Charging error

Jun 13, 2014
Good night

I have a MIPAD which if ignited being unplugged to turn on and can not charging or connecting to a computer. But the otg cable if recognized.

When this happens if you turn off the MIPAD it enters loop. Out MI logo and then the symbol of the battery, so repeatedly. Only disappears if I connect the USB cable and light.

Then it gets loaded and disconnect the cable is stopped.

But if I turn on MIPAD the usb cable connected to light up the main menu while I can charge it anytime.

And the computer recognizes. I changed several times the ROM, I flashed through fastboot, I made full wipe and still the same. That can happen?
