With the ThinkPad X1 Yoga 4th, the tablet mode (which disables keyboard, trackpoint and trackpad) isn't correctly enabled when the screen is folded over **after waking up from hibernation**.

WORKAROUND: Suspend and wake up again. Then the tablet mode works again.

1. Go into hibernation mode.
2. Wake up from there.
3. Fold over screen.

touchpad,keyboard and trackpoint still work

touchpad,keyboard and trackpoint should be disabled.

acpi_listen doesn't report any events when the tablet is folded into tablet mode when in the state described above.
