Some that did fresh Windows 10 installs on their new F5’s from Teclast have been experiencing driver issues and no keyboard being disabled in tablet mode. I just got my Teclast F5 (geat little laptop by the way) and made a Macruim backup of the SSD it has been added to the Teclast F5 drivers page for those interested.
