Why isn't my power button working

[Android Central Question]

My power button and my volume button just stopped working days ago,and I've tried everything to get it to work,even holding down the power button and volume button for 10 seconds, but it still isn't working,why??

Perhaps it needs repair. Try cleaning with an alcohol-soaked cotton button.

But it most likely is going to end up going to a repair shop.
