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?
Finally i think i found out what the problem was and hope this will help people with my same problem
The problem of the black screen when pressing the power button in Android to wake up the tablet from sleep was related to a damaged SD card.
Fixing the SD card solved my problem and now the tablet works well
