My Nexus 7 won't turn on
1. Plug your Nexus 7 into its original ASUS power adapter using the charger's original USB cable, ensuring that the power cord is securely connected to the tablet and the power adapter. Also, make sure you're using a functioning power outlet.
2. Wait for one minute, checking to see if a charging icon appears on the screen.
3. Press and hold the Power button for at least 15 seconds to see if the device powers on.
4. If you still can’t turn on, please return device to ASUS Service Center for check.
