I'm not sure whether this is a hardware or software problem. During the last couple of weeks I found my Asus transformer 2 in 1 randomly switching into tablet mode. Initially I could switch it back, but now, although it says tablet mode is off, the keyboard/touchpad do not work. Effectively, it's stuck in tablet mode. The transformer functions perfectly as a tablet. I made sure full screen was off, tried the registry key fix, checked (in device manager) that the touchpad driver is up to date. Would I expect to see errors in the event log if it was hardware? Is it possible that the pins that connect/detach screen from keyboard have failed? How to tell? Windows 10 1909. Anybody who can help, I'd be very grateful.
