Hello I suffered the same problem, I am using the tablet normally when it doesn’t turn on anymore. I am using Windows 10 before I booted my Tbook 11 and cannot do so. I have followed instructions to hold power button for 20seconds and release for 5 seconds then turn the power on again until it powers up. Still nothing. Please help guys. It is frustrating this is barely 3 months and now won’t power on. Any solution please.
Your help will be very much appreciated.
