First issue is, (i think) the power button is broken, because of my 4 years old son oftenly push it so hard.
And then it begin to randomly shutdown, first thought is, maybe the power button is pushing a some kind of hardware inside so the device is react like it was being turn off.
Sometimes i can still turn on the device with the power button, but when it does, it came the second issue, the device fail to reach the bootvideo or reach it but then shutdown itself again and it began to restart again, and failed again.
But the strange is, i can power on the device without any fail if only the charger is mounted, and as long as the charger is mounted, it never get shutdown itself.
Any solution for this guys? or maybe some kind of battery or AC or whatever hardware is probably got some errors?
Or maybe it's just software issues? I don't mind to reflashing it, but just want to make sure it will solved the problems (too busy to restore all the files and apps)
And my N9 is in some kind of stock configuration, no N9QT installed.
Thanks for any answers.
