I had the same issue two times, probleme to power on or off the tablett with black screen, i don’t know how to resolve this issue, but it’s happend two times only. For the malware i found two, with malware bytes and reinstall a clear version of windows
I´m doing that too, reinstall a clear Windows version, just to be sure, but I will wait a few days, just in case a new version of Android Rom appears, and then do a repartitioning. For security I didn´t enter or used any password or anything in Windows. Just mess around.
My windows was totally clean. Reinstalling Win10 is a good practice but be carefull with drivers. Intel drivers for Z8500 are not freely available and those in techtablet repo are quite old. Regarding Android, it’s a ROM problem to be fixed (I hope soon) by Mirek in the future.
Have you got any problem reinstalling windows with the registration key and activation? Can you lost it?
