of hibernating or putting the laptop to sleep

When you put your computer to sleep or hibernate, it saves its current state to memory or disk. When you turn it back on, this mode quickly lets return to your work. However, the computer still consumes power to sustain the memory or disk.

If you plan to stay away from your computer for an extended period, it’s better to shut it down completely. This mode will help conserve battery power, especially if you use a laptop without a power outlet.

Although hibernation and sleep mode use less energy than normal computer usage, they still consume some power. Shutting down your computer saves the most energy, especially if you will not use it for a long time.

6. Update Battery driver

Updating your battery driver can help to fix Windows battery draining after shutdown by fixing bugs in the driver that may be causing the battery drain, adding support for new features, and ensuring that the driver is compatible with the latest version of Windows. To update your battery driver, follow these steps:

  1. Hit the Windows + X hotkeys and select Device Manager from the list.

Whether by adjusting power settings, updating drivers, or performing a deep shutdown, these fixes are proven solutions for battery drain issues in Windows laptops. Following these trusted fixes can optimize your laptop’s battery performance and help you enjoy longer battery life.
