My brand new MiPad 2 will not work. Can I ask for someone's help? I purchased a Mi Pad 2 with supplier-installed multi-language MIUI ROM for global, the version is MIUI 7.0 Stable 220.127.116.11. It is fully charged, but when I press the power button on the side of the device to wake up the device, it does not work. The screen remains blank. Because of this, to access the device I have to plug the charger in and this then lights up the device and brings me to the home screen where I can slide to unlock. After this, I can press the power button to put the device to sleep, but if I press the power button again the device will not wake up. The only way the device will wake up is if I plug in the charger. I went to settings and turned off the smart screen option, but this did not help. Please, please can a kind person help me. Thank you.
