Plug it in and charge it
It may need charged.....try that first. Push and hold the on/off button until it comes on, sometimes this might take a few seconds. If that doesn't work and you've charged it, you may need a new battery.
Lolz. I think your
kindle power battery has been fully discharged. You need to plug into
charging and get it charge. But still you are not able to switch it on than
call kindle customer service
