I also experienced the Intel driver incompatibility issue but didn’t get the keyboard problem at that point or during further updates. It may be heat related though. Mine could be used for about 10-15 minutes from cold before producing the fault. Furthermore, the laptop appears to use the keyboard as a heat sink. Some drivers/packages can run the processor quite hard when updating. I still believe its a physical keyboard fault because with it disconnected the fault does not reappear.
The keyboard failure is actually the second fault I had, the first being the power supply jack plug shorting out and melting internally. This happened very early on in its life and the jack is an odd size too. I wonder if anyone else has had this fault?
Based on the comments in this forum there does seem to be a pattern here in the way Banggood Gearbest and Teclast are dealing (or not) with issues regarding these laptops.
