Hello everybody,
I start to become crazy now… My X98 Pro (K9C6) was working well but since yesterday it is very difficult to charge under Android.. that is detecting only “USB charging mode” and really not want to accept the power of my AC Power supply.. I checked and with others AC power (all 2.5 A. SAMSUNG and others…)… under android only keeping sloooow charging mode “USB Charging”..
NOTE : if I switch to windows 10 mode It charges correctly…
What went wrong in my android system ? I reinstalled it twice to factory settings… problem still there…
Any help or clue please ?
February 19, 2017 at 6:36 pm #62472I have the same problem. At the android charging is only 0.4A and USB OTG does not work.
In windows charging is correct but as disconnecting the cable charger, a battery icon shows charging the tablet.I found something like this:

March 10, 2017 at 2:30 pm #63221No. even switch on it does. but the problem is that when you touch the power managment on windows side it make crazy things to the kernel and this is dead after… I still gone on Mirek V6 1.5/56GB android only but still havin problems… when charge is about 88% and more… the kernel a like “fighting together” and tablet can’t stay sleeping mode … it restart all the time because this stupid kernel from windows is somewhere again… or that is bios need to update maybe….
