Built-in keyboard and trackpad remain active, leading to accidental inputs. Diagnostic Steps Taken: 1. Checked 'sudo libinput debug-events', which prints no output or swit= ch events when the device is flipped. 2. Checked raw kernel events using 'sudo evtest'. Tested event node "In= tel HID events" and "MSI WMI hotkeys". Neither device lists 'Event code 1 (SW_TABLET_MODE)' under supported events, and zero raw event lines are prin= ted to the console during physical screen transformation. Conclusion:=C2=A0The motherboard's ACPI WMI or Embedded Controller (EC) eve= nt code for tablet mode is missing or unmapped in the current kernel drivers (intel= _hid / msi_wmi). 3. I have attached the raw 'acpi_table.dat' dump generated via acpidump= to help trace the missing WMI/EC physical switch events.
