I think it is the Android software issue. If reinstalling Android can't solve your problem, i don't know how to help you. There are only two version Android for your tablet. But it doesn't work for your tablet.
Please contact your seller and return tablet for repair.
after a lot of tests i still have the power issue on Android.
I don't think is an hardware problem since windows works well.
Is there any BIOS setting related to this that i could try to change?
can you send me the list of settings/values?
i have same news, i can say the tablet is not totally dead when i wake it up from sleep, but probably the problem is the screen cannot turn on.
I made a logcat, can you please analyze it and let me know something?
