Answer

On MSI laptops, the USB Type-A ports may continue supplying power when the system enters Sleep, Hibernation, or Shutdown. This allows connected devices, such as a smartphone or wireless mouse, to remain powered or continue charging. To enable or disable this function, please refer to the following information.



Supported features may vary depending on the model; please refer to the actual machine specifications.

If the USB Power Share option can't be found in the following steps, USB Power Share is not supported.

FAQ



Q: Why does a USB device remain powered after the laptop enters Sleep or shuts down?



A: The USB power function may be enabled in the BIOS. When enabled, supported USB Type-A ports can continue supplying power during Sleep, Hibernation, or Shutdown.



Q: Does disabling USB power affect normal USB operation while Windows is running?



A: No. This setting controls USB power behavior during Sleep, Hibernation, or Shutdown. USB devices should continue working normally while the system is powered on.



Q: Can USB power during Sleep or Shutdown increase battery consumption?



A: Yes. A connected USB device may continue drawing power while the laptop is sleeping or shut down. Disabling this function may help reduce battery consumption when USB power is not required.



Q: What should I do if the USB port still supplies power after the option is disabled?



A: Confirm that the settings are saved successfully, then restart the laptop and test again. If the behavior remains unchanged, update the BIOS to the version provided on the MSI website or contact MSI Support for further assistance.
