 Hi @Amitrcsk, very sorry to hear about this.

If the power button isn't working correctly, your device will need to be examined at an authorized service centre and your Local support team will assist you further.

If you have any questions regarding local service routines, warranty and so forth, they will gladly assist you with this as well.

I hope that helps!
