Chuwi Ubook X - Strange Hibernation Mode Behaviour

Hello together,
since about two or three weeks I am expiriencing severe problems with my Ubook X. When I leave it in standby, after some time it switches into hibernation mode. This alone would not be a problem, but I have to hard reset it every time afterwards because it won’t wake up again. Is there a fix?

I am using the factory set energy mode btw

I’m having the same problem too, and could not find any solutions.

I disabled hybrid sleep mode and didn’t have the problem since then.
However now the tablet sometimes won’t charge untill i remount the battery in software…
