How to Enable USB 2.0 Port Charging When Laptop is Asleep

USB 2.0 ports on laptops are commonly used for charging devices such as smartphones, tablets, and other portable gadgets. However, by default, most laptops disable USB port charging when they are asleep or in hibernation mode. This can be frustrating if you want to charge your device overnight or when you're not actively using your laptop. In this article, we will guide you through the steps to enable USB 2.0 port charging even when your laptop is asleep.

Before we begin, it's important to note that not all laptops support USB 2.0 port charging when asleep. This feature depends on the laptop's hardware and BIOS settings. So, it's recommended to check your laptop's user manual or manufacturer's website to confirm if your specific model supports this feature.

Step 1: Accessing the BIOS

The first step is to access your laptop's BIOS settings. The BIOS (Basic Input/Output System) is a firmware that controls the basic functions of your computer, including hardware settings. To access the BIOS, follow these steps:

1. Turn off your laptop completely.
2. Turn it on and immediately press the key specified by your laptop's manufacturer to enter the BIOS. The key is usually displayed on the startup screen or mentioned in the user manual. Common keys include F2, F10, Del, or Esc.
3. Once you're in the BIOS settings, navigate using the arrow keys on your keyboard. Look for a section related to USB settings or power management.

Step 2: Enabling USB Charging

Once you've accessed the BIOS settings, follow these steps to enable USB charging:

1. Navigate to the USB settings or power management section.
2. Look for an option related to USB charging or USB power during sleep mode.
3. Enable this option by selecting it and changing the value to "Enabled" or "On".
4. Save the changes and exit the BIOS settings. This is usually done by pressing the F10 key and confirming the changes.

After saving the changes and exiting the BIOS settings, your laptop will reboot. Once it has restarted, you can proceed to the next step.

Step 3: Configuring Power Settings

Now that you've enabled USB charging in the BIOS, you need to configure your laptop's power settings to allow USB charging when it is asleep. Follow these steps:

1. Right-click on the battery icon in the system tray and select "Power Options".
2. In the Power Options window, click on "Change plan settings" next to the power plan you are currently using.
3. Click on "Change advanced power settings" to open the advanced power settings dialog.
4. In the advanced power settings dialog, expand the "USB settings" category.
5. Look for an option called "USB selective suspend setting" and expand it.
6. Change the setting to "Disabled" for both "On battery" and "Plugged in" modes.
7. Click "Apply" and then "OK" to save the changes.

With these power settings configured, your laptop will allow USB charging even when it is asleep or in hibernation mode. Now you can connect your device to the USB 2.0 port and it will continue to charge.

It's important to note that enabling USB charging when the laptop is asleep may have an impact on the laptop's battery life. If you're using your laptop on battery power, it may drain the battery faster. So, it's recommended to use this feature when your laptop is connected to a power source.

Conclusion

Enabling USB 2.0 port charging when your laptop is asleep can be a useful feature, especially if you want to charge your devices overnight or when you're not actively using your laptop. By following the steps outlined in this article, you can easily enable this feature in your laptop's BIOS and power settings.

Remember to check your laptop's user manual or manufacturer's website to ensure that your specific model supports USB charging when asleep. If you encounter any issues or have further questions, it's recommended to reach out to your laptop's manufacturer or seek assistance from a technical professional.
