hi everyone…was reading, didn’t exactly find my answer (so, sorry if this topic has already been addressed).
My device: UBOOK PRO 12.3 N4100 Processor.
Arrived today 20 April 2020. I have been charging the ubook pro from about 12pm and it shows a red light when the adaptor is plugged in (i assume that is to indicate “charging in progress”)
At about 8pm, i decided to turn it on and it still shows low battery also ,the red light on. took off the power adaptor and it just went off.
i would recommend to open the ubook pro up and check if the cable is connected to the mainboard.
my ubook pro felt down one time and i had the same problem. after open it up i saw that the cable was not pluged in. i just put the cable back in and i worked like a charm now again.
just unscrew the 2 screws, behind the kickstand and slowly open it up from left to the right and around the corners, you will hear the charactaristical click sound…
