Here is the output from acpi_listen: The only thing I do is first unplugging than I wait some second and I plug the AC-power in again. As described above, the screen blanks (as if I closed my laptop lid), when I plug the AC-power in again, nothing happens. (The screen stays blank - but I can wake it up by pressing any key)
~$ sudo acpi_listen [sudo] password for xxx: ac_adapter ADP1 00000080 00000000 processor CPU0 00000081 00000000 ac_adapter ADP1 00000080 00000001 processor CPU0 00000081 00000000 Further observation: When the the screen is blanked, I can also wake it up by pressing any key on my keyboard even with unplugged AC-power - however in this case the screen wakes up dimmed. By the way - if I close the lid of my laptop, then acpi_listen does not show any output. I hope this is helpful.
