Hello, 
I have a Xiaomi Mi Pad 4 and it seem already to have died.
It doesn't start - no matter how long I press the button and it also doesn't start into bootloader.
I had no custom Rom or recovery installed.
I thought it could be the battery - device is pretty old, but even with the new one nothing happens.
Did somebody maybe had the same issue and/or has an idea what it "usually" else can be? I know... It CAN be every little component... But maybe some known one, what happens pretty often on Pad 4.
