I have an Asus ROG G751JT and recently, it stops recognizing the charger with no explanation. The problem then fixes itself randomly also. The problem is not with the charger and holding down the power button for 30 seconds does nothing. Some actions that have resulted in the charger not being recognized are: unplugging the computer for 10 minutes, connecting a wired Xbox controller, and disconnecting the controller. The connection returns after I leave the computer alone for about an hour.
