I use it on battery. No problem whatsoever when plugged in.
My model is k9c3. After trying different things and even nearly bricking my tablet trying to flash android, I managed to recovered Windows 10 image of k9c6 model.
After that I let windows 10 update and use Intel update utility as well.
I haven’t had a crash after using your method. But I’m not sure if it will continue because when I add the additional power option using your method, the default option for battery is already passive. It’s only active for plugged in.
Also, in the intel graphic option, I just crank up everything. In 3d settings, I set best performance – override application…
In battery settings, I set to best quality.
Will update the status when I use the tablet a bit more.
