I wish they had given us the option to turn it off if it was an expected feature. My laptop is on a desk most of the time and it would have been nice if my type c peripherals shut down with the laptop itself

Hi @Maniya2002 ,

Thank you for reaching out to us.

The Type-C on the GA503RM supports charging even when the laptop is shut down and connected to AC power.

If you wish to disable this feature, you can only do so by disconnecting the AC power. The information above is provided for your reference. Thank you.
