Hi People,
I had the same issue as described before. My TBook 11 was generally bricked and finally I gave it to my 9yo son to let him play with some USB cables I have in my desk. Accidentally he SOLVED the issue by connecting USB to ETH adapter through OTG (microUSB to USB A Female) cable and plugging it into router’s ETH port. With having such daisy chain connected Tbook11 powered on and displayed low battery warning. I disconnected my son’s magic cable set and putted tablet on charger then. Charging was accepted and device is still running till now.
Situation repeats every time battery runs flat-out and TBook goes down – I have to plug it to router again just to wake up the BIOS.
Therefore I just set power saving to hibernate at 20% which basically solves the issue permanently.
My conclusion is following: Teclast used poor battery which’s voltage goes so low that BIOS power circuit can’t start due to overcurent protection (low voltage = high current). All you need to do is keep your battery high enough to avoid such situation. This works in my case at least 😉
Good luck and let me know is somebody else managed to unbrick TBook11 in this way.
Regards
Marek
